Virtual loopback MIDI cable for Windows XP up to Windows 10, 32 and 64 bit.

This software can be used to create virtual loopback MIDI-ports to interconnect applications on Windows that want to open hardware-MIDI-ports for communication.

The ports created are unique for each user and only exist while the loopMIDI-application is running. So if you log-off, the created ports cease to exist.

When you close the configuration, the application will not terminate, but rather be minimized to the traybar. When you right-click on the traybar-icon of loopMIDI, you get an options-menu to either deactivate the application, configure the ports or to activate autostart each time you log on to the computer.

This software uses the virtualMIDI driver to actually create the ports.

WaveTableTester gives the exact numerical math for “Single Cycle” loops. It also tests and plays wavetables in basic mono synth engine. WTT uses 8 loaded wavetables for using single cycles as synth voices. WTT synth engine features Multimode SVF 3 LFOs(LFO has ability for modulating wavetable index partials) 2 EG with modulation routings. WTT is my test tool for complex wavetable oscillators. WaveTableTester=super fast/simple/easy way for me testing sample data created in AudioTerm.

Custom Wav Samples made in Audio-Term using original Prophets VS & PPG WAVE data:

XenoMorphic Resonator VST features 2x complex morphing oscillators each using custom banks of 32 Wavetables/Transwaves/Samples created in AudioTerm. Extreme modulation capabilities from 8 LFOs 2 Envelope Generators, Randomizer Sample Hold, plus 24 types of Ring Modulation. XMR Scans Wavetables with BPM sync LFOs. This Sound Design Tool also “spins” through selecting sounds or utilizes “Kaos” function for selecting random sounds using BPM sync. “XMR” also features dual SVF Multimode Filters that self resonate. My original concept was merely creating something that would play back wave files created in AudioTerm yet the vicious “Alien” emerged for orchestrating sinister SCIFI/Horror sounds. Time for making up some new custom banks for XMR in AudioTerm!

Revised Version now with rebuilt Index Modulation Wavetable Engines!

“I programmed a small windows based tool called “Komplex – Term” which can read and write WT files for the Terratec Komplexer. Further you can render it’s wavetables to wave format, so you can use it in your Wusikstation, VAZ Modular, Reaktor… . It also offers wave file resynthesis and some editing functions like reordering slices, drawing spectra, a free formant filter (similar to the kawai k5000)and so on. I wrote a short manual, but please excuse my poor english.”
Mathias Gurk

Here’s an explanation about the concept

(especially about the “KTERM/AUDIOTERM wavetable generator”)

Written by Mathias Gurk
AT was intentionally made for my personal use and “just for fun” to learn how to code in C – my version of “Hello world”.

There never had been ‘seroius’ plans for making it public when I started this project. Maybe this explains why it’s so ‘strange’. Due to very limited time and some health issues I used all of my energy for the program itself and not for writing a manual.
AT consists of different sections, KTERM<> is the one for creating “classic” wavetables for Dune2, serum, Komplexer and some other products.
KTERM<> is an additive synth: 33 slots with 64 bipolar sine partials each. It’s an emulation of the Terratec Komplexer wavetable osc, all other formats are derived from that model.
I chose this model because it has the right ratio of data amount and quality. Further many products beside Komplexer can use the results (converting wavetables which make full use of proprietary features of a certain product is much more difficult than converting normal audio data for different samplers).
AT has an automated file recognition and sorting system. It can distinguish a Komplexer *.WT file from a Dune2 *.WT file or from a Surge *.WT file… . Different file types are stored in different directories to keep track of which *.WT file belongs to a certain synth. Damaged and/or unknown formats are moved to a special ‘recycle bin’ folder (button RECBIN<> in the start page, here you get also information about the error).

Further the sound data folders can be individually moved to an abritrary location (because some synths require their files stored to a developer-defined location). This moving can be done using UTILITY<> and then selcting the PATHS<> page.

Regarding the proprietary wavetable formats (Surge, WaveGenerator, Dune2, EPS/ASR, Blofeld): AT can only load it’s own files. This is a required limitation, because the formats are VERY different (in data type, size, content, number of slots). All of these formats hold special synthesis data for reloading and instant playback in the browser pages. In some cases this additional dataset is encoded in the wavetable data itself (Blofeld, Komplexer). In other cases it’s appended. Editing these files outside Audio-Term will destroy these data, so don’t try that if you want to reload them later in AT.
Regarding the GUI: The lower button row holds the main pages and the playback buttons. The upper row holds the functions of a page and further sub pages / input options ( in that case the button name has an <> appendix)

The KTERM main pages:

SYSTEM<>
Here you can access the playback volume and playback speed of a wavetable. you also can empty all loaded data in RAM using FLUSH.

DISK<>
Depending on the file type you have different options. For all files you can switch the pages, search for a file name (FIND<>), rename and delete a file. You further can switch between the directories of the different file types using F_TYPE<> and call the windows explorer to get direct and full access to the current directory.
Further options depend on the file type. Wavetable files can be loaded directly, samples have to be analysed first. Single cycle waves are loaded from the assembling page ASSEM<> (see below).

VIEW<>
Here you can have a look on the ram data in different modes (waveform and spectral data). Some eye candy…

SLICE<>
This is the slice editor. You have access to the 64 bipolar partials (log scaling). WDRAW<> is a sub menu to draw the content as wave. The drawing then is analyzed and resynthesized. TOOLS<> hold some makro options for the partials (like normalizing or inverting). You should try the buttons and see what happens – the app won’t get broken.

If you don’t like the result you see/hear, press UNDO – it keeps track of the last 512 changes of the partial data.

ASSEM<>
Here the single cycles and wavetables in the different directories are used as ‘library’ to assemble new wavetables. Select source and destination slice with the SRC and DST buttons and transfer the data with SRC>DST.

ENV<>
On this page you also have access to the partials (bipolar, log scale), this time not 64 of a slice but a single partial over 33 slices of a wavetable. This is the envelope of a partial. The selected one has a fat line, all others are represented by thin lines. Very similar to the harmonic envelopes of the Fairlight CMI. On complex sounds this can look annoying. In this circumstance you can use VIEW to focus on the selcted envelope.

TEF<>
This is a special page which holds a lot of sub functions regarding
– polarity of the partials (PLOAR<>),
– amplitude scaling (SCALE<>),
– slice reordering (ORDER<>),
– a filter (FILTER<> – basically an additional “filter” slice with 64 partials, an envelope for shifting and access to the ‘library’ on disk to import spectral data)
– a formant shifter (SHIFT<>),
– a generator for filling the table with symmetry-modulated waves (SYMOD<>),
– and the interpolation function (IPOL<>).

The latter is very flexible – the goal is alwas to create a fully filled table from waves on arbitrary positions – even from a single wave. There are two interpolation algorithms: IPOL simply fills empty slices. STRETCH+IPOL fills the table by scaling the time base, which can be important especially for analyzed samples.
Two further additions:

OPTIMIZE button:
KTERM has an internal resolution of +-127 steps, but the dynamic of a 64 partial additive engine is much larger. Too large to use it without artificial limiting, a saw would be 50 times the amplitude if a single sine. OPTIMIZE adapts the partials to the limited waveform amplitude. In most cases this can be done automatically, but sometimes manual correction is required to get the best results out of the limted dynamic range.

POL_LOCK button:
KTERM uses bipolar sine waves, which improves the quality especially on sample resynthesis (otherwise everything would have a ‘sawtooth touch’). POL_LOCK tracks each of the 64 envelopes and corrects polarity jumps. In most cases this is usefull as it makes the spectral evolution over time more stable, but it changes the sound slightly. So whenever this button appears, you should try if it sounds better with or without POL_LOCK.
Okay, this short explanation isn’t a manual by far, but it explains some of my thoughts when I coded Audio-Term. I hope it was understandable a bit – I’m not a native speaker and also no sound engineer.

“Transwave – Term” (became Audio Term)

Audio Term was originally “Transwave” Editor for ENSONIQ .efe format

December 22, 2017 Hi everyone. Today I have very bad news. I have not heard from Mathias since August this year. He does not answer on Facebook or on mail. His Facebook friends have not heard from him for a long time. I know that he has health problems. I do not want to say more about that. Since he is the programmer, I can not give competent answers to technical questions. I only operate this site. OK. I’ll keep you up to date.

Here again the link to the download for Audioterm. There are always questions about updates. Mathias, the programmer of Audioterm, will not continue to develop the program. It is as it is. I think we can be happy and grateful that the program works so well with Windows 10.

WaveEdit: a cross-platform, open source waveform editor for the Synthesis Technology E352 Cloud Terrarium and the E370 Quad VCO

WaveEdit is a free tool on PC/Mac/Linux that allows powerful creation and editing of wavetables for the E352 and E370 VCOs. Using standard WAV formats, the editor includes a full toolbox of shortcuts. An audio Preview is available to audition the waves before loading into the module.

This revolutionary new synthesizer uses 16-bit sampled and synthesized waveforms for optimum sound quality. The friendly user-interface and parameter structure of the Kawai K series has been retained, and new functions and features added to increase the K4r is music making power.

The K4 is a 61 key touch-sensitive synthesizer equipped with a DMS (Digital Multi Spectrum) tone generator capable of up to 16 notes of polyphony when set at two Sources per tone. The K4r is a 19 inch, 2U rack-mount module version.

256 high quality internal waveforms

The K4/K4r has 96 CD (Digital Cyclic) waveforms composed of as many as 128 harmonics, and a total of 160 PCM waveforms, for a total of 256 waveforms. Because the K4/K4r’s internal waveforms are reproduced using 16-bit quantization, noise and distortion are virtually inaudible.

DRUM Section

The K4/K4r has its own DRUM Section which can be controlled independently of SINGLE Patches or the eight Sections of a MULTI Patch. The 61 keys from C1-C6 on the keyboard may be assigned freely to produce these tones.

Internal EFFECT (K4) and mising capability (K4r)

The K4 has 16 types of internal effects, including Reverb, Delay and Overdrive, etc.. In MULTI PLAY, the depth of the effect may be set for each tone.

Realistic touch response

The K4/K4r has the feeling of an acousic piano keyboard, a feature which has made the Kawai K series so popular. In addition, Velocity, Aftertouch, Release Velocity and Keyboard Scaling features allow the expression of the most minute touch on the keyboard.

MULTI PLAY capability

Eight SINGLE tones may be reproduced by the DMS tone generator, freely combining the Layer, Velocity Switch and Split functions, enabling far more beautiful layered and split sounds than have ever been possible before.

Variable Multi-Timbral capability

In the MULTI PLAY mode, each tone may be set to a specific MIDI channel, allowing the K4/K4r to function as though it were eight MIDI tone generators (or nine with the DRUM Section). The Variable Multi-Timbral function also allows the voices of each Section to be played simultaneously.

INDIVIDUAL OUTPUT function (K4r only)

The K4r is equipped not only with two stereo output jacks, but with six separate output jacks as well to allow the connection of external effects units to create high quality sound.

LINK

Eight patches from those in the unit may be selected and stored together. This function is used, for instance, when multiple tones are to be used in sequence. When arranged in the order in which they are to be called up, the operator may easily change tones from one to the next while playing.

MIDI

By connecting an external MIDI device to the MIDI jack, the K4/K4r may be used as a tone generator module with drums, or to control the external MIDI device.

Card

A card permits an increased number of tones to be placed in memory. One card can hold 64 SINGLE Patches, 64 MULTI Patches, the DRUM Section and EFFECT or OUTPUT Settings.

A great resource for new and seasoned S‑50 / S‑550 / S‑330 / W‑30 sampler owners. A lot of interesting information is here along with DIY’s, Start-Up Disks and Free Sample Disks. In the late 1980’s, the S‑50 and S‑550 were two of the hottest samplers on the market because of great sounds, free sample libraries and the ability to connect a color monitor and a mouse for easy menu navigation. These samplers can be found for incredibly low prices on eBay and elsewhere. I purchased a near mint W‑30 for only $35. It’s now an indispensable keyboard in my studio and a real workhorse. Granted… this is old technology by today’s standards, but still… great sounding instruments!

Year Of Release: 1987 Retail Price: $3,495 USD

Roland S-550

A rack-mounted version of the S-50 came in the form of the S-550, which also had double the sample memory (1.5 Mb) and more importantly, real-time filters (called time-variant filters) derived from LAS-type synthesizers like the D-50. A slimmed down, consumer friendly version of the S-550 was also available as the S-330. Both rack-mounts support the DT-100 Digitizer Tablet and an external CRT monitor. The S-50/S-550 has been used by Vangelis, Duran Duran and Jimi Tenor.

Eye found the old Nubus card and breakoutbox for rebuilding Radius VideoVision Broadcast System

not that need it for video anymore yet figure may as well use the extra audio/video i/o with 442 system

have all the drivers and software on active working SCSI hard drives

Set the Wayback machine for the mid 1990’s and read this! Radius VideoVision Telecast SP ™ Nubus running Radius Edit™ oN a Apple 7100/80 with a FWB SCSI Jackhammer™, Blue ICE™ and Sonnet Crescendo™ CPU accelerator cards.

Within the Radius Telecast setup, you would be able to edit your video projects right on the desktop with professional results! Gone were the days of trying to cut your film with white, cotton Mickey Mouse gloves on a Steenbeck® flatbed editor and splicing it together with Scotch or splicing tape or, paying exuberant cost for your negative and answer print of you’re film!

A VideoVision Telecast was a professional video editing, production station in a box as long as you already had an Apple 7100/80 (later the Apple 9600/350 series machine with PCI-Bus architecture) or, Radius 81/110 (Mac clone) with plenty of RAM, an FWB Jackhammer SCSI card and a couple of StudioArrays for storage. The software included with the Telecast was Adobe Premiere, Adobe After Effects (Adobe just acquired AE from CoSA at the time), VideoFusion and my favorite editing tool of choice even over Media Composer, Radius Edit! You would then just connect a Sony Betcam SP or S-Video deck to the dedicated computer and you’re off to spin some serious video sorcery!

Reflecting on this, I remember that I was one of the more popular filmmakers on my block simply because I owned (I now own two) a Radius VideoVison SP Telecast ™ system. Everybody that came to me was some sort of budding filmmaker, crawling out of the woodwork, just itching to get their movie projects on to and edited on this thing, the fact that you could now edit your film right on the desktop in a stable work environment got me chopping at the bit to be a filmmaker!

Yes, Avid® did get to the market first, in the mid eighties within the desktop environment. Fully integrating their 1000XL, Media Composer® system with an Apple Macintosh® computer but, who could afford the astronomical price tag $70,000.00? Funny that’s the same price that the Red One Dragon™ camera would cost you these days with all the accessories and a decent set of glass!

I don’t think I mentioned that I run my Radius on OS 9, oh yeah! Also, I have the latest and last seed package ever to roll out of Digital Origin for the Telecast before the company went belly-up. If you by chance are still running a Radius VideoVision Telecast™ on a Nubus or PCI based system and need some support to get it up and running on OS 9, I can shoot you my extensions and control panels list as well as my working setup. Also, I have Nubus and PCI drivers for Radius, FWB JackHammer™, SledgeHammer™ products as well.

If you’ve ever been to Fantasy Studios in Berkeley, California then, you can fully appreciate this. In the bowels of Fantasy there are many ancient Apple computer systems that run older OS’s and software primarily used for reading older audio, sound and movie files.

Musical Theory,
Base 60 Number System,
and Gods of Ancient Sumer
by Ernest G. McClain

Musical Theory and Ancient Cosmology by Ernest G. McClain

In ancient Mesopotamia (Sumer, Sumner), music, mathematics, art, science, religion, and poetic fantasy were fused. Around 3000 B.C., the Sumerians simultaneously developed cuneiform writing, in which they recorded their pantheon, and a base-60 number system. Their gods were assigned numbers that encoded the primary ratios of music, with the gods’ functions corresponding to their numbers in acoustical theory. Thus the Sumerians created an extensive tonal/arithmetical model for the cosmos. In this far-reaching allegory, the physical world is known by analogy, and the gods give divinity not only to natural forces but also to a “supernatural,” intuitive understanding of mathematical patterns and psychological forces.

The cuneiform mathematical notation, invented by Sumer, was fully exploited by the virtuoso arithmetical calculations of Babylon, politically ascendant in the second millennium. The notation employs few symbols, which are distributed in patterns easily understood by the eye. Thus, few demands are made on memory. In Mesopotamia, mythology took concrete form; for example, important activities of the gods can be read as “events” in a multiplication table notated as a matrix of Sumerian bricks. Classical Greece abstracted all of the rational tonal concepts embedded in this Sumerian/Babylonian allegory for two thousand years, simply waiting to be demythologized. Moreover, because the religious mythologies of India, China, Babylon, Greece, Israel, and Europe use Sumerian sources and numerology, theology needs to be studied from a musicological perspective.

If science is conceived of as knowledge and philosophy as love of wisdom, then the invention of musical theory clearly is one of the greatest scientific and philosophical achievements of the ancient world. When, where, and how did it happen?

Assuming that Cro-Magnon man processed sound with the same biology we possess, humans have shared some fifty thousand years of similar auditory experiences. Musical theory as an acoustical science begins with the definition of intervals, the distance between pitches, by ratios of integers, or counting numbers, a discovery traditionally credited to Pythagoras in the sixth century B.C.

Not until the sixteenth century A.D., when Vincenzo Galilei (Galileo’s father, an accomplished musician) tried to repeat some of the experiments attributed to Pythagoras, was it learned that they were apocryphal, giving either the wrong answers or none at all. Today, as the gift of modern archaeological and linguistic studies, our awareness of cultures much older than that of Greece has been phenomenally increased; this permits us to set aside the tired inventions about Pythagoras and tell a more likely story, involving anonymous heroes in other lands.

Cuneiform, considered the world’s first writing,
developed among the merchants of Sumer.
A triangular stylus was pressed into hand-sized slabs of wet clay,
then the clay was baked.
Most cuneiform tablets record commercial transactions.

My story is centered in Mesopotamia. It demonstrates how every element of Pythagorean tuning theory was implicit in the mathematics and mythology of that land for at least a thousand years, and perhaps two thousand, before Greek rationalists finally abstracted what we are willing to recognize as science from its long incubation within mythology.

What seems most astounding in ancient Mesopotamia is the total fusion of what we separate into subjects: music, mathematics, art, science, religion, and poetic fantasy. Such a fusion has never been equaled except by Plato, who inherited its forms. Socrates’ statement about the general principles of scientific studies in book 7 of Plato’s Republic, with the harmonical allegories that follow directly in books 8 and 9, guides my exposition here. The Mesopotamian prototypes to which they lead us fully justify Socrates’ treatment of his own tale as an “ancient Muses’ jest,” inherited from a glorious, lost civilization. Scholars who have become too unmusical to understand mankind’s share in divinity, as Plato feared might happen, still can lean on him for understanding, for all of his many writings about harmonics and music have survived. (I must suppress here, for reasons of space, the extensive harmonical allegories of the Jews, whose parallel forms infuse the Bible with related musical implication from the first page of Genesis to the last page of Revelation.)

Music was as important in ancient India, Egypt, and China as it was in Mesopotamia and Greece. All these cultures had similar mythic imagery emphasizing the same numbers, which are so important in defining musical intervals; this raises doubts about whether any people ever “invented” acoustical theory. For instance, in any culture that knows the harp as intimately as it was known in Egypt and Mesopotamia, its visible variety of string lengths and economy of materials (strings require careful and often onerous preparation) encourage builders, as a sheer survival strategy, to notice the correlation between a string’s length and its intended pitch.

Similarly, in China, where by 5000 B.C. the leg bones of large birds, equipped with tone holes appropriate for a scale, appear as paired flutes in ritual burials, the importance of suitable materials conditioned pipemakers to be alert to lengths. The basic ratios could have been discovered many times in many places, more likely by loving craftsmen and practitioners than by philosophers. Certainly, the discovery came no later than the fourth millennium B.C., before even the first Egyptian dynasty was founded or the Greeks had reached the Mediterranean shore.

A NEWLY EMERGING PERSPECTIVE.
In the fourth millennium B.C., the Sumerians, a non-Semitic people of uncertain origin, developed a high civilization in Mesopotamia, now the southern part of Iraq. For reasons that have been vigorously argued but remain unclear, they developed a base-60 number system. Waiting to be recognized within it–and in ways obvious to any scribal adept, although invisible to the illiterate–were the main patterns of harmonical theory that appear later in India, Babylon, and Greece. Sumerian tombs of this early period yield a harvest of harps, lyres, and pipes, and the literature surviving on clay tablets abounds in elaborate hymns.

In the cuneiform writing of the Sumerians, which was invented concurrently with the base-60 number system, the pantheon of deities is rationalized by assigning to the high gods the base-60 numbers that, as we shall see, encode the primary ratios of music. The glyph, or symbol, for heaven or star, followed by the appropriate number, functions as a “god nickname.” (The numerical values of the deities are given in Budge 1992.) The numbers reveal their significance in triangular arrays of pebble counters.

Furthermore, in the mythology of their religion, the responsibilities and behavior of the gods correspond with the functions of the god numbers in base-60 acoustics. Sumerian cosmology is grounded in the metaphorical copulation of the male A and female V numerical arrays, from which the Greek “holy tetraktys” is abstracted.

For example, the head of the pantheon and father of the gods is the sky god An (the thanAnu), god 60, written in cuneiform as an oversize 1 sign. Because base-60 numbers enjoy potentially endless place value meanings as multiples or submultiples of 60 (like the unit, 1, in decimal arithmetic), An = 60 (written as 1) functions as the center of the whole field of rational numbers. In mathematical language, An is its geometric mean, being the mean between any number and its reciprocal.

Anu/An, therefore, is essentially a do-nothing deity, as he was later accused of being-, a reference point, perfectly suited to represent simultaneously the middle band of the sky, the center of the number field, and the middle, reference tone (the Greek mese) in a tuning system. He was fated to be deposed by more active leaders among his children, as harmonical logic focused more clearly on structure and sheer virtuosity in computation became subordinated to deeper mathematical insight.

Theology, from its birth as “rational discourse about the gods” and in many later cultures influenced by Sumer, is mathematical allegory with a deeply musical logic. Tuning theory today remains a fossil science with no change at all in its basic parameters–structured by the gods themselves in numerical guise–since it premiered in Sumer about 3300 B.C.

To glimpse this new vision requires that we lay aside our algebra, our computers, and our pride in rational superiority and represent numbers to ourselves as the ancients did: concretely. We must learn to do musical arithmetic with a handful of pebbles in a triangular matrix, as the Pythagoreans teach us, imitating the pattern of bricks in the Sumerian glyph for mountain.

Then, like Socrates, we must show ourselves the harmonical implications of that arithmetic with a circle in the sand, for that circle is the cosmos, viewed as endlessly cyclical, like the tones of the musical scale.

In what follows I am presenting Mesopotamian arithmetic as Plato still practiced it in the fourth century B.C., studying his mathematical allegories for clues to earlier examples. Plato is the last great harmonical mythographer of the European world; never again did a major philosopher so thoroughly ground his thinking in music.

In retrospect, decoding Sumerian-Platonic harmonics proves astonishingly simple. Anyone, even a child, who can count to ten and sing or play the scale can make self-evident the scale constructions that once modeled the cosmos.

Because 60 is integrally divisible by 2, 3, 4, 5, 6, 10, 12, 15, 20 and 30, base-60 arithmetic can correlate many subsystems, allowing fluent manipulation of fractions. This very early mastery of fractions ensured adequate arithmetical definition of pitch ratios–presumably as string-length ratios on early harps, approximate length ratios on the flutelike panpipes, or tone-hole ratios on the aulos–no matter how many tones are involved and whether pitch patterns rise or fall.

About 1800 B.C., the Babylonians became politically ascendant and reorganized the Sumerian pantheon, keeping its god numbers and related mathematical terminology. They developed base- 60 computation to a level of arithmetical virtuosity not equaled in Europe until about A.D. 1600 and not understood in modern times until the middle of our own century (see Neugebauer 1957). Not until 1945, when Neugebauer and A. Sachs published the translation of cuneiform tablet YBC 7289 from the Yale collection, did the world learn that ancient Babylon (1800-1600 B.C.) possessed a base-60 formula for the square root of 2 accurate to five decimal places (1.41421+), or the formula for generating all Pythagorean triples (a triangle with sides of 3, 4, and 5 units is merely an example) a thousand years before Pythagoras explicated the first one.

The Greeks, still thinking in terms of Egyptian unit fractions (so that a descending whole tone of 8:9, for instance, was constructed by laboriously adding to the reference length 1/8 of itself), would have been astonished to learn that the Egyptians, whom they revered, had like themselves been far surpassed in computational facility by an ancient neighbor.

The paucity of surviving Sumerian mathematical texts requires scholars to make many inferences from later Babylonian survivals, and much Sumerian literature remains untranslated or inaccessible. Thus, as further linguistic evidence becomes available, the story I tell here will require revision, becoming more certain in dating, clearer in meaning, and richer in detail.

To look ahead in history and see the persistence of Sumerian/Babylonian methods, Ptolemy, in the second century A.D., in the Harmonica, recorded all of the some twenty Greek tunings known to him with sexagesimal (base-60) fractions. Between about 500 B.C. and A.D. 150, Babylonian and Greek astronomy thrived on base-60 computation. It was still used by Copernicus in the fifteenth century and endures in modern astronomy. The Chinese calendaris still reckoned by 60s. Astronomy, however, as the science of precise measurement that it later became, “was practically unknown in ancient Sumer; at least as of today we have only a list of about twenty-five stars and nothing more” (Kramer 1963).

HOW BASE-60 SURVIVES IN TIME MEASUREMENT
Analog clocks and watches equipped with rotating hands for hours, minutes, and seconds are living fossils of the Sumerian arithmetical mind-set.

a. Numbers have visible and tangible markers on the dial (representing the fixity of the recurring temporal cycle), restricting burdens on memory and permitting operations to be reduced to counting and adding.

b. Sixty can be conceived of, when we please, as a large unit (one rotation of the second or minute hand), conversely giving the small unit the implication of 1/60.

c. The large unit, alternately, can be conceived of as a higher power of 60 (correlating the simultaneous rotations of both second and minute hands), for 60 X 60 = 3,600 seconds is also one hour, conversely giving our small unit the implication of 1/3,600.

d. Twelve hours constitutes a still larger unit (one rotation of the hour hand) of 12 x 60= 720 minutes, and 12 x 3,600 = 43,200 seconds, conversely giving the smallest unit the implication of 1/720 or 1/43,200.

e. We avoid confusion between these alternate arithmetical meanings the same way the Sumerians did, namely, by remembering the context of the questions we are trying to answer.

f. The existence of alternative ways of expressing a unit, as in the examples above, indicates and emphasizes the importance of reciprocals.

Musicians, following Plato, still project their tones into a circle that eliminates cyclic octave repetitions (Plato, in the Timaeus, insists that God makes only one model of anything). Thus today, using our modern, equal-tempered scale, we can identify any musical interval as some multiple of a standard semitone, to the envy of calendar makers, who, having to deal with the irregularities of days, months, and years, are jealous of our perfect twelve-tone symmetry. But the nearest approximation of our twelve-tone, equal-tempered scale in small integers remains that provided by ancient base-60 arithmetic.

SUMERIAN NUMBERS Sumerian numbers were impressed on small clay tablets with a stylus, at first round,later triangular, held slanted for some numbers and vertically for others. Numbers from 2 to 9 were built up by repetitions of the unit, made with the edge of the stylus. A 10 was imprinted with the end; a 60 was made as a large 1 by pressing the stylus more firmly into the clay. The equation 60 X 60 = 3,600 was scratched in as a circle (see vander Waerden 1963). Only a few symbols were needed, and repetition made them easy to decode, minimizing burdens on memory. The idea of a number was actually embodied in the strokes required to notate it.
Computation was made easy by tables of “reciprocals, multiplications, squares and square roots, cubes and cube roots, …exponential functions, coefficients giving numbers for practical computation,…and numerous metrological calculations giving areas of rectangles, circles” (Kramer 1963). Many copies of these tables have come down to us.

The standard multiplication tables pair each number with its reciprocal and give special prominence to the favored subset of “regular” numbers, whose prime factors are limited to 2, 3, and 5 (larger prime factors necessarily lead to approximations in the reciprocals). “Regular numbers” up to 60 are shown with their reciprocals, transcribed, for instance, so that the reciprocal of 40/60 = 2/3 reads 1,30, meaning 90/60 = 3/2. Notice that only the most important fractions of 60 are deified (1/6, 1/5, 1/4, 1/3, 1/2, 2/3, and 5/6). The tone names are nearest equivalents in modern notation. Several values require three sexagesimal “places” (indicated by commas); auxiliary tables freely employ six, seven, and even more places.

SUMERIAN SYMMETRY OF OPPOSITES

A telling clue to the psyche–of Sumerians, of Plato, and of ourselves–is affection for the symmetry of opposites. Inverse, or bilateral, symmetry conditions base-60 computation, as it conditioned Platonic dialectics. (“Some things are provocative of thought and some are not…Provocative things…impinge upon the senses together with their opposites.” Republic 524d) When facing a mirror we exhibit to ourselves, with varying degrees of perfection, this symmetry of left/right opposites across an imaginary “plane of reflection.”
The old-fashioned scale, or balance beam, epitomizes this notion. The balance owes its functioning to gravity, but its appeal to us, its attractiveness, is due to our ear, which in addition to being the organ of hearing is also the personal organ of balance. Our empathic human feelings for the balance beam affect the inverse, orbilateral, physical symmetry because of the experience of balancing our own bodies, an activity dependent on the ear, not the eye. All of the computations presented later will be aligned in this basic symmetry, with Anu/An = 60 (meaning 1) on the balance point. Sumerian art greatly elaborates this symmetry of opposites.

THE DEIFICATION OF TONE NUMBERS

The deified Sumerian numbers, taken over by Babylon, are 10, 12, 15, 20, 30, 40, and 50, all fractional parts of “father” Anu/An = 60, head of the pantheon. Their fractional values and god names are indicated here with a brief description of their mythological functions.

Anu/An, 60, written as a large 1, “father of the gods” and earliest head of the pantheon, is any reference unit. He is equivalent in our notation to 60/60 = 1, where he functions, according to modern concepts, as “geometric mean in the field of rational numbers.”

Enlil, 50 (5/6), “god on the mountain” possessing fifty names, is mankind’s special guardian and was promoted to head the pantheon circa 2500 B.C. Enlil deities in base 60 what the Greeks knew as the human prime number, 5, in their base-1O harmonics. By generating major thirds of 4:5 and minor thirds of 5:6, he saved Sumerians tremendous arithmetical labor, as we shall note in due course.

Ea/Enki, 40 (2/3), “god of the sweet waters” and perhaps the busiest deity in Sumer, “organizes the earth,” including the musical scale. He deities the divine prime number, 3, in the ratio of the musical fifth 2:3, the most powerful shaping force in music after the octave. (Notice that the trio of highest gods (40, 50, 60) defines the basic musical triad of 4:5:6 (do, mi, sol, rising, and mi, do, la, falling). The ratio 4:5 defines a major third and the ratio 5:6 defines a minor third, taken either upward ordownward within the matrix of the musical octave.)

Sin, 30 (1/2), the Moon, establishes the basic Sumerian octave matrix as 1:2 30:60.

Shamash, 20 (1/3), the Sun, judges the gods.

Ishtar, 15 (1/4), is the epitome of the feminine as virgin, wife, and everybody’s mistress.

Nergal, 12 (1/5), is god of the underworld.

Bel/Marduk, 10 (1/6), the biblical Baal, originally was a minor deity but eventually became head of the Babylonian pantheon in the second millennium B.C. He inherited all the powers of the other gods, including Enlil’s fifty names, in a giant step toward a”Pythagorized” monotheism built on the first ten numbers.

GREEK HARMONICAL PRINCIPLES IN SUMERIAN ARITHMETIC

Here are the principal arithmetical symmetries of base-60 Sumerian harmonics, summarized in the inverse “heraldic” symmetry displayed above but expressed as modern fractions. Every tone in the scale will be found to participate in numerous god ratios,and all other ratios are their derivatives via multiplication (which is what Plato means by “marriage” in his elaborate metaphor in the Republic). All of the harmonical concepts in my analysis, however, are Greek. Plato’s formula for this particular construction can be found in the Republic, book 8; his discussion of general harmonical principles is in the Timaeus.
All pitch classes generated by the prime numbers 2, 3, and 5, up to the index of 60, are represented here (fig. 9). Remember that all doubles are equivalent, so that 3, 6, 12,and 24 define the same pitch as 48, for example.

a. Tones are defined by numbers.

b. The significance of a number lies only in its ratio with other numbers.

c. Numerosity is governed by strict arithmetic economy. Because Sumerian double meanings were assumed, the numbers 30, 32, 36,… are in smallest integers for this context. This economy is obscured somewhat by writing ratios as fractions; mentally eliminate the superfluous reference 60s.

d. Every number is employed in two senses, as great and small, displayed here as reciprocal fractions.

e. The double meanings of great and small require the basic model octave to be extended across a double octave from 30/60 = 1/2 to 60/30 = 2.

f. Tones are grouped by tetrachords (that is, in groups of fours) whose fixed boundaries always show the musical proportion 6:8 = 9:12, defining the octave (6:12 = 1:2), the fifth (2:3, that is, 6:9 and 8:12), and the fourth (3:4 or 6:8 and 9:12).

Notice how the arithmetic mean 9 and the harmonic mean 8 establish perfect inverse symmetry and define the standard whole tone as 8:9. These ratios define the only fixed tones in Pythagorean tuning theory, and they are invariant. Pythagoras reputedly and plausibly brought this proportion home from Babylon in the sixth century B.C. In base 60, these “framing” numbers necessarily are multiplied by 5 into 30:40 = 45:60.
Notice that Ea/Enki, god 40, defines these frames (D:A falling and G:D rising) in his double role as 40:60 and 60:40 and thus literally “organizes the earth” (as represented by the string) into do, fa, sol, do, harmonic foundations of the modern scale.

g. The Enlil = 50 tones of pitch classes b and f always belong to the opposite scale, for the god shares these tones with 36 (that is, 30:36 = 50:60 and 30 and 60, “beginning and end,” coincide); thus, Enlil is free to supervise the system by reminding us of the symmetry of opposites.

Enlil’s promotion to head the pantheon possibly symbolizes this insight. He plays a very active role, also generating several intervals that actually reduce numerosity, whereas the primal procreator, Anu/An = 60, a do-nothing deity of little account in Sumer and Babylon, remains purely passive.

Platonic dialectics, however, emphasize anew the importance of an invariant t4 seat in the mean,” thus turning Anu/An’s passiveness as geometric mean into the greatest possible Socratic virtue as “the One Itself.”

h. The falling or descending version of this scale, as notated is in our own familiar major mode. It is more commonly notated one tone lower, on the white keys of the C octave. The rising scale on the right, its symmetric opposite, is the basic scale of ancient Greece, India, and Babylon. It is more simply notated one tone higher, on the white keys in the E octave.

My choice of D as reference pitch is dictated by the necessity of showing opposites simultaneously, in the Sumerian normative arithmetical habit that Plato later required of his students in dialectic. Future philosopher-guardians in idealized cities needed to become expert in weighing the merits of contradictory claims, requiring the ability to see opposites simultaneously. Music provided the opportunity to do this, par excellence, and so childhood training began with it.

AN OVERVIEW OF CALENDAR AND SCALE
To coalesce the musical opposites shown above into one Sumerian/Platonic overview, eliminating all octave replication and laying bare the irreducible structure (“God’s only model”), we need only project these tones into the same tone circle.

From Plato’s mythology (in the Critias) come “Poseidon and his five pairs of twin sons”, aligned in perfect inverse Sumerian symmetry across the central vertical plane of reflection. (Poseidon, at twelve o’clock, Greek successor to the water god Ea/Enki, is self-symmetric, being both beginning and end of the octave no matter whether we traverse it upward or downward.) These eleven tones constitute the only pitch class symmetries up to an index of 60.

But to coalesce opposite fractions so that the numbers–like the tones–show the same ratios when read in either direction, we must expand the numerical double 1:2 into 360:720. If we confine ourselves to three-digit numbers, there is, in addition to Poseidon’s ten sons, only one other pair of symmetric numbers, namely, 405 and 640 (since 405:720 = 360:640). These are notated here as C and E to indicate their very slight and melodically insignificant difference from c and e. This microtonal “comma” difference of 80:81, barely perceptible in the laboratory and then only by a good ear, was taken by the Greeks as the smallest theoretically useful unit of pitch measure and is approximately 1/9 of their standard whole tone of 8:9. The whole-tone interval between A and G invites similar subdivision, and symmetry requires a point directly opposite our reference, D. This locus is defined by the square root of 2, lying beyond the ancient concept of number, and so we must search for an approximation.
A musically acceptable candidate (its error is actually less than a comma) now appears at a-flat = 512, or, alternately, g-sharp = 512, only slightly askew our ideal value and with the “god ratio” of 4:5 with C or E.

Plato’s Poseidon and his ten sons are shown again, together with the new symmetry pair C/E and the alternate a-flat/g-sharp pair (one of which is always missing in the 360:720 octave). My vertical pendulum now swings gently back and forth to either side of six o’clock as the numbers are read alternately in rising and falling scale order (that is, as great and small).

At 512, where a-flat is not quite equivalent to g-sharp, the ancients had little choice but to accept this arithmetical compromise with perfect inverse symmetry.

How did they rationalize such a complicated, inverse symmetry, one ultimately defeated because of the compromise? Remembering the quite ancient correlations of scale and calendar, let us apply imagination to their problem.

This base-60 model can be imagined as an appropriate correlate to the lunar calendar of Sumer and Babylon, as it later became the map of an idealized circular city in Plato’s Laws, calendar and musical scale being assumed to have a similar cosmogony. Notice the following correspondences:

a. The basic seven-tone scale requires the thirty digits in the 30:60 octave, and 30 is deified as Sin, the Moon, and the basic octave limit.

b. The two opposite seven-tone scales and the symmetrically divided tone circle correspond with Sumer’s two agricultural seasons, in which irrigation during the dry summer complemented the rainy winter harvest.

c. In the octave double between 360 and 720, which coalesces opposites, there are 360 units to correspond with the schematic calendar count of 12 x 30 = 360 days. (Eventually, astronomers in India and Babylon defined these units as tithis, meaning 1/360 of a mean lunar year of 354 days, hence slightly less than a solar day. Greek astronomers eventually defined the same 360 units geometrically as degrees. Neither development is relevant to ancient Sumer.)

d. Tonally acceptable but acoustically inaccurate semitones, alternately small (24:25) and large (15:16), correspond with the lunar months embodied in ritual, alternating between 29 and 30 days.

e. Between a-flat = 512 and g-sharp 512 (in the opposite sense), a gap corresponds with the excess of a solar year over 360 and the defect of a lunar year of 354 days from 360.(Five and a quarter extra solar days are about a 1/69 of 360, while the gap in the reduced comma is actually about 1/60 of an octave, a remarkable near-correspondence.)

Because any successful agricultural society must find some way to accommodate lunar, solar, ritual, and schematic cycles with the growing cycle, we need not suppose that Sumerians or anyone else ever really believed the year contained 360 days. Only a musicology dedicated to numerical precision and economy finds 720 days and nights (that is, 360 days and 360 nights) cosmogonically correct.

MATRIX ARITHMETIC

All of the tonal, arithmetical, and calendrical relations discussed above are coincidences. They exist among base-60 numbers whether or not anyone is aware of them, mainly because 60 is divisible by three prime numbers, 2, 3, and 5, and no others, and 60 is being used in the way we use a floating-point decimal system.

If Sumerian mythology did not offer persuasive evidence that Sumerians were conscious of tonal implications, then their establishment of a base-60 system, which included such perfect models for a lunar-oriented culture and for Pythagorean harmonics two thousand years later, would be pure serendipity, meaning that it resulted from “the gift of finding valuable or agreeable things not sought for.” But the most interesting evidence for Sumerian harmonical self-consciousness is yet to be shown via Plato’s kind of triangular matrices, functioning as “mothers” in harmonical arithmetic.

In Plato’s Greece, the harmonical wisdom of Babylon and India was transformed into political theory. Men now acted out the roles once assigned to gods. Plato’s four model cities–Callipolis (in the Republic), Ancient Athens and Atlantis (both in the Critias),and Magnesia (in the Laws)–were each associated with a specific musical-mathematical model, all generated from the first ten integers. All are reducible to a study of four primes: 2, 3, 5, and 7.

In the Republic and Laws, idealized citizens–represented as number–generate only in the prime of life. For Plato, this means that 2 never really generates anything beyond the model octave 1:2, for this “virgin, female” even number–with all of its higher powers–designates the same pitch class as any reference 1.(Multiplication by 4, 8, 16,… generates only cyclic identities, different octaves of tones we already possess. They are Plato’s “nursemaids,” carrying tone children until they are old enough to “walk” as integers; hence, as he says, his “nurses” require exceptional physical strength.)

The multiplication table for the 3 x 5 male odd numbers, however, generates endless spirals of musical fifths (or fourths) and thirds; within the female octave 1:2, new pitches are generated at the same invariant ratios. The Greek meaning of symmetry is to be in the same proportion. Thus, a continued geometric proportion (like 1, 3, 9,27,…or 1, 5, 25,…) constitutes “the world’s best bonds,” maximizing symmetry, which is obscured by mere appearances when these values are doubled to put them into some preferred scale order. The multiplication table for 3 x 5 graphs multiple sets of geometric tonal symmetries (Plato’s only reality) as far as imagination pleases.

Greece inherited its arithmetical habits from Egypt, including an affection for unit fractions in defining tunings (the ratio 9:8 was thought of as “eight plus one-eighth of itself,” and so on). It awoke to number theory only when it became acquainted with Mesopotamian methods. Thus, the travels of Pythagoras, whether legendary or not, played an important role. Those methods apparently were new enough in Plato’s fourth century B.C. to invite his extensive commentary, yet old enough so any novelty on Plato’s part was absolutely denied by Aristoxenus (fl. circa 330 B.C.) within fifty years.

Plato is responsible for an astonishing musical generalization of the base-60 tuning formula as 4:3 mated with the 5. His 3, 4, and 5 correspond with Sin = 30, Ea = 40, and Enlil = 50 and remind us that all tones are linked by perfect fourths, 4:3, which define possible tetrachord frames, or by perfect thirds, 4:5. The last Pythagorean who really understood Platonic “marriages” may have been Nicomachus in the second century A.D.; he promised an exposition but none survives.

BABYLONIAN REORGANIZATION OF THE PANTHEON

In the second millennium B.C., the Babylonians reorganized the inherited Sumerian pantheonin a way that very strongly points toward its Pythagorean future. To avoid destruction by Enlil, who is disturbed by their confusion and noise, the gods reorganize under the leadership of Marduk, god 10, the biblical Baal, to whom all the other gods cede their powers.

Herein lies a beautiful reduction of Sumerian expertise with reciprocal fractions to a more philosophical overview of harmonics as being generated exclusively by the first ten integers (Socrates’ “children up to ten,” in the Republic, beyond which age he doubted citizens were really fitted for ideal communities).

To celebrate their survival after Marduk defeats the female serpent Tiamat, sent to destroy them, the gods decree him a temple; the bricks require two years (2 x 360 = 720) to fabricate. This mythologizes 720, the Sumerian unit of brick measure, and the smallest tonal index able to correlate seven-tone opposites into a twelve-tone calendrical octave. When Marduk’s tonal/arithmetical bricks are aligned in matrix order, we see that the general shape of his temple (with an index of 720) is an enlarged form of Enlil’s temple (with an index of 60); Enlil now confers his fifty names on Marduk. This temple makes Marduk’s face shine with pleasure, we are told.

Let me conclude our discussion of Marduk’s victory over the dragon, Tiamat.

‘GREAT DRAGON’ TUNING
It is now a normal part of a child’s musical education to learn to view the scale as a spiral of musical fifths and fourths, as they are actually tuned–for the convenience of the ear–and to be shown those tones in a tone circle. That up-and-down, alternating cycle of pitches inspires, I propose, the dragon and great serpent lore of ancient mythology.

Serpentine undulations are visible to any harpist in the lengths of successive strings when taken in tuning order (as they still necessarily are), and the undulations can be seen in any set of pitch pipes when similarly aligned, as in China. Because the same tone numbers function reciprocally as multiples of frequency and of wavelength, they have the same double meanings today that they enjoyed in Sumerian times. It is entirely appropriate, therefore, to represent this spiral both forward and backward, simultaneously, with intertwined serpents.

In the mythological account, Marduk slays the dragon (which is presumably the continuum of possible pitches represented by the undivided string) by first cutting it in half to establish the octave 1:2. Further cutting presumably “sections” the other pitches. No numbers larger than Marduk’s–meaning 10–play any role in geometrical sectioning of the string.

This “serpentine” double meaning–rising and falling musical fifths and fourths–lies at the very heart of our consciousness of musical structure. Sumer did not hesitate to make the double serpent the center of symmetry, as on this steatite vase of Gudea, priest-king of Lagash circa 2450 B.C., where they are flanked symmetrically by gryphons.
Large and unwieldy numbers can be avoided if the 4:5 and 5:6 ratios introduced by Enlil are used to define the seven-tone scale (in which case all the numbers are of two digits). Used for the twelve-tone scale, his numbers need only three digits. Thus, in Sumer, Enlil= 50, base-60 deification of the human, male prime number 5, grossly reduces our computational labors from six-digit Pythagorean numerosity (in which a twelfth tone requires 311 = 177,147) to no more than three, and without noticeably diminishing melodic usefulness. Only the five central tones (CGDAE) from the Great Serpent appear. All other tones are owed to Enlil.
Historically, European music reintroduced this Just tuning system in the fifteenth century A.D. to secure perfect 4:5:6 triads for its new harmonies without exceeding twelve tones. The ancients probably loved it more for its arithmetical economy than for its triadic purity. Microtonalists today, equipped with a powerful new technology, are again searching for an effective employment of these ancient Sumerian god ratios.

The ultimate origins of music theory, as opposed to the Sumerian codification that I deduce here, remain lost in the far more distant past, like the origin of our sense for number. They are grounded in a common aural biological heritage, some of which we share with other animals, and are by no means dependent, as Aristotle noted, on precise numerical definition. As eminent contemporary musicologist William Thompson explained in our correspondence,

In adapting to our complex environment, our sensory ingestive systems have become…forgiving filters, enabling us to generalize….This, I’m convinced, is a product of very early adaptive behavior, a part of our survival good fortune…in that our neural system has developed myriads of networks which are overachievers when it comes to doing some simple jobs.

Socrates never believed in the possibility of perfect justice. The great aim of Plato’s Republic was to help readers become more “forgiving filters” for alternative cultural norms. There remains a certain fuzziness about a scientific definition of musical intervals, as there is about the Republic’s days and nights and months and years, and art has turned that into something for which we all can be grateful. Sumerian “overachievers”–and these “black-headed people,” as they called themselves, proved historically to be as aggressive as the great heroes they knew or invented–achieved a tremendous synthesis of cultural values. They challenge us to do as well.
