The CMOS synth was also made famous by Stanley Lunetta of Sacramento who passed away on March 3, 2016.
His Lunetta Synth inspired the DIY synthesizer community. He used mainly 4000 series CMOS chips.
Experimentation really is the whole point. Learning what the different types of logic chips do, and making use of them in interesting ways.

Double Gate CMOS (DG)
Traditional CMOS technology is approaching physicial limitations was we approach the nanoscale regime.
One such solution is the double gate transistor, proposed in the 1980s.
“Multigate transistors are one of the several strategies being developed by CMOS semiconductor manufacturers to create ever-smaller microprocessors and memory cells, colloquially referred to as extending Moore’s law.”

Other possible solutions include SOI devices, Strained-silicon FETs and carbon nanotube FETs

(router)
DG 508 – 8-channel single-ended analogmultiplexer designed to connect

(NLC Statues)

In vintage synths the most popular of the 4000-series chips appear to be

the analog bilateral switches (4016, 4066), the analog multiplexer/demultiplexers

4051, 4052,4053, 4067) and the 4046 phase-locked loop (PLL). These allow the
routing of analog control signals.

The 4046 PLL was used in such machines as the OSCar.

Lots of these chips are logic gates:

Precautions
When DIYing with CMOS logic chips be careful of damage caused by static electricity. Ground yourself or use a static mat.Store them in conductive foam or foamed plactic wrapped in aluminium foil.

You must connect any unused chip inputs to either VDD/VCC (V+) or VSS (ground). All inputs must go somewhere, either directly or with resistor.
Inputs that goes off board should have a load resistor connected (1M resistor to ground).
This brings us to what are referred to as Pull-up Resistors and Pull-down Resistors.

Inputs must not exceed VDD and never apply a input signal to an unpowered CMOS circuit.

Pullup & Pulldown resistors
These are used a lot in CMOS circuits.
They define the default state of the input (whether or not the switch is open, closed or there is nothing connected to it).
For example, any spare gates can be tied together or connected to a fixed voltage, using a high value resistor (10k -100K) to either the Vcc voltage, (pull-up) or via a low value resistor to 0V (GND), known as pull-down. Unused inputs should never be left floating about.

This DIY modular synth system is very much in the “Luneta” style. Stanley Lunetta was a man I never met but who seems cool and was really interested in abusing CMOS logic chips to make sounds from them. It turns out this is a really great way to have a lot of fun making a horrible racket without spending much money. If you want 1V/Octave tracking, tempwrature compensation and other things that make tonal music possible, you are going to be disappointed. If you want to make sounds like a dying cyborg trapped in a meat grinder then you are in the right place!

The banana jacks are colour-coded for easy patching – consult article #000 for more in-depth explanations:

Red – output
Black – primary (data/audio) input
Yellow – CV input
Blue – Clock input
Green – Trigger input
White – Gate input

Every article contains a schematic, a perfboard layout, a drill template for a eurorack sized panel, as well as an explanation and analysis of the circuit. The explanation is a more general overview of the circuit, while analysis is generally a deeper investigation involving calculations. You don’t need to know the maths! Ignore it if you don’t care! There’s also a warts-and-all admission of mistakes I made so that you don’t have to repeat them. Honesty is the best policy. DIY includes lots of messing up. Everything runs off a simple 9-12V DC wall-wart type adaptor, and outputs signals that range from 0-5V.

Though I have designed these to be beginner friendly, I reccomend you first know how to read a schematic and how to lay out and build something on perfboard as well as on a breadboard. Neither of these are tough though, so don’t worry! You can also definitely use these projects to learn about all of those things, but ultra-simple projects to get your feet wet might make things go smoother. Don’t expect everything to go right the first time. Hunting down your mistakes is part of the fun! Have patience!

000 – Power Supply and System Overview

The only module you will use 100% of the time. It’s slightly dishonest to call it a power supply though, as really you use a DC wall-wart as the power supply, this is just a switch, an LED and a bus board.

There is also a general overview of the system, including the colour scheme for the banana jacks and what the general ethos of this DIY project is.

http://castlerocktronics.com/modular/ar … SQUARE.pdf
001 – 4xSQUARE

You can’t have a synth, modular or otherwise, without oscillators! But why have one when you can have four? This is a slight twist on popular 40106 oscilator bank, with very simple CV control of the oscillators added with diodes. Very low parts count, a nice easy build.

In the article we cover why it oscillates, as well as why the diode allows for pitch control and gating. On top of that, we figure out how to calculate the pitch of the oscillators and how to figure out where the gating effect of the diode kicks in.

002 – Output Mixer

The other thing you can’t not have is some way to get the sounds together on one cable and out to an amp or your computer. That’s exactly what this module is for, with a little added extra: built in overdrive! 4 channels that are summed together and stepped down to line-level so you don’t blow anything up & smooth, but gritty overdrive for when you want to get aggressive. Very nice when you have pulsing ambient drones going on.

In the article we cover op-amps as inverting amplifiers (and summing amplifiers), using op-amps on a single-rail power supply as well as decibels and how diodes in an op-amp’s feedback loop create clipping.
Your browser does not support the element. Sorry!

Some drones driving the inputs hard to bring out the overdrive.

003 – 4xLFO

Four square wave LFOs with little blinky lights to show you how fast they are going. Endless fun. Just don’t stare into them too long or you will hurt your eyes.

This article is very short as the insides of this module are just the same as 001 – 4xSQUARE, only with bigger capacitors. However, I ran into a few problems while making it, which I write about briefly, mainly to do with drilling and measuring out panels – both of which I ballsed up terribly…

004 – Dual Shift Register

Two deceptively powerful and useful little tools tucked in nice and tight on a small panel. Chain them together for a larger 8-bit register!

The article covers what shift registers actually are, a tiny sampling of their many uses and a look into a circuit building block that we’ll be getting very familiar with – the leading edge detector. There is also what I hope will be the last of my woes from working with acrylic for the front panel.

http://castlerocktronics.com/modular/ar … -_R-2R.pdf
005 – R-2R

R-2R is two “R-2R ladders” in a tight 6HP package. The four inputs act as a 4-bit digital-to-analogue converter that is perfect for generating stepped waveforms to drive oscillators as a CV source or to create more interesting sounds than the raw squarewaves everything has been putting out till now. It is basically a Digital-to-Analog converter

The article gets really tucked into DC analysis as we pick apart how and why the R-2R ladder works. You will be sick of Ohm’s law by the end of it, but you should also never have to read up about it again!
Your browser does not support the element. Sorry!

http://castlerocktronics.com/modular/ar … ivider.pdf
006 – Dual Divider

Another simple double dose module, pretty much just a chip wired up to jacks and LEDs. It is a very useful chip though: the 74HC393. This little guy has two “binary ripple counters” which are sometimes also called frequency dividers.

The article is a brief one, but we talk a bit about the history of the 7400 and 4000 series logic families and some of the things you can use your divider for.

Divider outputs into R-2R, which drives an oscillator for arpeggio-esque patterns. That oscillator is then run through the other divider for a fat 8-bit bass sound.
