Vortex Sound Research

Hi, been playing synths for a while now but never really looked into MIDI. Im getting the Behringer Model D soon to go with my NL2X and MicroKorg. To play the Model D, is it as simple as plugging a MIDI cable from one of these synths into the MIDI IN, and using the keys on the others to play? I know this is really basic stuff but its all new to me Thanks a lot
