Original sentence: Some synths also could generate CV/Gate signals and be used to control other synths..
Edited sentence: A major difference between CV/Gate and MIDI is that in many analogue synthesizers no distinction is made between voltages that represent control and voltages that represent audio.Control Voltage is analogue and by extension infinitely variable.For this reason MIDI Pitch Bend uses 14 bits or 16,384 possible steps.In MIDI they are separate worlds and there is no easy way to have audio signals modify control parameters.Most MIDI control messages use 7 bits or 128 possible steps for resolution.One of the main advantages of CV/Gate over MIDI is in the resolution.Some synths also could generate CV/Gate signals and be used to control other synths.There are ways to send higher MIDI resolution through the use of RPN's and NRPN's however in practice this is often difficult.There is less likelyhood of hearing the zipper effect or noticeable steps in resolution over large parameter sweeps.This means audio signals can be used to modify control voltages and vice versa
