Doepfer comparator module - more useful than you think.

Jonathan64, 11.09.2013
When I first bought a modular synth I did not think I would have any use for a comparator, but as my patching became more complex and sophisticated I began to realise how useful this module can be. Uses include generating complex LFO or oscillator waves by using one oscillator to modiy another, or detecting a voltage level - for example from a staircase generator, effectively making a pulse counter! You can make complex envelopes from a couple of simple ADSR modules too. This module allows you to compare two voltages, one of which can be internally manually set, or both can be from external sources. I recommend the you-tube video from Raul's world of synths. He has produced a whole series on different modules in the Doepfer range, endorsed by the company and there are two or three on the A-167.
