Thread: What would you add to my rack?
The Doepfer A-141-2 is a good exemple of VCADSR.
A cool trick to do with a sequencer and a quantizer is to feed a 8 or 16 step sequence in the quantizer, select a scale in it that fit your original sequence, then transpose that sequence in semitons (directly from the sequencer or from another keyboard/midi track). Quantizer will maintain the "off" note in the selected scale so you will end with a very musical result.
Intellijel µscale, Penrose Quantizer are good option since you can program the scale you want on the little "Keyboard" panel
