cèis

cèis is a fully analogue, CV controllable ADSR envelope generator. The ADSR is a more traditional shapable voltage control voltage envelope used extensively in subtractive synthesis patches. The Cèis allows full voltage control over the 4 segment faders with multiple gate/trigger outputs for maximum versatility of a classic tool.
