Instruo - Cèis


Cèis is a fully analog, CV controllable ADSR envelope generator. This module allows full voltage control over the 4 segment faders with multiple gate/trigger outputs for maximum versatility of a classic tool.




  • LED button for manual control and indication of output CV level
  • Fader and CV control over all 4 segments
  • Gate output per segment
  • LED faders for indicating segment stage when in use
  • Gate/Trig switch which forces completion of the Attack duration when triggered
  • Combined trigger output which fires when there is a change in segment
  • Variable envelope response shape from linear to exponential
