The Instruō cèis[2] is an 8HP fully analogue voltage controlled ADSR envelope generator. The ADSR function generator is the model pioneered by the East-coast mindset and is extensively used in subtractive synthesis patches.
The cèis[2] gives you the ability to externally control the attack, decay, sustain, and release stages of the envelope while also emitting trigger and gate signals for each segment, offering maximum versatility from a classic tool.
This version[2] revision adds additional flexibility and control through a completely redesigned logic extraction circuit for the segment gates, envelope re-trigger input, and a precision throughput for voltage controlled slew limiter capabilities.
Features
- LED button for manual control and indication of output CV level
- Fader and CV control over all 4 segments
- Gate output per segment
- Fader LED for segment stage indication
- Gate/Trig modes which can force completion of the Attack duration when triggered
- Hold mode for sustain segment lock for CV slew use
- Combined trigger output which fires when there is a change in segment
- Variable envelope response shape from linear to exponential
