Instruo Ceis 2 Eurorack Envelope Generator Module

The Instru cis[2] is a 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 cis[2] gives 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 brings 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
