The Instruō cèis[2] is a fully analogue voltage-controlled ADSR envelope generator. The ADSR function generator is the model pioneered by theEast-coast mindset and is extensively used in subtractive synthesis patches. The cèis[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. cèis | siːs | noun (envelope) a containing structure or layer, a curve joining the successive peaks of a modulated wave Size 8HPDepth: 27mm Power +12V: 70mA–12V: 40mA Features 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 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
