Instruo - Ceis [2]

The Instruō cèis[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 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.
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
