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.
