Cèis2
Description
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.
