The Instruō cèis 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 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.

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 switch which forces completion of the Attack duration when triggered
• Combined trigger output which fires when there is a change in segment
• Variable envelope response shape from linear to exponential

Specifications:

8HP

Note: This is a used item, and while it is guaranteed to be fully functional it is almost sure to also contain "rack rash" on the mounting holes and have some minor scratches on the panel from use. It will include a ribbon cable, m3 screws, and a box, but not the original box.
