cèis

Instruō's first fully analogue voltage-controlled ADSR envelope generator in 8 HP, since replaced by the cèis[2]: attack, decay, sustain and release on LED faders, each with its CV input and a gate output held high for its stage, a combined trigger at the start of each stage, a shape knob from linear to logarithmic/exponential curves, a Gate / Trig switch and a manual button lit by the envelope.

Key features

• ADSR on four LED faders, CV over every stage
• Gate output per stage, combined trigger output
• Gate and Trig modes, manual button lit by the envelope
• SHAPE from linear to log/expo
