Instruo Ceis [2]

MUSICAL FEATURES

Instruō cèis[2] is a fully analog, voltage-controlled ADSR envelope generator. ADSR envelopes are based on the East Coast approach to synthesis and are widely used in subtractive sound design. cèis[2] allows external control of attack, decay, sustain and release stages as well as outputting gate signals for each segment, providing maximum flexibility for this classic tool.

Improvements to this version of cèis[2] include a complete redesign of the circuitry for the segment gates, the addition of a retrigger input, and the addition of a voltage-controlled slew limiter function.

• LED button for output CV level and envelope trigger
• Fader and CV control for all ADSR segments
• Gate output for each segment
• Fader LEDs for segment stage status
• Gate/Trigger mode allows forcing completion of attack period when triggered
• Hold mode to lock sustain segment when using CV Thru
• Trigger output that is output when a segment changes
• Variable envelope response from linear to exponential
