instruō specialist synthesizers cèis[2]: envelope adsr price : $209.00

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.

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 modes which can force completion of the attack duration when triggered
hold mode for sustain segment lock for cv slew use
combined trigger output which fires when there is a change in segment
variable envelope response shape from linear to exponential

specifications:
8hp
depth: 27mm
+12v: 70ma, -12v: 40ma
