VC ADSR 121 V1d 2
Features
•Controls for Attack, Decay and Release envelope phases along with the Sustain level
•Controls for the Attack, Decay and Release response shapes from exponential,
through linear to logarithmic.
•Time range selection switch x1 / x10
•Gate input for full ADSR output
•Manual gate button
•LED indicator of gate pulse integrated into the manual gate button
•Trig input for full AR envelope from a trigger pulse
•The Trig input can also be used for re-triggering the attack / decay phases whilst the
gate input is active
•CV inputs for each of the Attack, Decay and Release times
•A common CV input that sets simultaneously the Attack, Decay and Release times
•CV input for the Sustain level
