The ADSR module offers the classic four-stage envelope (Attack, Decay, Sustain, Release) that is not only loopable (patch the end output into gate input) but also accepts CV control over each of the stages! For the time values (A, D, R) the value set by the knob can be increased to five times the duration by the corresponding CV value. For the Sustain value the knob and CV value are simply added.
Module power consumption: 10 mA
- GATE - gate or trigger for envelope
- A CV - accept CV for attack stage of envelope
- D CV - accept CV for decay stage of envelope
- S CV - accept CV for sustain stage of envelope (value from knob will be added!)
- R CV - accept CV for release stage of envelope
- OUT - CV from envelope
- END - a trigger CV for when the envelope has finished
- MULT - unbuffered multiple, unconnected from the module's circuitry
- B. GATE - Gate signal from MIDI
- ATTACK Knob - change the attack time from 0 (percussive) to either 2 or 16 seconds depending on FAST/SLOW switch
- DECAY Knob - change the decay time from 0 to either 3 or 24 seconds depending on FAST/SLOW switch
- SUSTAIN Knob - change the decay time from 0 to either 3 or 24 seconds depending on FAST/SLOW switch
- RELEASE Knob - change the decay time from 0 to either 3 or 24 seconds depending on FAST/SLOW switch
- GT/TR Switch - switch between GATE or TRIGGER mode. When in GT mode the envelope will rise according to ATTACK knob or A CV value for as long as signal on GATE is high and once signal drops then decay part will be initiated. When in TR mode the attack part of the envelope will play out until it reaches full level and then initiate release part.
- MAN TRIG Button - sends a trigger signal to start the envelope. Always acts like a trigger even when GT mode is active. (note: the current image above does not show the trigger button)
Envelopes are one of the basic modulation sources in subtractive synthesis. They are usually used to modulate amplitude, pitch or a filter.
