Envelope
Attack Sets the attack time (Attack)
Decay Sets the decay time
Release Sets the release time
Sustain Sets the sustain level
Input Trigg Trigger signal input connection
Output Envelope output signal
Six in total, the modulation envelopes make the sonority evolve in function with time. An
envelope possesses four sequentially following temporal periods: attack, decay, sustain and
release. When the input trigger goes from an inactive to an active state, the envelope launches
its sequences “attack” followed by “decay” and remains in the “sustain” state as long as the
input trigger remains active. When it goes to an inactive state, the envelope begins the
“release” sequence. If the input trigger becomes inactive before the first 2 sequences have
finished, the envelope goes directly to the “release” phase.
The input trigger can be connected to the output trigger coming from the keyboard, the trigger
delay module, the oscillators trigger output, or from the sequencer.
The time of the different periods are controlled by the “Attack”, “Decay” and “Release” knobs.
The “Sustain” knob is to set the level of the envelope output during the sustain period.
