The synth contains two ADSR envelopes or more specifically Attack, Decay, Sustain, Release envelopes. These two ADSR envelopes are hardwired to the two oscillators. They can also be used to modulate parameters. This has its uses for more specific effects, where a repetitive LFO modulator will repeat the cycle, the ADSR envelope will run through its stages and once the release stage is complete the value of the linked parameter will be fixed for that key press.
The interface is an interactive envelope, with the attack, decay and release points are interactive and highlighted. The controls can be displayed by using the show more controls icon on the top right.
The attack, decay and release values are in milliseconds. The sustain value is between 0 and 1.0. The hardwired ADSR's 1.0 max sustain is equal to the amplitude of the oscillator.
