4.2.5 – Envelopes (FILTER ENV - AMP ENV)
There are two ADSR envelopes, the Filter Envelope and the Amp Envelope. The Filter Envelope modulates the
cutoff frequency of the two filters with the modulation amount set by the Envelope Amount controls for each
filter. The Amp Envelope modulates the volume of the VCA by 100%.
The envelopes can also be used as sources to modulate other parts of the synth in the Modulation Matrix.
