Bipolar Attack / Decay / Release envelope
for MIDI Continuous Controllers.

TRIGGER MODES

NOTE
Notes play normally and trigger the envelope.

MW
Mod Wheel (CC1) enables the envelope.
Below 64: notes play without modulation.
At 64 or above: notes trigger the envelope.

AT
Notes are held silently until Channel
Aftertouch reaches 64.

When pressure reaches 64, held notes
sound together and trigger the envelope.

Reducing pressure starts the Release,
but notes keep sounding until key release.

The envelope returns to Base after Decay
