Envelope Generators
Envelope Generator opcodes are part of the Modulation category of opcodes:
SFZ 1 EGs #
The 3 EG destinations in the SFZ 1 standard are: ampeg (amplitude), fileg (filter) and pitcheg (pitch).
The EG destinations are represented by (eg type) in the below list - so
ampeg_attack would be the amplitude envelope attack, pitcheg_sustain would be
the pitch envelope sustain level etc.
These are 6-points Delay-Attack-Hold-Decay-Sustain-Release.

- (eg type)_decay_oncc

Flex EGs (SFZ 2) #
Flexible EG can have as many points as needed. level and time for each point is set accordingly.
- egN_curveX
- egN_levelX
- egN_levelX_onccY
- egN_loop
- egN_points
- egN_shapeX
- egN_sustain
- egN_timeX
- egN_timeX_onccY
Flex EGs destinations #
These destinations are added as a suffix to ‘egN_’ - for example, eg01_pitch=2400 would have envelope 01 modulate pitch, with an envelope depth of 2400 cents.
