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)_attack
• (eg type)_attack_oncc
• (eg type)_decay
• (eg type)_decay_oncc
• (eg type)_delay
• (eg type)_delay_oncc
• (eg type)_depth
• (eg type)_hold
• (eg type)_hold_oncc
• (eg type)_release
• (eg type)_release_oncc
• (eg type)_start
• (eg type)_start_oncc
• (eg type)_sustain
• (eg type)_sustain_oncc
• (eg type)_vel2attack
• (eg type)_vel2decay
• (eg type)_vel2delay
• (eg type)_vel2hold
• (eg type)_vel2release
• (eg type)_vel2sustain

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.
