can be changed. The two auxiliary envelopes are assignable to any modulation

destination. (For a complete list, see “Modulation Destinations” on page 52.)

Additionally, any of the envelopes can modulate any destination using the modu-

lation paths. (See “Modulation Paths” on page 29.)

The envelopes can also be switched to a two-stage APD (attack/peak hold/decay)

type suited to percussive sounds simply by turning ad Mode on.

Envelope Generators: Pitch, Lowpass, Amp, Aux1, Aux2—Choose one of the

AD Mode: Off, On—Percussive sounds typically have a fast attack and then

decay to silence with no sustain. When ad Mode is on, only the attack and

decay portions of the envelopes are used, hence “AD.” ad Modeaffectsallve

envelopes.

AD Mode is effectively the same as setting SuStain to 0 and ReleaSe to the same

value as deCay, so the same effect can be achieved when ad Mode is off.

Delay: 0...127—Sets a delay between the time the envelope is gated on and

when the attack portion actually begins.

Attack: 0...127—Sets the attack time of the selected envelope.

Peak: 0…127—Peak is short for peak hold. Normally, the decay stage of the

envelope begins immediately after the attack stage reaches its ultimate value.

attack to decay. This can add extra punch to a Sound’s attack.

Decay: 0...127—Sets the decay time of the selected envelope.

Sustain: 0...127—Sets the sustain time of the selected envelope. In AD Mode,
