Envelopes

Tempest has five six-stage DAPDSR (delay/attack/peak hold/decay/sustain/release) envelope generators for each of its six voices. Two of the envelopes are “hard wired” to specific destinations: low-pass filter and amplifier (VCA). The PITCH envelope uses All Oscillators as a default destination, but it 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 modu­lation 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 five envelope generators to edit.

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 five 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. Peak briefly holds the envelope at its peak value, delaying the transition from 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, Sustain has no effects.
