33 Tempest Operation Manual Envelopes
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 P
itCh
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 71.)
Additionally, any of the envelopes can modulate any destination using the modu-
lation paths. (See “Modulation Paths” on page 37.)
The envelopes can also be switched to a two-stage APD (attack/peak hold/decay)
type suited to percussive sounds simply by turning ad M
ode
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 M
ode
is on, only the attack and
decay portions of the envelopes are used, hence “AD.” ad M
ode
affects all five
envelopes.
AD Mode is effectively the same as setting S
uStain
to 0 and R
eleaSe
to the same
value as d
eCay
, so the same effect can be achieved when ad M
ode
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.
