Auxiliary Envelopes
The Prophet 12 has four, five-stage envelope generators. Two of them are
dedicated to the low-pass filter and VCA, but the other two can be routed
to any of the modulation destinations.
Note: Actually, any of the envelopes can be routed to any destina-
tion—or multiple destinations—using the modulation matrix. See
Modulation on page 32 for more information.
See Low-Pass Filter on page 18 for an illustrated example of an
envelope generator.
Destination —The parameter being modulated by the envelope. See
Modulation Destinations on page 50 for a list of possible destinations.
Envelope Amount: -127...127 —Sets the amount of modulation from the
envelope to the chosen destination. The modulation amount can be posi-
tive or negative, allowing for inverted envelope control.
Velocity’Envelope Amount: 0...127 —Enables keyboard velocity to
modulate the e
nveloPe
a
moUnt
.
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 envelope.
Decay: 0...127 —Sets the decay time of the envelope.
Sustain: 0...127 —Sets the sustain level of the envelope.
Release: 0...127 —Sets the release time of the envelope.
Repeat: Off, On —When on, the Delay, Attack, and Decay segments of
the envelope repeat. Sustain still affects the level at which the Decay
segment ends, but—instead of sustaining at a fixed level while a note is
gated on—Delay, Attack, and Decay loop until the note is turned off. The
Release segment begins when the note is gated off, just as it does when
Repeat is off. For an illustrated example, see Low-Pass Filter on page
18.
