Auxiliary Envelopes
Auxiliary Envelopes
The Prophet X has two additional 5-stage envelope generators (ADSR 
plus delay). They are useful for creating modulation that varies over time 
according to the shape of the envelope. Routing an envelope to an oscil-
lator’s frequency, for example, causes the oscillator’s pitch to rise and 
fall according to the contour of the envelope. 
As with all of the Prophet X’s envelopes, there are controls for modulating 
the envelope amount using keyboard velocity. The Auxiliary Envelopes can 
be routed to any of the modulation destinations in the mod matrix. In addi-
tion, the Auxiliary Envelopes can repeat (loop) using the 
env repeat function 
in the aux envelopes display menu. This is useful for cyclical 4-stage modulation.
Actually, any of the Prophet X’s envelopes can be routed to any destination (or 
multiple destinations) using the modulation matrix. See “Modulation” on page 47 for more 
information.

Auxiliary Envelope Parameters (Front Panel) 
3/4 Buttons: Selects either Envelope 3 or Envelope 4 for editing.
Destination: Various—Selects a modulation destination for the Auxiliary 
Envelope. See “Appendix A: Modulation Sources” on page 130 for a list of 
possible destinations.
Env Amount: -127...127—Sets the amount of modulation from the 
envelope to the selected modulation destination. Higher amounts more 
dramatically affect the destination. This control is bipolar. Positive 
settings produce standard behavior. Negative settings invert the envelope.
