resonance. 
 
ENV AMNT 3: Sets the depth of the applied envelope to the chosen destination. (See

Displays Envelopes 1 - 4, their destinations and velocity sensitivity settings. 
 
Functions that Envelopes 3 and 4 can be applied to: 
 
PW1 
(OSC 1 pulse width)
MIX3
(level of OSC 3)
PW2 (OSC 2 pulse width)
SWP3
(frequency of OSC 3)
PW3 (OSC 3 pulse width)
RMOD
(ring mod level)
MIX2 (level of OSC 2)
NOIS
(noise level)
SWP2 (frequency of OSC 2)
RESO
(resonance)
 
DYN%: (1 - 4) Percentage of velocity information sent to each envelope amount. 
 
* When using Envelopes 3 and 4 for Noise, Mix 2, or Mix 3, turn down output level in 
Audio Mix page for maximum effect. Note: Only one envelope at a time can be
