CUT (Cutoff Frequency)
Sets the cutoff frequency of the low-pass filter from “-64”
through “0” to “+63”. Negative values lower the cutoff
frequency, producing a “darker” sound. Positive values
raise the cutoff frequency, producing a brighter sound. The
graphic filter response curve will shift to indicate the
current setting (the heavy default setting curve will also
remain on the display).
RES (Resonance)
Adjusts the height of the filter’s resonance peak from “-
64” through “0” to “+63”. Negative values lower the
resonant peak producing a “flatter” sound. Positive values
increase the resonant peak, emphasizing components at
the filter cutoff frequency. The peak on the graphic filter
response curve will grow or shrink to indicate the current
setting (the heavy default setting curve will also remain on
the display).
DECAY (Decay Rate)
Adjusts the decay rate from “-64” through “0” to “+63”.
Negative values produce a slower decay while positive
values produce a faster decay (Unlike the Decay Time in
normal Voice Editing (page 71), this parameter sets the rate
for how much the level of the instrument decays. There-
fore, positive values produce a faster decay.). The graphic
envelope generator curve will shift to indicate the current
setting (the heavy default setting curve will also remain on
the display).
