2: CUTOFF SCALING
[VOICE] [EDIT] [MENU] 3:Filter [ENTER/YES] [ENTER/YES]
[MENU] 2:Cutoff Scaling [ENTER/YES]
Cutoff scaling produces natural timbre variations across the range of the keyboard
by allowing different filter cutoff frequency “offset” values to be applied to each of
four “breakpoints” set at appropriate keys.
POINT 1 … 4
Range: C-2 ... G8
Controls: [CS1] [CS4], [-1] [+1], Dial, [SHIFT] + Keyboard
Allows four separate cutoff envelope generator level-scaling breakpoints to
be set at any notes between C-2 and G8 for the selected filter.
To use the keyboard for breakpoint entry, simply select a breakpoint param-
eter by pressing the coresponding function key or moving the corresponding
continuous slider, then press the key at which you want to set the breakpoint
while holding the [SHIFT] key.
No breakpoint can be set to a key lower than the breakpoint to its left.
OFFSET 1 … 4
Range: -127 ... +127
Controls: [CS5] [CS8], [-1] [+1], Dial
Sets the amount of level offset for each of the four level-scaling break-
points set by the “Point” parameter described above.
Negative values lower the cutoff frequency, and positive values increase the
cutoff frequency at the corresponding breakpoint. No matter what value is
chosen, the cutoff frequency will never exceed its minimum or maximum value.
When different offset values are applied to adjacent breakpoints, the cutoff
frequency varies smoothly between the breakpoints.
