Volume Modulator Cross Fade Breakpoints
The cross fade breakpoints (A and B, C and D) allow you to scale the effect of the volume
modulator (selected with the Edit/Amp VOLUME MOD parameter) to create keyboard, velocity,
or other types of cross fades. Using the cross fade breakpoints, you can customize how the
volume modulator will affect the volume of the WaveSample accross the range (or throw) of its
output. This lets you use velocity, keyboard position, pressure or any other modulator to cross
fade between WaveSamples.
Think of the A-B FADE IN/C-D FADEOUT parameters as a trapezoid, whose shape will affect
the output of the modulator assigned to the Edit/Amp VOLUME MOD parameter. The A-B
FADE IN value sets the point along the throw of the volume modulator that the modulator’s
output value will begin to rise above zero (i.e. fade in). The A-B FADE TO value sets the point
along the throw of the volume modulator that the modulator’s output value will have risen to its
maximum output. The C-D FADE OUT value sets the point along the throw of the volume
modulator that the modulator’s output value will begin to fall from maximum (i.e. fade out). The
C-D FADE TO value sets the point along the throw of the volume modulator that the
modulator’s output value will have fallen to zero.
The default values are “A-B FADE IN=0 TO 127” and “C-D FADE OUT=127 TO 127,” imposing
the following shape on the output of the volume modulator. In this example the Mod Wheel is
the volume modulator:
A
0
127
BCD
zero output
max output
modulator throw
wheel down
wheel up
To reverse the polarity of the volume modulator, set the values as follows:
“A-B FADE IN=0 TO 0” and “C-D FADE OUT=0 TO 127.” The shape imposed on the output of
the volume modulation is as follows; again, the Mod Wheel is the volume modulator:
modulator throw
wheel down
wheel up
A
0
D
127
zero output
max output BC
Note:
Whenever you cross fade between WaveSamples, the WaveSamples must be in different layers,
since only one WaveSample can occupy a given key within a single layer.
See Section 16 — Instrument Programming Applications for information on programming keyboard
cross fades.
