AMPLIFIER
The lter audio output goes to the voice amplier. The amplier determines
the loudness of the voice over the note duration. Its output goes to the pan
module.
Each program has a programmed volume which is aected by other
parameters: principally, the amplier envelope generator, which articulates the
desired loudness shape, and the modulation sources. Through the modulation
system, the volume can be raised or lowered by key velocity or pressure.
These sources are added to the program volume. That is, positive modulation
amounts drive the volume higher, and negative amounts drive it lower.
Note that there is a maximum program volume of 99, and modulation can drive
the volume no higher. To hear the eects of the amplier envelope generator,
velocity, or pressure on program volume, lower Program Volume, and raise
the modulation source amount.
If two programs are mixed in Double keyboard mode, all of these volume
control sources will aect the balance between the two sounds.
