PROGRAMMING BASICS
Modulation Patch
MODULATION PATCHES
Connecting a modulation source to a destination is called a patch .
Procussion lets you connect the modulation sources in almost any pos-
sible way to the modulation destinations. Each patch also has an amount
parameter which determines “how much” modulation is applied to the
destination. The modulation amount can be positive or negative and will
either add or subtract from the initial value. Modulation sources can be
simultaneously patched to any 4 of the 57 destinations for each stack.

In the example above, Velocity (or how hard a key or pad is played) is "Patched" to control the
LFO rate. Since the modulation amount is negative, the harder the note is played, the slower
the LFO rate. If the modulation amount was set to a positive value, the LFO rate would
increase, the harder the key was played.
ACCENT AND VOLUME
Accent and Volume both control loudness, but behave in a slightly
different way when they are modulated. Volume can be modulated
between zero and the maximum initial programmed level. When Accent
is modulated, it
adds to the initial level.
