Patching
Patching is the ability to assign a control (Source) to any PCM 81 parameter
(Destination). This allows you to alter the value of the parameter by manipulating
the control Source. For example, you can select the front panel ADJUST knob
as a Source and an effect's Mix parameter as a Destination. This simple patch
will allow you to dynamically alter the mix of the effect whenever you turn
ADJUST. You can create as many as 10 patches, each with as many as 8 pairs
of pivot points. You can patch multiple parameters to a single controller, or patch
multiple Sources to a single Destination.
All Sources are the same in the sense that each generates an output value in
the range of 0-127. The output value is used to increase or decrease the setting
of a Destination parameter. Sources differ in the manner in which they generate
an output. Some generate values continuously (they’re always “on”); some
generate output based on the position of a particular external MIDI controller, or
an external footpedal, or footswitch. Some Sources generate output based on
aspects of physical performance such as how loud, how fast, or how hard you
play. The PCM 81 allows you to choose from a selection of Sources as shown
for each Destination. A list of the available Sources is shown on the following
page.
Each PCM 81 effect has an identical Patch row at the end of its Edit matrix where
you can make as many as 10 patches.
