Patching - Lexicon PCM 90 - REV 1 User Manual

Patching is the ability to assign a control (Source) to any PCM 90 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.
About Sources
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 gener-
ate 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 90 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.
The Patch Row
Each PCM 90 effect has an identical Patch row in its Edit matrix where you can
make as many as 10 patches.
To make a patch, use SELECT and the Down button to move down through the
Edit matrix to the Patch row. A display such as the following will appear.
SELECT will move you across
the Patch row (0-9).
The Source type is indicated here.
(Int, MIDI or 001-119 to indicate a
MIDI Controller.)
Pressing the Load / button will change the display to allow you to sequentially
select: Src, Dst, Src Value and Dst Value. Press Up or Down together with
Load / to backstep to the previous parameter.
The asterisk ( ) indicates that Sources will be selected when
you turn ADJUST. Press Load / to change the selection to
Dst. Press Load / again to bring up the Values display where
you can select Src Value and Dst Value.
