Controller Quirks; The Adjust Knob, Custom Controls, Foot Pedal, Foot Sw 1, And - Lexicon PCM 91 - REV 1 User Manual

MIDI Operation
SLAVING TWO OR MORE PCM 91s
Two PCM 91s can be slaved together by
connecting a cable from the MIDI OUT jack of
the master to the MIDI IN jack of the slave.
Additional PCM 91s can be slaved to the
master by connecting a cable from the MIDI
THRU port of one slave unit to the MIDI IN port
of the next unit. All of the PCM 91s must be set
to the same MIDI channel and Device ID.

CONTROLLER QUIRKS

Some synthesizers and controllers cannot send the full range of
MIDI program change messages (1-128). Others may appear to be
able to send only 32, but actually have a bank mode that does let
you send all 128 program change messages. Also, be aware that
some MIDI devices use a program numbering system that uses
0-127 instead of 1-128. If in doubt, see the manual for your
controller. For reference, in the PCM 91, Program Change 0 will
load the effect at 0.0 in the current bank. Program Change 1 will
load the effect at 0.1, etc.
THE ADJUST KNOB, CUSTOM CONTROLS, FOOT
PEDAL, FOOT SW 1, AND FOOT SW 2 AS MIDI
CONTROLLERS
You can choose to have the PCM 91 send MIDI Controller
messages whenever you turn ADJUST (the soft knob in Program
Banks or Register Banks modes), when you modify a Custom
Control, or use them to activate analog controllers connected to
the rear panel Footswitch or Foot Controller jacks. This makes it
possible to record real-time control of PCM 91 effects with a MIDI
sequencer - a simple but quite powerful way to automate effects.

Control 3.7 MIDI SysEx set to Receive On
To send MIDI data from these
controllers, first set Control mode
3.2 (Transmit) to the desired
MIDI Channel. (The default is
Channel 1.)
Once a transmit channel has
been set, go to Control mode 3.5
to assign MIDI Controllers. Press
Load/✱ to display the available
controllers: Foot Pedal, Foot Sw
1, Foot Sw 2, ADJUST, or Custom 1-4. Turn ADJUST to assign the
MIDI Controller data to be sent when the displayed controller is
activated. (The default assignment is None.).
When a PCM 91 controller is assigned to a MIDI Controller, the
PCM 91 will respond to incoming controller messages as though its
own controller were moved. In other words, if FootSw1 is assigned
to Sustain, the PCM 91 will respond to incoming Sustain messages
as though Foot Sw 1 had been activated.
