Selecting A Midi Channel; Accessing Programs And Registers - Lexicon PCM 81 - REV 2 User Manual

MIDI Operation

SELECTING A MIDI CHANNEL

All PCM 81 parameters, programs and registers can be accessed by
MIDI. All MIDI applications require the PCM 81 to be connected
with one or more MIDI devices with standard MIDI cables via the
rear panel MIDI jacks.
MIDI controls, such as Transmit and Receive Channel selection are
available in Control mode Row 3 MIDI. All of these controls are
described in Chapter 2. Several are repeated here for your
convenience.
Before using the PCM 81 with other MIDI devices, all devices must
be set to the same MIDI channel. To set the PCM 81 to receive MIDI:
1. Set the controller you will be using (keyboard, sequencer, other
PCM 81, etc.) to transmit on any MIDI channel (1-16).
2. On the PCM 81, press Control. Use Select and Up and Down
to locate matrix position 3.1 Receive.
3. Turn ADJUST to select OFF, 1-16, or OMNI for receipt of MIDI
messages.

ACCESSING PROGRAMS AND REGISTERS

Some extremely useful effects can be created by controlling PCM
81 parameters remotely in real time. Almost all of the controllers
found on a MIDI keyboard or MIDI foot controller (pitch benders,
mod wheels, sliders, switches, breath controllers, foot pedals and
footswitches) can be used to adjust PCM 81 parameters. We refer
to this real time remote control capability as Dynamic MIDI®.
Sending a MIDI Program Change message (0-49) from the con-
troller will load the corresponding PCM 81 register. If any MIDI
sources are active as global or general purpose patches, moving
the appropriate control on the controller will cause the patched
destination parameter to change. (See Patching.) If you want to
use Dynamic MIDI, but don't want the PCM 81 to load new regis-
ters when you change programs on your controller, set your con-
troller so that it doesn't transmit Program Change messages, or set
PCM 81 MIDI Program Change to Off at Control mode matrix loca-
tion 3.3.
