The Knob,
Footpedal and
Footswitch
as MIDI Controllers
6-4
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. See also MIDI Pgm Offset on the following page.
If the Knob, footpedal, or footswitch is active in the current program, you can
choose to have the MPX G2 send MIDI Controller messages whenever you
adjust it. This makes it possible to record real-time control of MPX G2 effects with
a MIDI sequencer — a simple but quite powerful way to automate effects.
To send MIDI data from a controller, first create a patch using the controller, then
set System mode MIDI Xmit to the desired MIDI Channel. (The default is
Channel 1.)
Once a transmit channel has been set, go to System mode MIDI Ctl Send to
assign MIDI Controllers. The display will show MPX G2 controllers and param-
eters in one field, and MIDI controller output selections in another field. (The
default assignments are None.)
MIDI Ctl Send
< > Pedal = CC7
Select the MPX G2 control you want to
transmit as a MIDI controller.
The MIDI Controller messages transmitted by MPX G2 controllers can be
recorded in any MIDI sequencer. Once recorded, they can be played back to
control the MPX G2 (and other MIDI devices) in real time. To control the MPX
G2 from recorded controller messages, reassign the patch sources to the
controller value that was assigned to Ctl Send in the System MIDI menu.
The procedures for recording footpedal movements on a MIDI sequencer, then
using the sequencer to control the MPX G2, are given below as an example:
To transmit pedal moves to the sequencer:
• Create a patch that uses Pedal as a source to control the deisred parameter.
• In the System MIDI menu, select Ctl Send and assign Pedal to any controller
(for this example, use CC4.)
To automate the MPX G2 from the sequencer:
• Change the patch source from Pedal to CC4.
Select the MIDI controller
you want to transmit.
