The MPX 1 will transmit SysEx automation messages when the System mode
MIDI Automation parameter is set to On. Virtually all changes made by front
panel operations are transmitted as MPX 1 SysEx messages. This is intended
primarily for use by editor programs and in configurations where it is desirable
for one or more MPX 1s to be slaved to a single MPX 1 acting as a master. The
current mode (Program, Edit or System) of the slave does not follow the master,
but the actual parameter values do. (SysEx automation can also be stored on a
sequencer and replayed in real-time. As a general rule, automating more than
two or three SysEx parameter changes at once is not recommended.)
To set up the MPX 1 to receive SysEx automation messages from another
MPX 1, or from a computer editor/sequencer, the transmitting and receiving
MPX 1s should be set up as follows:
Transmitting MPX 1:
Recieving MPX 1:
The Receive Device ID of the receiving MPX 1, and the Xmit Device ID of the
transmitting MPX 1 must match. The Receive Device ID is an Option of the MIDI
SysEx Receive parameter. The Xmit Device ID is an Option of the MIDI
Automation parameter.
For applications where it is desirable to "automate" changes made to MPX 1
effects with its own controls ( the knob, Footpedal or Footswitch), we recom-
mend assigning the controllers to MIDI destinations (see Chapter 5: System
Controls MIDI Send) and recording the MPX 1 MIDI output with a MIDI
sequencer.
The MPX 1 recognizes the "Reset All Controllers" message. When received, all
patched parameters are reset to their stored values, or to the last front panel-
edited values. Patched parameters may also be reset from the MPX 1 front panel
—in System mode select Ctl Send from the MIDI menu and press Options.
(The message will be transmitted from the MPX 1 as well).
The MPX 1 recognizes incoming MIDI clock messages when the Edit mode
Tempo Source parameter is set to MIDI. Any Delay parameter set to
echoes:beat, or any LFO parameter set to cycles:beat, will be synchronized to
the tempo of the incoming MIDI clock.
MIDI Clock and Clock Commands (Start, Stop, Continue) are also available as
Dynamic MIDI patch sources. The value of MIDI Clock when used as a patch
source is a linear scaling of 0 to 127 (0 = 41 BPM and 127 = 400 BPM). The value
of Clock Commands when used as a Dynamic MIDI patch source is 1 for START
and CONTINUE and 0 for STOP.
