Using parameter changes to control parameters

On the M7CL, you can use a type of system exclusive messages called “parameter changes” to
control specific events (fader/encoder operations, [ON] key on/off operations, etc.) as an alterna-
tive to using control changes or NRPN messages.
For details on the parameter changes that can be transmitted and received, refer to “MIDI data
format” in the appendix.
1
Connect the M7CL to your external device.
2
In the function access area, press the
SETUP button to access the SETUP screen.
3
In the center of the screen, press the MIDI
button to access the MIDI popup window.
4
Press the MIDI SETUP tab to access the
MIDI SETUP page, and select the port and
MIDI channel on which parameter changes
will be transmitted and received, as
described in “Basic MIDI settings” (
→
p. 198).
5
Use the Tx button and Rx button of the
PARAMETER CHANGE field to turn on
parameter change transmission/reception.
In this state when you operate specific parameters on
the M7CL, the corresponding parameter change mes-
sages will be transmitted. If valid parameter change
messages are transmitted from an external device, the
parameters assigned to those parameter changes will
be controlled.
Using parameter changes to control parameters
• Parameter changes include a “device number” that specifies
the transmitting or receiving device. The transmit (Tx) channel
and receive (Rx) channel specified in the MIDI SETUP page
are used as the device number.
• Please be aware that if the device number included in the
transmitted parameter change does not match the device
number of the receiving M7CL console, the message will be
ignored.
• If parameter change and control change transmission/recep-
tion are turned on at the same time, a large amount of data
will flood the MIDI port and cause overflows or other prob-
lems, so you should avoid this.
