You can use MIDI control change messages to control specified events (fader/encoder opera-
tions, [ON] key on/off operations etc.) on the M7CL. This capability can be used to record fader
and key operations on a MIDI sequencer or other external device, and play back this data later.
You can use control changes to control events in either of the following two ways.
●Using control changes
This method uses typical control changes (control numbers 1–31, 33–95, 102–119). You can freely assign an event to each
control number.
●Using NRPN (Non Registered Parameter Number)
This method uses a special type of control change messages called NRPN.
NRPN uses control change numbers 99 and 98 to specify the MSB (Most Significant Byte) and LSB (Least Significant
Byte) of the parameter number, and subsequently-transmitted control change messages of control change number 6 (or 6
and 38) to specify the value of that parameter.
The event assigned to each combination of MSB and LSB is pre-defined, and cannot be changed.
1Connect the M7CL to your external device.
2In the function access area, press the
SETUP button to access the SETUP screen.
3In the center of the screen, press the MIDI
button to access the MIDI popup window.
4Press the MIDI SETUP tab to access the
MIDI SETUP page, and select the port and
MIDI channel on which control changes will
be transmitted and received, as described
in “Basic MIDI settings” (→ p. 198).
5Press the CONTROL CHANGE tab to
access the CONTROL CHANGE page.
In the CONTROL CHANGE page you can specify
how control changes will be transmitted and received,
and assign the event (fader/encoder operation, [ON]
key on/off operation, etc.) assigned to each control
number. This page includes the following items.
1CONTROL CHANGE field
Here you can switch control change transmission/
reception on/off, and specify whether control changes
will be echoed out. This setting is linked with the
CONTROL CHANGE field of the MIDI SETUP page.
BCONTROL CHANGE MODE field
Here you can select the control change transmission/
reception mode. This setting is linked with the CON-
TROL CHANGE MODE field of the MIDI SETUP
page.
CList
This list shows the event (fader/encoder pattern, [ON]
key on/off operation, etc.) assigned to each control
number.
•NO..................This indicates the control number.
You can use control numbers 1–31,
33–95, and 102–119.
• CONTROL CHANGE EVENT
...........Indicates/selects the type of event
assigned to each control number.
When you press an event, the MIDI
CONTROL CHANGE popup window
will appear, allowing you to change
the control number assignment.
DCLEAR ALL button
Pressing this button will delete all event assignments
in the list.
EINITIALIZE ALL button
Pressing this button will restore all event assignments
in the list to their default state.
FScroll knob
This knob scrolls the contents of the list. You can use
multifunction encoder to control this.
