MIDI
You can use MIDI control change messages to control specified events (fader/encoder opera-
tions, [ON] key on/off operations etc.) on the LS9. 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 62 and 63 to specify the MSB (Most Significant Byte) and LSB (Least Sig-
nificant Byte) of the parameter number, and subsequently-transmitted control change messages of control
change number 6 (or 6 and 26) to specify the value of that parameter.
The event assigned to each combination of MSB and LSB is pre-defined, and cannot be changed.

window.
In the CONTROL CHANGE popup window you can
specify how control changes will be transmitted and
received, and assign the event (fader/encoder opera-
tion, [ON] key on/off operation, etc.) assigned to each
control number. This page includes the following
items.
1 CONTROL 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
popup window.
