Using control changes to control parameters

You can use MIDI Control Change messages to control specified events (fader/knob
operations, [ON] key on/off operations etc.) on the QL series console. 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.
NOTE
For details on the events assigned to NRPN messages, refer to the QL Data List (End of Manual).
STEP
1. Connect the QL series console to an external device.
2. As described in "Basic MIDI
channels that will be used to transmit/receive control changes.
3. Press the CONTROL CHANGE tab in the MIDI/GPI screen.
4. Switch Control Change transmission/reception on or off, select transmission/
