Number Format Notation
Numbers ending with "h" are in hexadecimal format, while numbers
ending with "b" are binary format.
Characters "A" through "F" in hexadecimal numbers represent decimal
values 10 through 15. Other lower-case characters (usually "n" or "x")
can represent any number.

4.1 Program Change (Cnh)
Receive
When the "Program Change Rx Switch" is on, Program Change
messages are received on the MIDI channel specified by the "MIDI
Rx Channel" parameter.
If the "Program Change Omni Switch" is also on, however, Pro-
gram Change messages will be received on all MIDI channels re-
gardless of the "MIDI Rx Channel" setting.
When a Program Change message is received, the scene assigned to
the received program number in the "MIDI Program Change Ta-
ble" is recalled.
The effective Bank Select, Program Change range is as follows:
Bank Select MSB: 0
Bank Select LSB: 0-7
Program Change No.: 0-127
Transmit
When the "Program Change Tx Switch" is on and a scene is
switched from DME Designer, the corresponding Program Change
number will be transmitted as specified by the "MIDI Program
Change Table" and "MIDI Tx Channel" settings.
Transmission does not occur when a scene with a different config-
uration is selected.
If multiple Program Change numbers are assigned to a single scene,
the Bank Select MSB/LSB and Program Change number corre-
sponding to the lowest number will be transmitted.

4.3 Control Change (Bnh)
Receive
When the "Control Change Rx Switch" is on, Control Change
messages are received on the MIDI channel specified by the "MIDI
Rx Channel" parameter.
If the "Control Change Omni Switch" is also on, however, Control
Change messages will be received on all MIDI channels regardless
of the "MIDI Rx Channel" setting.
Control Change parameter resolution is 128 regardless of the effec-
tive range of the parameter.
For finer settings use Parameter Change.
Transmit
When the "Control Change Tx Switch" is on and a parameter is ed-
ited via DME Designer, appropriate Control Change data will be
transmitted as specified by the "MIDI Control Change Table" and
"MIDI Tx Channel" settings.
Refer to "Supplementary Information 1" for cases in which multi-
ple messages are assigned to a single parameter.
