3. MIDI Mode
This function provides two different modes of operation for the MIDI
interface: Common Channel or Dual channel.
Common Channel
Press the PAGE Up button to pass to the Common channel page:
3 MIDI MODE
COMMON CHANNEL
The Common Channel mode is selected by default.
With this setting the RP150 receives and sends Midi data on a single
channel only (set on the previous page), regardless of the current
keyboard mode of the Preset (single, split, layer). The Common Mode
is best used when you connect the RP150 to an expander. In this case,
changing the Presets will send Program Change messages from 1 to 64
to the expander, while changing the User Presets will send Program
Change messages from 65 to 127, allowing you, therefore, to change the
sounds of the external generator from the RP150.
A Program Change message received by RP150 on the Common Chan-
nel will not change one of the individual sound programs of a Preset.
Instead, it will be interpreted as a Preset Change message.
Dual Channel
This mode determines the MIDI channel of the main and secondary
sections of a Preset (Layer or Split).
Pressing the DATA + or – button selects the second MIDI Mode function:
Dual Channel.
3 MIDI MODE
DUAL CHANNEL
Selecting Dual Channel mode automatically disables Common channel
mode.
The MIDI channel of the main section is selected from the Midi Channel
page, as already explained. The MIDI Channel of the secondary section
(Layer or Split) is automatically assigned according to formula “N + 1”
where N = the MIDI channel of the main section. For example, if you have
assigned MIDI channel 1 to the main sound, the Layer or Split will have
MIDI channel 2. This channel will be both the send and receive channel
for the second section.
In Dual channel mode, the MIDI messages transmitted and received will
be separate for each section. The Program Change and Control Change
messages will depend on the Sound Program of the selected Preset (refer
to the MIDI Implementation chart in the Appendix).
The last MIDI Mode selected is memorized even after turning the instru-
ment off.
