RADIAS' MIDI OUT connector to the MIDI IN connector of your external MIDI device.
MIDI channel settings – Getting ready to play
If you're using the RADIAS as a sound module or as a master keyboard, you'll need to set the RADIAS'
global MIDI channel to match the MIDI channel of the external MIDI device that you've connected.
To set the RADIAS' global MIDI channel, use the Global mode P04: MIDI page "MIDI Ch" setting.
Here's the procedure for setting the MIDI channel.
Make sure that the RADIAS is correctly connected to your external MIDI device.
Press the [GLOBAL] button.
You will enter the Global mode. The display will show the Global mode P01: GLOBAL page.
Use the 16KEYS [SELECT] button to select PAGE (the
PAGE LED will light), and then press the 16KEYS

MIDI device you've connected.
Make sure that the "Routing" setting is set to USB+MIDI or MIDI.
"Routing" speciﬁes whether MIDI data will be transmitted/received via the USB connector or the
MIDI connectors. If this is set to USB, use the cursor buttons to select "Routing" and then use the
[PROGRAM/VALUE] dial to choose USB+MIDI or MIDI.
With this setting, MIDI data will be transmitted/received via the MIDI connectors.
Press the [PROGRAM] button to return to the Program Play mode.
Set the MIDI channel of the connected external MIDI device to match the RADIAS' MIDI
For details on how to do this, refer to the owner's manual of the external device.
Any Global parameters that you edit will revert to their prior state if you turn off the power without
writing the changes into memory. If you want to keep your changes, be sure to perform the Write
operation. For details on Write, refer to p.68 "5. Saving global parameters (Write)."
A RADIAS program consists of up to four timbres, and you can specify the MIDI channel individ-
ually for each timbre. If you're playing the RADIAS from an external MIDI device, only the tim-
bre(s) set to the same channel as the global channel will produce sound.
