5. Connecting the audio inputs – INPUT jacks
You can connect any audio source (synthesizer, CD player, etc.) to the INPUT jacks. Via this connection, the
audio coming from this external source can be processed in the same way as the RADIAS' internal sound
generator, or used as the carrier or modulator for the vocoder. You can also use the RADIAS as an effect
processor for an external audio source.
For details on these settings, refer to p.26 "Processing an external audio source."
6. Connecting your computer
The RADIAS provides both MIDI connectors and a USB connector.
Both can transmit and receive MIDI data in the same way. Use the type of connection that's appropriate for
your setup. You'll need to set the Global mode P04: MIDI page "Routing" appropriately for the connection
you use. (☞p.116 "Routing")
Connections via the MIDI connectors
Use MIDI cables and a MIDI interface to connect the RADIAS to your computer.
Connections via the USB connector
Use a USB cable to connect the RADIAS to your computer.
For details on the appropriate settings to make on the RADIAS so that you can use the RADIAS Sound Ed-
itor software, refer to p.71 "Using the included RADIAS Sound Editor software." For details on installing the
software, connecting and adjust the RADIAS' settings, and using the software, refer to "USB-MIDI driver
installation and settings" and the RADIAS Sound Editor software owner's manual on the CD-ROM included
with your RADIAS.
Connecting the RADIAS' dedicated keyboard RD-KB
For details on how to connect the keyboard, refer to the owner's manual included with the keyboard RD-KB.
Data transfer is faster via the USB connection, so we recommend that you use the USB connector.
If you use MIDI cables to connect the RADIAS to your computer, you'll need to purchase a sepa-
rate MIDI interface of the appropriate type for your computer. For details on connecting the MIDI
interface to your computer and how to set the MIDI ports, refer to the owner's manual for your
If you use an external MIDI sequencer or a sequencer program on the computer you've connected,
playing the RADIAS' keyboard will cause notes to be sounded in duplicate if your sequencer's
Echo Back setting is turned on. Go to the RADIAS' Global mode P04: MIDI page and turn "Local
Ctrl" off (☞p.116 "Local Control") so that the internal connection is disconnected. However, be
aware that if Local Control is off, there will be no sound if you play the RADIAS' keyboard when
using the RADIAS by itself.
