The RD-300GX can connect to an Apple iOS device via USB using the Apple Camera Connector Kit (or the Lightning to USB Camera Adapter for newer iOS models with the lightning connector). Use the following procedure to set up this connection:
- Press EDIT.
- Use the INC/DEC buttons to select "System" and press ENTER.
- Use the INC/DEC buttons to select "USB Driver" and press ENTER.
- Use the INC/DEC buttons to select either "GENERIC."
- Press WRITE, followed by ENTER to save this setting.
- Turn the RD-300GX off, then back on, to finish making the driver change.
- Connect a USB cable from the USB COMPUTER (square) connector on the back of the RD-300GX to the Apple Camera Connector Kit.
- Connect the Apple Camera Connector Kit to the iOS device.
This will allow you to use the RD-300GX with any iOS applications that can connect to a MIDI device - such as the Roland Sound Canvas for iOS application.
