Yes. The Roland GAIA-2 is USB Class Compliant, so it can exchange audio and MIDI data directly with an iPhone or iPad.
This lets you:
- Play the GAIA-2 keyboard along with songs played back on your iPhone.
- Use the GAIA-2 keyboard to trigger a sound module app on your iPhone or iPad.
Notes:
- Use Apple's Lightning to USB 3 Camera Adapter for connecting to the Lightning connector.
