There are two options to connect the iPad and Virus TI
- use the Apple Camera adapter to connect a normal USB to MIDI Interface (I use for example this one from Roland )
- Use Bluetooth midi plugs in the virus (for example these WIDI Master plugs)
You can connect the virus USB directly to your iPad, and it will allow you to use the virus as a audio interface.
MIDI however will not work. This is a limitation of the Virus Synth. The MIDI on USB implementation is not recognized by iPads somehow, and therefore also not available in my app.
