MIDI Breakout Box (App Store link) is a new app that turns an iPad into a multi-touch MIDI router.
The $1.99 MIDI Breakout Box lets you:
- Route MIDI input to one or more different channels
- Transpose input up or down in pitch before sending it to the output channels
- Change instrument presets, volume and stereo panning on output channels
The latest version also adds support for keyboard splits.
Note: This App requires a MIDI hardware interface connected to the iPad via the USB Camera Connection Kit.
