Stop the bus!
@Sispence805 is talking about the BlueTurn not the BlueBoard. BlueTurn does not support bluetooth MIDI. BlueBoard does.
BlueTurn needs to be added as a bluetooth keyboard in iPad Settings. Then it needs to be added as an Airturn Keyboard, not a MIDI device. Then the actions need to be configured within the Airturn Keyboard settings, which is accessed by tapping the (i) button at the right of the added Airturn Keyboard. Once you've entered the setup page, hit the buttons on the pedal and it should light up some of the six available assignments. Some functions like changing tempo can be set up but won't work when you're playing your songs. You get around this by buying a MIDI device such as the BlueBoard or an Airturn pedal. Start and stop of playback work perfectly--I just tested it--using the BlueTurn.
You do not assign functions where you expect them to be, which is within the Assign Actions menu. This is for MIDI pedals.
Regarding the BlueBoard, this also works correctly as long as you follow some basic setup rules:
- Do not use the iRig app. Delete it!
- Hold B down when powering up the BlueBoard.
- Don't concern youself with trying to find the device in iPad's Bluetooth settings.
- Add the device in ST3's Bluetooth MIDI Devices setup.
- Configure actions in the Assign Actions page. It should respond to all four buttons.
- Every time you load up ST3, you need to manually reconnect the device in Bluetooth MIDI Devices setup. ( @peter is this normal for Airturn pedals? )
Hope this helps. Don't skip a step. Hopefully I haven't.
