peter Any midi interface that runs on iOS will work. You could also use a regular audio interface with midi ports. That would have the advantage of also serving as the audio output.
don7percent I am using a Donner Bluetooth controller, I had been previously using it to utilize the lyric scroll through my Apple Music before my bass player turned me on to ST3. We had it connected and working initially, now the app won’t recognize it. Got a show tonight and was trying to use it. HELP! Lol
peter I have never heard about this donner device but from pictures I gather that you can select different key commands on the device. Make sure you have not switched to another set of key codes after assigning commands in ST3 to them. Maybe reassign the commands in ST3.
don7percent It won’t even connect up to ST3, in my iPad settings it’s showing that it’s connected This is what the pedal looks like: Like I said previously it’s recognized by my iPad but doesn’t seem to connect when I try to sync it with ST3
peter Try to change the mode. I can't really see the icon for your selected mode but it might be play/stop which is not supported by ST3. You need to use something like cursor up/down or left/right. And then this device will be recognized as an Airturn Keyboard device. So you need to enable Airturn in ST3 and select a keyboard device.
