Where is Bluetooth...?!

[pdxdjazz]

Ok, thanks. I had the impression iReal Pro could play audio through Bluetooth speakers...? And I presumed my piano could act as speaker. I don't mean to control anything with it. I must have been misinformed in various ways then.

Again, it has nothing to do with the iRp app, it's the audio output of your device.
With bluetooth "ON" in both devices (iPad and speaker) check the list of "discovered devices"(Systems > Bluetooth)
Select the device you want to "pair" with your iPad. You can "pair" with only one Bluetooth device at a time.

Additional wireless external keypad or headphones or other Bluetooth speaker must show "Not Connected" in order to "pair" with a new device. (Your Kawai that you wish to use as an external speaker)
