I have just purchased a usb mini keyboard for use as an immediate vicinity page turner et. al. as I am an organist and I need something lower than a music stand for page turns when I cannot lift my hand to the screen. The pedal pads are too awkward for use above my pedalboard. It is a small programmable 8 key pad hard wired to usb port on NUC computer.
I assume that I need to have Power Music “discover” the device - I haven’t seen anything obvious to pair the devices.
