Is it possible to controll H9 with bluethoot MIDI with Akai LPD8 Wireless midi controller?
Technically, it should be possible to do so with both AKAI's app and H9 Control open on an iOS device. However, you don't want to rely on that during live performance because you would need to keep 2 apps open and Bluetooth communication could be unstable sometimes.
I have a Bluetooth midi controller and managed it to work with H9. It was not very stable. I've never tried this one though. It could be better or worse.
