Hi.
I've got problem with Piano Academy app on android:
https://www.pianoacademy.app/Always when I try to connecting piano-android tablet (USB), Piano Academy app is freezing !
I try to different cables USB, andriod devices and MIDI options in DGX-670 - no luck.
Flow Key and Simply Piano apps works well.
On Roland FP10 and Casio CDP-S100 Piano Academy app works well.
Can someon confirm that Piano Academy app works well on his DGX-670?
