    I have a Note 1 and Note 8 and Alesis Q 49. It work both Notes. There is just a delay when playing keys on the Alesis Q49. I will just await if there are some updates to correct this issue.

    After looking for a MIDI capable Piano App I tried this one. Unfortunately the latency issues on Android are worse than I expected so I probably have to give up my dream of android based music production.
