Music Studio sometimes skips events from MIDI keyboard - key press and release, pitch band etc. This problem occurs 1-5 times per minute. As a result keys “sticks” or not pressed when needed. I am a street musician, and this is very unpleasant bug for me.
This problem occurs in all my Android devices (Samsung S9, Asus Zenfone Max Pro M1, Lenovo M10 Tablet), with any MIDI keyboads, with any USB cables and adapters. Other similar applications, such FL Studio works normally.
Please help! 
Thank you for reporting this bug! We can reproduce it, somehow the MIDI driver seems to drop an event from time to time.
We’ll try to fix this in a future update, but I can’t give you a time estimation.
