Hey... Wait a second! I don't do Ipads!??
No android version?
Well..
Since all serious music software and tools are IOS these days and not android, you might want to consider a change...(talking mobile os and not windows/mac)
And offcourse there are several reasons for this..
-due to support for musical standards in the kernel of ios (and not android) its much easier to create musical instruments for ios
-next to that when programming for android, the programmers need to adapt for many many more types of hardware, the apple development kit takes care of that on ios..
-for commercial and payed apps, software piracy on android chases off developers, and google doesn’t care about it
-android didnt add any noticable changes for tablets over the years, making android more and more a mobile phone platform that treats a tabblet as a big phone..
