Not impossible at all, just not very practical as lmms is a very large software and with not enough developers. It already compiles and runs on ARM processors though (latest Ubuntu development version has lmms-1.2.1 for arm64 and armhf) so you would need to decide upon a touch screen friendly interface. Lots of work. A smaller
app that could export mmp/mmpz format would be cool. It doesn't have to be based on lmms. We have the goal to implement saving sound files with the project files. You could then make a small sample player that you can make a first draft on and then load it up on your main machine. I'm not experienced enough with mobile devices though and how other people use them.
@benbou92 Can you recommend any open source music applications for mobile devices to check out?
