It's a great app for composing music, and I like to use it to figure out how my marching music is supposed to sound, but there's a problem with that. I tried to put the songs of my halftime show into the app, which has a mellophone, 2 trumpets, 2 trombones, 2 clarinets, a flute, bass drum, snare drum, and tenor drum, but when I got finished adding each part, I wanted to listen to the whole thing, but it got rud of some noyes and the time changes

This would be a great app except for one small thing: HOW DO I LISTEN TO THE SONGS I WROTE? Like there's an arrow and when I press it nothing happens. The song doesn't play, which means this entire app is just useless. I haven't been able to figure this out, I tried different wifi, restarting the app, everything, but I STILL CAN'T PLAY BACK MY SONGS. I'm on an android which is probably why so please fix this.

It's a really great app to get into composing music. I enjoy how easy it is to do things. There are some things I wish were better, like better voices for percussion. But that's pretty minor compared to what it does great at. The only small issue I have is when using the HQ trumpet, sometimes when they play again after a couple bars of rest. They completely ignore the written dynamic and overpower everything. It only ever happens when listening from the start of a piece and not a section.
