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

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.

PDF export not working (free version). I was excited to be able to share with actual musicians the scores of the MIDI music I write, but the PDF isn't saving on my phone (moto e, fully updated). I've granted storage permission. 3/23/23 reply to developer: I see the popup with OPEN button. If I open PDF with Drive viewer, I'm kicked back to the app with no explanation. I installed Acrobat; I get an illegible error. I screenshotted the file path but when I open the location there's no such file.
