Hey guys, theory noob here,
I'm working on writing a song right now and can't figure out what key it's in. Looking through it, I found that the notes in it are C# D E F G A A#. I've looked through all of the keys in the FAQ sticky and this didn't match any. If you need it I can upload the GP5 file of it for reference. If it helps, I came across the main hook for the song while messing around in E Phrygian, though it's not quite the same.
D harmonic minor
