I started making a song from an idea a little bit ago and it turned out pretty well. Unfortunately, now that I want to add to it i'm encountering this problem where every midi note on the piano roll (and during the playback) of my lead instrument is 1 semitone above what it should be (ie. C5 sounds like D5). Is this a setting or something? There is no automation on the affected track and it's kind of driving me insane. It only happens after my first verse in the timeline, pls help!
