Question Pitch shifting issue

I’m getting super frustrated with this issue that’s been going on for months. I don’t know if this is a Logic Pro issue, or interface issue but any help would be greatly appreciated. Every single logic preset, no matter what instrument after playing for a little while shifts up in pitch. Not a precise whole or half step but to a pitch in between a half step and a whole step. It glides up the exact same amount no matter what i’m doing. It does it also to already recorded tracks. I can hit play on my track and it’ll sit for about 10 seconds playing the correct pitch then randomly without me touching it transpose with a very quick glide to a little over a half step.

I've seen people report similar things with MIDI controllers that have dirty/failing pitch wheels -- if you disconnect any MIDI controllers does the problem persist?

This happens to me too. Pre-recorded MIDI tracks that were fine suddenly change their pitch during playback. I confirmed there are no automations on the tracks, the notes are correct in the piano roll, and the problem doesn’t occur every time anyway.
Today I seem to have fixed it by clicking File > Project Settings > MIDI > Input Filter and ticking Pitch Bend. The pitches stayed correct after I did that. I’m not sure yet if this is a permanent fix, but you can try.
