I recently made a custom song in which the drums are out-of-sync with the audio by about one measure (as in, the drums start a measure too late.) It looks perfectly fine when previewing it in REAPER, but it is off-beat in-game.
The drums track is the only track that has this problem. The guitar, bass, and vocals tracks are all correct.
I embedded the tempo map when exporting the MIDI, I double-checked that the BEAT track was timed correctly. I did everything I could think of that might be causing this issue but I cannot fix this problem no matter what I do. Any help would be appreciated.
I don't know if I'm allowed to share the REAPER file, since it's a RB2 song that I re-made myself, but if anyone asks for it, I'd be happy to share the file.
