Hey guys, quick question.

I have a tempo/time signature change in Reaper where I use "Allow partial measure" because the change happens mid-bar. It sounds perfect in my project.

But when I Export Project MIDI to get a tempo map for another studio, that partial measure info completely vanishes. The MIDI file rounds the change to the nearest full bar, making the grid go totally out of sync.

Is this a known MIDI format limitation, or is there a trick to make Reaper include partial measures in the MIDI export?

Hi everyone,

I’m preparing a session in Reaper to take to a studio that uses Logic Pro.

My song has a few time signature and tempo changes (going from 100 BPM 4/4 to 200 BPM 3/4). The transition happens in the middle of a bar, so I checked the "Allow partial measure before this change" box in the tempo marker settings in Reaper. In my project, this works perfectly and everything is synced.

However, when I try to Export Project MIDI to create a tempo map (.mid file) for the studio engineer, the "partial measure" information seems to get lost. When I test-import the MIDI file back into a fresh project, the tempo change gets rounded/snapped to the nearest full bar, which causes the entire grid after that point to become misaligned with my recorded audio guide tracks.

Has anyone encountered this limitation with MIDI file exports and "allow partial measure"?

Is there a workaround to successfully export this specific tempo map so that another DAW like Logic Pro can read the partial measure correctly, or should I just have the engineer map it manually in the studio using my printed audio click track?

Thanks for any help!
