@thor What DAW are you using?
(The brilliant developers of DAWs have made efforts to complicate cooperation with different DAWs.)
@AmpBenzScientist I'm using Logic on macOS and he's using FL Studio on Windows. Exporting and importing some WAV files isn't the issue. But no tempo data in the MIDI file. There were only 3 tempo changes, so I wrote them out for him, but apparently, the GUI in FL Studio doesn't permit you to actually type those in. You have to screw around with automation curves, so you can't get precise changes.
