As I'm also very interested in OMF support here are some for testing:
https://stash.reaper.fm/oldsb/121664/...rom-Nuendo.zip
exported from Nuendo, contains a one bar drumloop, if imported correctly the clips should line up in a "zig zag" manner in three stereo tracks starting at 5fps and play back seamlessly (clip fade ins/outs should be audible in the "with clip volume and fades" OMFs), Project settings: 25fps, 44,1 kHz.
The file names are self-explainatory, I think.
Hope it's useful.
