Bad sync on export

Hi guys,

I wondered if you could help me with my problem: for some reason my track completely loses sync on export. I'm using Maschine wired into FL Studio and the loss of sync happens with the Kick versus the rest of the drums (kick on one channel of Maschine, the rest of the drums on another). For some very strange reason it is all perfect synced within FL Studio but the resulting mp3 file after export has the kick slightly out of sync with everything else (very perceptible bad sync). I've tried different mp3 qualities, tried enable/disable delay compensation and even exported the whole maschine project into wave files and disabled maschine to see whether that would sort out the problem. It didn't.

Probably I'm doing something wrong, as a bug in the export function hardly would go unnoticed for long. Any ideas?

Cheers,
Ale
