Midi Timing Bug ?

[Aneng]

Hi,

Playing around with several imported midi files today, I was hearing some notes playing slightly out of time, so I rewind and play that section again - no timing problem. A bit further on in the song... same thing - notes DEFINITELY (i.e. it's not my ears !) out of sync with the rest, rewind to just before the wonky notes, and lo and behold... it plays perfectly.

Has anyone else noticed similar 'vanishing' timing problems ?

Cheers,

Aneng.
