[sdiy] midi and clock sync (fault analysis)

The file was a recording from a MFB-522 drum machine.  Googling "MFB-522 + midi problem" yeilds a number of results (but then i 
guess googling any instrument + midi problem would do similar), however, there are a number of people commenting on issues when 
syncing to the monomachine.

Im wondering, and possibly someone else may be able to comment more conclusivly -

If this were the case, what would the expected offset be?

I havent calculated, but im guessing the wav file is about 130bpm, and the offset is about 50ms.

Leaving aside the other units the user has tested with, could the length of delay in the .wav file be attributed to bad handling of 
a run command?

Thank you,
Julian
