i have just tried using real band to create a tempo map for the midi file but so far no luck.
i will keep trying.

for those of you coming just coming in on the discussion.-
the aim now is to create a tempo map for a midi file and then add drums to it without altering the original midi file in terms of style/chords. the midi file has not been created using acw. (basically, add drums to a midi file). i am sure someone must have tried this or done this already.

the suggestion is, as i understand it, to use the wave file in parallel with the midi file. some more coments would be helpful.
