Bob’s suggestion of RealBand is better odds than a long shot, because it supports non-integer tempos. If it’s a free-form tempo like John suggested it could be, I really don’t know what to do.

This has nothing to do with tempos or time signatures, but there’s a small point from Dan that I’m going to be picky about because it’s often misrepresented. I know he knows this: BIAB does not ‘capture’ the chords from an imported MIDI file. The MIDI standard doesn’t include chords (even the new MIDI 2.0) so there is nothing to capture. Instead, BIAB interprets what the chords are from reading the notes. It does a pretty good job of this in my experience, until you get into complex jazz chords with slash roots where even human transcribers could have arguments about the choice of chord. This omission in MIDI is one reason that transferring a song as Music XML often works better. It has the actual chord spelling (and includes text elements too). And the time signatures and tempo are clearly given throughout, assuming they were set in the original source.
