how to sync a midi file with an audio file

I want to take a classical music piece in .mp3 (or other audio file if necessary) file and take the same music piece in *.midi file. then - I want to synchronize between them so as a result only the midi file would change and the timing of its beat would be synchronized with the .mp3. So lets say - if I would play them both on the same time they would play the same notes synchronizly.

How can I do so? (I have cubase if the answer might be there...)

It's a tough task because general beat-tracking (follow tempo changes) hasn't yet been figured out.

There's at least one tool that does work though for matching an audio file to a midi file, assuming the audio file is almost identical to the midi file in terms of the score. But I can't remember it's named, never have used it. The place is to ask is the Music Information Retrieval community of scientists:

For manual mathcing, you can use modern DAW's like Logic, Pro Tools, etc, to help you with this by providing reasonably nice tools to build a detailed tempo-map of the audio file, and then the MIDI file would line right up with it, but it's a tedious task. You'll likely need tempo changes more often than every measure to get a nice alignment - it will be style-dependent.

You could use tools that already exist. For example, if you know the tempo of the mp3, then you could use this page to change the tempo on the midi file.
