How can I make freely recorded (without a click) midi tracks follow the tempo of my logic project?

Question

I recorded a band (midi only + 1 room mic for reference) without a click because they wanted to preserve the human feel. Unfortunately, their human feel turned out to be a litlte bit too human. Now I would like to sync up their tempowise shaky midi performance to the original tempo of the song. Is there anybody out there who knows how to do this?

Answer 1

Are you sure you want to do this?
Really?
OK. Go to the manual and study Tempo Interpreter. This will allow you to tap along in time to the music you hear (ideally the audio from the room mic) and set up a tempo map. Actuall is harder than it sounds.
OR. Go to the manual and study Beat Mapping. You can do this to the audio (your room mic) or to midi (maybe a beter idea). It involves reading the manual (sorry about that, but it's worth it) So. Beat map your project to the performance. A bit labour intensive note by note, but ultimately it works.
Either way, if successful, you now have a logic project where the tempo map is synced to the perfomance.
Now you can adjust the tempo map. Go to the tempo operations menu, and try various alternatives. The simplest would be "create constant tempo", but then the tempo would be fixed. From there though, you could quantise as suggested above. The Q-strength option, where the quantisation strength is adjustable, is a fabulous feature for retaing some sort of human-ness.
Good luck. Better you than me.
