I know I've done this before a few times, but I'm having a brain-sprain today and can't figure out the straightforward way of doing this...
 
The scenario
- I have an audio version of a song. 
- I also have a MIDI version of the same song.
- These were created on separate occasions, so they will not align as-is
- So far neither has any tempo map in Sonar.
 
The goal
- create a tempo map to the Audio file (easy-peasy for me)
- align the MIDI file to that tempo (which is where I am stuck).
 
How do I set MBT for the MIDI file without affecting the tempo map I generate from the audio track?  I've done this before a few times but it's been a while (Sonar 8 and prior). 
 
 
My current solution
This is the approach I am contemplating right now...maybe this is the only way?
- create a project file for the MIDI track
  - generate a tempo map for that MIDI track
  - clear out all the tempo changes so that the MIDI track adjusts accordingly
- import the audio file into the above MIDI project
  - create a new tempo map as per the audio
  - the MIDI track should automagically adjust to this new tempo map
- both MIDI and AUDIO are now in sync, with a perfectly matching tempo
- No audio should be harmed in this process ;-)
 
Is this the only way to do this?  Hmmm, maybe it is.  Now that I'm thinking about it, I seem to recall doing something similar before.  Anyway, I'll post it here in case anyone needs to do the same or has a better suggestion....
 
 

Bump,

im sorry peter,to be honest,i have no idea how this is done,lol.
but i believe other users do.
this deserves a closer look.

i hope this bump gets it rolling.

Best wishes my friend.

just a guess... click select the audio clip. press a for audio snap. turn on as, then click the extract groove button.  highlight the midi track and right click then select quantize to pool??

I have the same problem. I could not find out how to automatikly adjust project tempo according with audio track. Can you make me some print screens ? Thanks a lot. Jozef (Sonar 8.5.3)

Is the audio tempo steady (e.g., done to a click track) or was it just people playing to a drummer?
 
I assume the tempo and total track time is almost the same or this would be hopeless.
