The improvisation can be audio or Midi. The point is that the improvisation is not played to a click track. The reference track contains one, and only one note per downbeat from the very beginning of the piece to the very end.

The idea is that you freely record some midi music on one track, then go back and record a reference track on some other track. Then apply the fit to improv tool and the metronome should now mathch your playing more closely. hth js Laurie wrote: Has anyone used the fit to improvisation in Sonar 4? If so, could you give me a brief overview of the steps to make it work? Does the music you play along with creating the reference track have to be midi
