Hi So I've got this jazz session I did in a studio a while back (on Protools) that I want to try various edits on here at home (in Logic). I've got all the required separate audio files loaded into a Logic Project and everything sounds and works fine. But this music was not recorded to a click so there is no beat/bar structure assigned to the audio. Some things were played a bit sloppy and the tempo varied a bit too much for my tastes, so I'd like to see if I can make it any "better" by doing some audio quantizing. I've got a little bit of experience using Flex Time (but since I don't really know what I'm doing I might just be getting lucky). Yesterday I thought I'd created a decent working beat map for this tune but the transients I used for it came from the right side of the drums overhead mics which then created a problem with the left oh mic's track which was locked with the above mentioned track as part of a split stereo file when I started the beat mapping process. This seemed to cause some very weird behaviour when I un-muted the other tracks but I'm not sure I understand why yet. But, assuming that I can actually create a decent Beat Map for this tune, all that will do is to make Logic's internal click follow the music's beat structure by adding Tempo Change events to the project. The question then is, how do I remove the tempo map, so that I have a single tempo from beginning to end, with the audio quantized to the Logic's beat structure? I saw no way to do this in Logic's menus or in the manual, so I went at it from a different angle. I decided to try simply using Flex Time w/o a Beat Map to move the audio so it lines up with the beats for a single steady tempo in Logic. This actually worked out OK (I think) for about 8 bars but took an awful lot of time for just the drum tracks (9 tracks of drums) and I can see that doing the entire 5 minute-long tune this way will drive me nuts. This tune's timing is quite complex and employs many time signature changes and poly-rhythms, so the whole endeavour might be doomed anyway, but if there's an easier way to any of this I might still give it another try. Any tips? Also... When using Flex Time in the past, I usually got the best sounding results with the Polyphonic Mode and that's what I was also using on the drums overhead mic's tracks. Because the overheads have a lot of wash from the cymbals I figured I'd need the time-stretching abilities of Polyphonic Mode, but would I be better off using Slicing or Rhythmic Mode on these overheads tracks instead?
