Eastablishing a tempo map to a free time recording.

Free time meaning a song not recorded to a click.

I didn't think that this band could play to a click so I didn't bring it up.  But suppose I wanted to create a click after the fact or create a tempo map for purposes of audio quantization using snap to grid.

I would think if I found the snare pick up on Bar 1, beat 4 and pinned that in place with set MBT to now time and then went out a set number of bars and pinned the first note of a bar to the correct MBT using the same feature, I would get some semblance of a tempo map.  Of course, I may have to go back and pin certain spots because of tempo fluctuations.

I didn't find that this worked as well as I expected.  Any better ways to do this?

    Does Audiosnap extract tempo?

    Supposed to but it's broken in X1.  In this particular situation, I don't know how helpful that would be.

    Dave,

    I thought I saw a couple of vids on YouTube where they extracted tempo with Audio Snap?

    Dave the way you went about it would normally work pretty well, except that X1 has the same issue that 8.5.3 did that tempo changes don't get inserted where they should. It's not a big problem if you only set two points to establish an average tempo for something that was recorded to a click, and you just don't know the tempo, but when you start snapping additional points in between to follow a fluctuating tempo, things can get ugly.
     
    I would say you'll either have to go back to 8.5.3 , and use Set Project from Clip, or wait for X1b, which may fix both functions.

    I've got time to wait.  This project probably has too much bleed in the tracks to make slicing and dicing practical but it would be useful to hone the technique.

    Dave,

    A friend of mine said he successfully used a trick to get a "bleeded" track to expose better transients.  What he did was bounce the track using a gate that controlled the bleed as much as possible.  Then he used this bounced track to extract the timing.

    It's an interesting approach that might be of use in your situation.

    Use 8.5.3 - I use Audiosnap all the time for this purpose, (only thing I really use Audiosnap for...). Can be a complete P.I.T.A. inserting every measure into a project, but for synching up other orchestration to a "live" feel, nothing beats it, (except robot musicians but they scare me).

    Hi Dave-
     
    There's always the old 'Fit Improvisation" command.  Time consuming, (if you want to get it accurate) but it works.

    you could in theory use your snare as the transient shaper,then assign the snare to a click drum,like session drummer3..its like drum replacement..make a copy of your snare track and turn on transients..assign that..only problem with this theory is when your snare is not showing up as hits..you have no clicks..so youd have to add those manualy by promoting a few here and there...this help?

    Failing that, tap out your own Transient reference track using a short, percussive sound in whatever synth you want.

    Get it as close to the recorded music as possible, set all velocitites to 100 and use that to get A/S to create a tempo map.

    I've used the Fit to Improvisation to sync a midi track to a CD recording.  It worked for me but it was a bit of a time consuming chore.  But sometimes, that's what you have to do.

    I think you'll find it less time consuming when you're just taking a recording and creating a tempo map.  I think syncing up a MIDI file would be a lot more work!

    +1 to this.

    And just two weeks ago I successfully used X1a to conform a project's tempo map to a free time recording.  So, backup your project file and give it a shot. It didn't take me very much time at all.

    Some tips: bounce down a single click track or create your own as mentioned above. Make sure the clip starts right on the downbeat with no pickups. Enable audiosnap and "edit tempo map" on that clip. Make sure it's got the correct tempo and that all the markers and counters are lining up where they should be. Then set project from clip. Hopefully it'll work for you.

    That's interesting. I never tried Set Project from Clip in X1, but among the list of X1b fixes is:
     
  • AudioSnap Set Project Tempo from Clip is now functioning.  
     
    That's why I wrote Dave was going to have to go back to 8.5.3, or wait for X1b.
