Just picked up Ableton 8 and am using it for my dance radio show mixes. Can’t figure out how to warp a song that has multiple tempo changes in it. An example would be a song starting at 128bpm for the first few bars for mix in, then slowly changing to the songs original 80bpm and then back up to 128bpm at the end for the mix out. I’ve heard of breaking it up into separate tracks, but am not sure. Any thoughts or techniques for this?
Its a simple as leaving 2 gaps in the audio file with no warp markers in those sections to let the track shift up and down in speed in two sections (in regards of the track you talking of), the more tempo variations in a track, the more gaps you leave. This is an advanced warping technique and is more for the journeyman warper than the novice. It’s a mater of gauging when the tempo starts to drift from a regular tempo to when it settles at the lower speed then find a even increment (Warping audio is all about Even Multiplication and Division). When the track hits a contant beat, warp as normal then when it drifts leave it, move forward and play the file un-time-stretched to a further stable tempo but even period. A perfect track to illustrate this would be
The only problem with that is, you’ll need to manually change Lives master tempo during the un-warped sections.
There’s an easier way. Split the track into 3 clips:
Initial BPM 85 ----------------(Warped at initial BPM - Clip named “”)
Transition portion of track
Final BPM 120 ----------------(Warped at final BPM - Clip named “120 ”)
Set up follow actions to play the 3 tracks sequentially, and Roberts your mothers brother.
Clip 1) will play at Lives master tempo, then when the follow action kicks in, the transition portion of the Transition Track Clip 2) will play, then when the follow action kicks in, Clip 3) will play at 120BPM.
Sorry Patch I just seen my error, kind of tired been producing all night, how could it be un-time-stretched audio there are warp markers connecting the whole track, just not extra ones to even out the speed of the whole track to one tempo, will edit it.
Ok if that Patch from ALDJ, please clear up the bit I quoted on naming conventions for launching clips, I only ever did it using Scenes before, if not please do anyway and thx! Kind of sleeping atm and playing catch up with some of the new features in V 7 & 8 + I forgot a fair bit int he near 4 years I was away, use it or loose it as they say.
I was never able to really grasp the multi-tempo warping in Live. Logic’s beat mapping is way easier for me to grasp than warping in Live for songs with multiple tempo changes.
If you don’t want to separate into multiple clips you could automate the tempo change using the pencil tool in the arrangement view on the master track.
