Best way to time/tempo stretch an entire sequence

Post by Killahurts »

I have a sequence of audio tracks that were recorded at 124 BPM, and I want to do an EDM remix at 140. I want to just convert the whole thing, i.e. every track/sound bite, to the new tempo, and I want to be sure to take advantage of DP's new time-stretch improvements.

It's a remix, so of course I'll end up chopping it up, replacing the drums, etc., but I have a lot of vocal and instrument tracks to go through, and I'd rather not have to time-stretch (or in this case, compress) every individual sound bite to fit.. besides, I don't see a way to time stretch a sound bite from one tempo to another, only one time to another.

Hoping there is an easy way to do this in DP! Thanks!

Math. I'd figure the new length elapse time and set the time stretch accordingly.

You know, I always thought of a DAW as essentially a very complex math program.. it is way more capable than I am at calculating this kind of thing.. or so one would think.

Thanks for the response MLC, but.. they really left this capability out? Doesn't make sense.

Isn't there a preference that will cause the soundbites to conform to new sequence tempo...? If so, enable that preference, than change your project tempo to 140 and wait for the computer to "do the math". Of course, a "Save As" first won't be a bad idea.

Yes. Set your new tempo, then select all soundbytes and choose "Set Soundbites to Sequence Tempo".

Some things to consider:

1. If your computer is an older (like pre 2013) Mac, select just three or four soundbites at a time to
process.
2. Make sure you make the range of each selected soundbite conform to start of sequence (bar 1 beat 1 tick 1) to about two to four bars after the soundbite ends. Just to be safe.
3. If you want to adjust cymbals, synth pads, strings, or anything with a long sustain or long decay and release, I suggest recording those again at the new tempo. I'd actually do this for all drumkit pieces. Why? Because the drumkit piece's natural decay would be the same regardless of tempo.
When you time-shift a drumkit piece, its decay gets compressed or extended which doesn't sound right.
4. When happy with all time-shifted tracks, delete the old tracks to free up space and let your project run leaner.

Wow Dave, thanks!

I'm going to try this today.. I plan to recreate everything except the vocals and certain bass and guitar sounds, so I won't have any pads or drums, etc.

As a matter of fact, since (I'm assuming) I will be selecting the soundbites in the Tracks overview for this process, I can just delete the tracks I know I'm not going to use in advance.

I'll report back later!
