TimeStretch Loops

Hi there. I have a question about time stretching loops on the MPC. I think that this maybe a generic music-theory-type question rather than a MPC question, but any info would be great.

I have a load of 4 beat loops, some at 140bpm and some at 130bpm. I want to load the pads up with these samples.

The way I see it;
I can make all the loops either 140bpm or 130bpm using Wavelab and then transfer across to the MPC via USB.
or
I can time stretch the loops within the MPC, by editing each individual sample.

Can you do multiple fiile time stretch in the MPC?
Are there benefits from using the MPC (format-wise?) over Wavelab as Wavelab can do batch processing?
I mean - if there are better / different ways to attack this problem I would be greatfull for any other ideas. i.e. Can you mix different tempo loops without getting any glitching / un-sync'd loops?

Thanks again

no, you can not do batch time stretch

the benefit is everything is happening inside the box

you can but they will not match up right. there is no auto sync beat matching like in those software programs.


hope this answered your questions.

It seems the benefit is using Wavelab for processing. You won't lose any quality since there is no A/D conversion. Using the usb keeps the digital information intact.

I like this idea besides the usb transfer nonsense. I just wish the mpc had a warp marker option like Live, so you could visually stretch at different points in the sample. Or just real time timestretch with tap tempo. I don't know, I guess I have to experiment with this feature more, which I did yesterday.

Batch processing is a great idea for many reasons. Something like selecting multiple tracks in the mixing section even.

If you have a bunch to do and they start in the computer, personally i would go ahead and use Wavelab.

Dunno bout wavelab, but a lot of software probably has higher quality algos for stretching than the mpc, anyway.

Use the mpc's internal when you are just gettin down with the mpc and some vinyl or something and you just want to do one sample at a time.

or in the middle of your production if u need to change one loop.

dablunt, what MPC are you using?
There is a function on the XL (as well as the 2 knock off units) for just what you are trying to do.
Check the manual.
It won't batch but it will lock them up with no problem, and the sound quality won't suffer for 10 BPM's.
The function actually has a common sense name.
