Do u guys actually use timstretching.

I was reading the manual and it says that it might not always be accurate. Do you guys timestretch on your computer them transfer them to the mpc or what?

I'll use it, but only keep the results if i'm happy with it. Certain samples seems to stretch better than others, so experiment with it and see how you like it.

yeah, but i dont use it to fit a beat, just to make f'd up sounds. if i wanna stretch something to get it in a loop i tend to chop it up. you can always resample it after you chopped if you want one sample for control and editing.

I haven't used the timestretch feature on the MPC 2500 yet but if your not getting the results you want from that try the warping in Ableton Live.

I use it all the time. Like episode said certain samples stretch better than others. The timestretch on the 2500 works pretty good for drum loops, the other day I took a drum loop from like 128bpm down to 90bpm and it didn't sound that bad.. it was still usable. However when stretching melodies the mpc usually will only allow for a decent stretch of about 15-20% anything more then that and you'll hear serious artifacting in the sample so for this reason I don't use the mpc to stretch melodies I use a program on the PC that does an excellent job and will stretch 30-40% without any real signs of artifacting.

To hear the effects of a 20% timestretch set your original tempo to 100bpm and the new tempo to 120bpm this is a 20% timestretch...using this method the actual tempo of your sample does not matter you just want to increase the sample by 20%.

This formula goes hand in hand with the deepsound sample calcualtors at found at this link. Awesome site check it out.

yeah, this helps if you have a good sample, and its not at a good hip hop (etc...) tempo. Just stretch it or shrink it, and then chop it up.... or you can just use the loop.

The other thing I will do is take maybe a single note sample (from chopping something) and stretch it out. This helps in using the sample to fill in long gapps, things like that. Definitely play around with it!!!

Thanks for the deepsound link Upright. Greatly appreciated.

I don't want to use it to chop long sample like for instance if i want to chop a sample into 16 pieces and timestretch each piece it should work good for that right? I mean i can timestretch each beat in a 4 bar loop in soundforge perfectly. I'm guessing the 2500 should work well for timestretching small pieces right?

Yeah I guess so....you just have to try it out.

We'll i'm guessing timestretching on the 2500 will work good for small pieces of music such as if i chop a sample into 8 pieces and timestrecthing those 8 pieces i don't plan on using to do any dramatic timestretching.

Should work fine for that.

okay thanx!

One more thing. Can you figure out the bpm of a sample by entering the amount of beats like in soundforge and how well does it work. Cuz fom reading some of the manual it says that some things aren't completely accurate.
