I am trying to figure out how to pitch adjust samples without affecting their length.

Example would be a short vocal piece that I want to pitch up. When I adjust it using the tune function in the program it works for that but the sample length is shortened significantly. Same if I am tuning down, it is extending it.

Is there a way to do this on a 2500 that I am missing?

Thanks.

You would have to go to the trim screen, edit, then use the pitch shift feature. But it's destructive and sounds bad imho.

Yeah I found that, no all that happy with how that is sounding. Messing around with patch phrase now and 16 levels, still not what I really want it to do. Thanks for the quick reply's

What i did for awhile, was use a realtime pitchshifting program like elastique on my computer.

I would set up a program with the sample I wanted to pitch, and send it out one of the assignable outs. Pitch shift in real-time on the computer and when happy with the result I would re-sample it into the mpc, and trim it up.

Once you have it set up it doesn't take that long, and just keep it hooked up for the next time you may need it.

Sound Forge Pro 10 will give you the best "Pitch Shift" results. Just click "Preserve duration" so your sample keeps its duration. Also, you have many presets you can choose from, depending on the results you are looking for. Very precise pitch shifting. It also has pitch bend.

Pitchshift or timestretch more than 10-15% will start to sound unnatural. Go way outta bounds and get way outta bounds results.

Soundforge has ALWAYS given me the best results.

Pitch shifting in hardware MPCs is a funny old beast. I was fine tuning a bunch of similar sounding samples the other day (+/- 3 cents), and 5 samples in it was sounding ok. I got to the 6th sample and the damn thing just wouldn't work without introducing blips and artifacts. I went through every single preset trying to flog a dead without success.

I just fired up an old copy of Soundforge in the end. :fku:
