Time Stretch and Pitch-Shift are just horrible.

I have a great piano sample that says its 163.3BPM which first of all seems a little too much and I want to scale it down to 90BPM. So I do so and it just destroys my sample completely beyond musical use. I don't know whether I should just upgrade to OS2 with Non-Destructible Chopping? Also the pitch shift makes the samples just sound hard and now what I want them to. Is there a better solution?

I am using JJOS1, btw.

No software or hardware will sound good taking a sample from 163bpm down to 90. NDC may be a much better solution.

Thats what I thought.

BPM is kind of relative, your piano loop could also be thought of 82.5 bpm
So to get it to loop at 90 bpm you just need to tone it up a couple of semi-tones, in theory. Without hearing the sample it's hard to say for sure

That's been a long time general rule of thumb.

One hit drum shots and other quick hit type samples can take more stretch abuse and still sound good though.

Would JJOS2 be better for more timestretching and what not since it has NDC?

Timestretching on any MPC is ropey if you're too demanding on it. And yes, non-destructive chop on OS2/XL is really nice.

Why don't you download the demo and check it out?

more or less what i thought.. why not turn it up to 180bpm?

Who told you that? Don't answer that. They are 2 totally different things mind you.

NDC is where you make a virtual copy of your sample, that's all. You can VIRTUALLY chop, edit, slice whatever.
Your PHYSICAL data remains the same and isn't fuxed with at all. And since it's a virtual/logical copy of the original
no extra memory/ram space is used, it's literally going to be using like 5-7kb of mem/ram space for that virtual copy. NDC is a parameter/settings copy, not physical data copy.

Timestretch can be performed on the virtual copy and the physical sample is never touched, same as you've tried already, and you'll get the same results, lol.

Physical data copy is what mpc's on standard os's do. When you timstretch or anything else you are altering the physical data and it wastes mem/ram space cause you actually HAVE to copy the sample and that doubles the space it uses, that sucks.

I've always wondered why non destructive chops are on the ASR10 implemented WAY back in the days but not on modern hardware samplers like the mpc. But it is what it is and if you need it then get the jjos that offers that feature.

More than my standard 25-30 words but it couldn't be explained in detail any other way.

Understand more the technical aspects of things ur interested in and you can use that knowledge to further your productions. Sometimes combining features to create stuff that isn't a feature/option in your menus.

Great knowledge Lamp! Thanks. I might send you the sample I'm trying to work with in which case you could drop some more knowledge on how to help me out.

You may be pushing it now... He's already gone over the "standard 25-30 words"!

tImestretching on the mpc's suxs donkey balls. I use Melodyne plugin for that and still...

Software was the answer for me. I never stretch in the mpc. Any stretching i do is done in Reaper 3. Simply drag the sample to match the bpm in the sequencer.
