Time Stretching part of sample

I'm a new MPC2500 owner (well, two weeks virgin).
Scenario:
I've a 1 bar drum loop and I want to stretch the last snare to twice its length.

How??

I highlight the snare and go to time-stretch, but it only seems to save it as a separate new sample! Overwrite replaces the original sample with a stretched version of the snare. This stretched version of the snare has loads of chopped-up stuttery bits of sample placed after the stretched snare, so I have to cut that off!! What's that all about?!

When you select part of a sample and reverse it, the original sample is left intact with the bit that you reversed... reversed. When you select part of a sample and time-stretch it, the original sample stops playin ball and clears off!!!
eh?

so, the only way I can do this at the moment would be to stick my stretched snare onto the end of a drum loop with it's snare cut off.
How the hell do you concatenate samples?? (i.e. paste a sample to the end of another sample).

why not break up the entire loop into its respective parts and then you can just stretch the last note to whatever you want? or you could create a fill using earlier notes.

I do that of course, but the point is, I want to go into one of my loops and stretch parts of it, quick and easy-like, whilst keeping it all connected.
... and how do I paste a sample onto the end of another in the MPC? i'm guessing it's not possible.

p.s. I'm using JJOS 5.03

yeah you can't do that without dropping that into an editing app

you could copy the sample 2 times and trim off the snare at the end of the first sample
then on the 2nd sample trim off all BUT the sample you want to timestretch.

then program in both samples to make em sound like 1, then tiemstretch the snare sample til the entire break loops well again

and then go into record mode and resample what you just did to get what you're looking for

just curious? why do you want to time stretch the last snare? what exactly do you mean by this? are you trying make your snare sound bigger? are you tryin to get the loop on point? let me know?

Yeah Nym... I get ya. Quite long-winded though innit!
I like the fact that you can reverse bits of your sample quickly, so it seemed an obvious follow-on that you could stretch bits of your sample... but no .

brl - I just used that 'last-snare-in-a-loop' as an example.

I'll give you another example:

Sequence 1:
On track 1: Drum beat (kicks, snares, etc).
On track 2: Pulsing fat analogue bass (16 pulses per bar).

with track 2:
I want to maybe select the second pulse, reverse it, then double its length, then go to the 5th pulse and half its length, then select from in the middle of the pulse I've just halved until the middle of the the next pulse after it, reverse and stretch that selection by 2, then take the 7th pulse and half its length, etc, etc, etc.... half it, quarter it, triple it, etc, etc, etc...

Basically, for syncopated rhythms and tempo-based, maths-based s**t. To really flip about with timings and get to the basic bare-bones of the ppq... or sumthin

All I'm saying is that it'd be nice to have that facility. I just didn't know whether or not it was possible yet.. JJ?

I wonder what that would sound like

I'm not a fan of the 2500 timestretch, which is about the only feature of the 2500 I'm disappointed with (OK, there's what seems like hurried MTC implementation, but it does at least work). I use either an S3000 (and chop in Recycle or Peak) or a combination of software (Phatmatik Pro for stretching, bounce a wav out of Logic, then chop in Recycle or Peak).

My advice (but hey, wtf do I know), if you're doing bigger timestretches (I'm generally taking 120-140bpm funk/soul breaks to 170bpm) is find an alternative to the 2500, unless one of our resident pub geniuses has figured out how to get perfect sounding timestretching on the 2500 (I'm all ears ).

I still find it hard to work out how a 2005 all-in-one sampling drum machine workstation music/midi/insert 'm' word here production centre fails to fully incorporate one of the best features of its forefathers. Did I mention they were both made by the same company? That Japanese skunk must be better than the Dutch (ie grown in a basement somewhere in Greater Manchester) rubbish I get... Not that I went to Eton or anthing.

lol

aye!

well. . . .

slightly off point:
Has anyone actually noticed that the different time-stretching algorithms sound like they're doing anything different from each other??
just extremely subtle is it?
