Seen this toutorial on you tube, where this guy edit`s a sample into Patch phrase and afterwards does a real time time stretch over the 16 levels.

http://www.youtube.com/watch?v=--GzodmsZtI

I tried the exactly same thing, but it doesnt work.
The 16 Levels just do what they always did, speeding up, or slowing down the god**** sample..

Could that have something to do with the JJ`OS ?

no.

there was no audio timestretching going on in that video, and certainly no realtime timestretching - the guy confused his terminology.

there wasn't even any realtime pitchshifting. there was no stretching involved at all--except for the detuning which he was doing with the 16 levels.

of course your audio is going to speed up/slow down. you're putting it on 16 levels.

for future reference, timestretch is located in TRIM and ONLY in TRIM. neither the 2500 or the 1000 can realtime timestretch.

Ahh...ok (?)

What was he doing then..?
i mean, i followed his instructions, with a different result..

What are you trying to say ?
I mean you see it there, right ?
+ they are also selling toutorials for the Mpc 2500..

By goldenchild Sun Aug 05, 2007 10:23 pm
Ok, let`s forget about the terms "realtime" and "time stretch" for a moment.

This "detuning" the sample without changing the tempo, obviously over the 16 Levels, how does it work ?
What does he do that i might have missed, to make this work?

Maybe the other Hand was involved, holding a button or something..

if you set it up right, assign a patch phrase to 16 levels, it will tune your sample (like 16 levels normally does) without affecting the length of the sample, it's good for basslines and drums

But thats not what im looking for and thats not what this guy has shown in the toutorial.
He is also talking bout "without changing the length" what he does, is frst off using the 16Lev without changing the tempo, wouldnt you say ?

What 16 levels normally does - it changes the tune of an sample, by making it faster and slower, when you go into the mode "tune".

what patch phrase does is split the sample into regions but still keeps the sample as a single file. when you hit a pad with a patch phrase sample it will play each region in time with the tempo. if you use 16 levels, it pitches each of the regions up, but still plays them in time with the tempo. it doesn't time stretch.

it's right there in your manual.

"without changing the length"


no. the PHRASE wasn't changing length. the individual "beeps" he was playing WERE changing length as they were being detuned.

ie: at +12 semitones:

bep.......bep........bep........bep

at 0 semitones:

beep.....beeep.....beeep.....beeep

at -12 semitones:

beeeeepbeeeeepbeeeeeepbeeeeep


note: each beep is spaced evenly
but as they're pitched down, they slow down because they're being tuned

the only reason you didn't notice that in the video is because he was using 16 levels, which is only an octave and some change - not enough for you to realize that he was not in fact timestretching.

i left a comment on this youtube explaining where he was wrong.

Ok, first off thanks to Antonym & Mike Feedback.
Now, i understand what`s goin on and why it didnt work, when i was trying to do the same.

This Guy on the Tutorial simple goes to Autochop without paying attention, where the chops been made and if the accurate.
Since he got such a simple and totally on point played sample, also with enough space in between the single notes and just 1 Instrument in it, the MPC puts the slices on the right points automatically.

When you have a sample that is full with other instruments, so where there are no Gaps for example, you have to slice it a the right points to make it work.
Cuts have to be in sync with the sample.

Then the slices which are cut to the beat, can be slowed down or made faster by tuning with the 16 Levels, but the tempo of the whole sample doesnt change and you probably will get good results as long as the single cuts do not overlap.
Right?

boom, you've got it!

you probably will get good results as long as the single cuts do not overlap. Right?


OR as long as the single cuts don't exist too far away from each other (pitched up too much). this will make them sound really choppy. again, this wouldn't have mattered in the video because the sample was very very clean (probably sampled from vst or something).

if you try to pitch up a vinyl chop you'll start hearing the thing's breaking chopping points, which can be nasty sounding.

honestly though, patched phrase is just a slightly quicker way of putting a sample into your sequence. the downfall of a patched phrase is control - you don't have much control over each individual slice.

if you instead chopped each sample to its own pad and rebuilt the original sample, you have total control over each slice - attack, decay, filter, velocity - every parameter to work with instead of just 1 for the whole patched phrase.

Well, i ef`d around with it a little and now i find it quite useful.

as far as i can see it's useful because it's easy. nothing it does cannot be done without it, and i'd prefer something else to be in it's place. course, i've got a 1k, so i shouldn't even be posting here. :lol: 8)

:)

I switched from PC with Software Sampler to the 2000xl and then to the 2500, cause i wanna make Music instead of spending/wasting hours with prepairing, before i can get creative.
So, one of the things most important to me is having a good workflow..

Let it be easy, what`s goin on in my head during the process of making music is complex enough :lol:

i'm of a different school of thought where the discipline it takes to master the technical side of things allows the creative side to flourish of it's own accord.
