Exchange tips and tricks for the Akai MPC4000

i know in the 2500 you can make a patched phrase...a loop that will change its tempo based on what tempo is set in the seq. Anyway that can be done on the 4000?

can someone drop some knowledge on that?

No, the 4000 does not have this feature.

uhh it's not the same as timestretchnig, but i think it does what you ask


when you slice a sample, say a 1-bar loop... when you do the slice, you can create a new program as well as a sequence.

now that sequence -can- be tempo-changed, and it will work similar to the way a recycle/rex loop would.

yea...i understand that..so, would u need to change the tempo by re-time streatching it, or is it done automatically?

Timestretching and chopping are two different things. Timestretching will actually alter the sound file to the correct length while keeping the pitch (although you lose quality the more you stretch). This cannot be done in realtime, but is sometimes required for complex loops or vocals.

If you chop up a sample (usually either evenly or by percusive sections) and then resequence the parts, you can then alter the tempo on the fly. This will keep each of the sections as they were but will play them either more crunched together or more spaced out depending on how you change the tempo. Chopping is the way to go for the most flexability with beats and should be learned if you want to mess with your samples and not simply reuse the same loops over and over.

so after you go to region and chop up 16 parts...u can change the "tempo" of the loop, play out the sample, and it'll put it in the right tempo based on the quantize?

im tyring here...

no
there is no patched phraze option

Yes that is right. Make sure you find the right tempo first and chop it up. Then you won`t need patch phrase cuz you can do it manually.

thanks for the love

To add on to the question asked about choppin in regions...where do you go to change the tempo once the sample is chopped into 16 pieces?

First you set the Tempo of the loop Before chopping (change end to Beat).
and then do your chopping and have it give you a sequence.
Then that sequence's tempo can be changed when played..

But we only get 32 regions on the 4k, unlike the 64 regions on the 2500...
would like the extra regions for longer samples myself ... :) IF that Unicorn OS shows up, maybe they will add that....

I always go by a basic formula for beatmapping samples by notes.

32 divided by 4 (quarter notes)=8 bars

32 divided by 8(eigth notes)= 4 bars

32 divided by 16 (sixteenth notes)=2 bars

verses the 1k or 25k`s

64 divided by 4 (quarter notes)= 16 bars

64 divided by 8 (eighth notes)= 8 bars

64 divided by 16 (sixteeth notes)= 4 bars

Depending on the loop either drums-16th notes, bass or beatmapping quarter to eigth notes. Though eigth tends to be the best for me for tempo changing basslines and full instruments.

The norm for using loops with varying tempos aka human drummers tends to be 4 and 8 bars. But at least for me the tempo varies can be alot especially over 8 bars or even 2bars so I rarely use a 16 bar loop. I would split it into two 8 bars and work from there.

Everyone can do it on the 4k just one has to take the extra step. I sold my baby 2500 aka 1k with the 64 regions in order to have a more software based studio.

It is all about the techniques for beatmapping chop small and use small loops, regions or measure however you want to call it.


P.S. if you are working with a sequencer based loop no need to worry about beatmapping so much just match your sequencer with the loop.

well, i found that in the sample/edit/SLICE menu you can slice and create a sequence, so you have all your slices lined up already in a programme and the midi data that replays them at whatever tempo you need. So even if the whole sample data is not on a single pad (as in PP with the 2500 and the 1000) you still have a very similar result.
However, I find that this feature on the 4000 lacks one important setting: I haven't found the way to set the sample tempo/bars before slicing, so it works well only for samples with 4/8/16 bars, but with a 3 bar sample the sequence is built as if it was 4 bars and the results are not usable. Any guesses?
