Technical questions for the MPC2000xl and the MPC2000

ok complex cats...

who knows the secret of creating a scale of notes from a single sample (not the 16 levels-disgusting sound).

I heard there's some kind of equasion done through time stretching and tuning.
i read an rjd2 interview and he breifly went into his process of transposing and so on but he also maintained he usually looks for all the different notes on the record and samples them if he can (he also has the best collection of breaks ever and i don't...suppose thats the problem).

ive tried it a bit with an organ sample and it worked ok cos its like a full bodied sound, but with piano and guitar stuff when i try the same method the new note sounds out of key.

peace to all the hard core pad tappers
so i suppose my problem isnt really the process of gettin the note, but keeping it in the right key

**** it i'll just go back to loops.

Yo:
It's a little bit of ear training; you have to at least know what note it is that you grabbed. Open it in a program like sound forge. Save it as an acid file which gives you the option of root note for transposing. \
Then you can open the sound in acid multiple times and change the key and export each sample from a - g; feed this into your sampler or sampling app and you should be able to build a full range fairly from that point on.

Peace

I usually doit by ear since it is a lot faster that pulling it up in an editor on a computer (which is not in the studio). Even if you do not know how to do it by ear, there is a trick.

Here's the steps.
1. Sample the sound.
2. Use the tuning value in the TRIM screen to adjust the root tuning of the note to the nearest semitone. If you sample vinyl at 0% (not sped up or down), it is likely to already be there since most musicians are in tune when they record (however some play a little flat on low notes and little sharp on high notes. It sounds better that way for some reason).
3. Assign that same sample to as many pads as you like.
4. On each pad change the tune settings to -30, -20, -10, 0, 10, 20, etc. Every ten represents one semitone (key). On the XL model, you can just use the Autochromatic assign to do all this for you.
5. Play it.

To adjust the overall tune of all the pads that share that same sample you can go back into the TRIM screen and adjust the tuning. If you have sound module handy you can play a note on the sound module and on the MPC at the sme time to tune by ear.

Or to save yourself a lot of trouble, just buy a full-featured sampler. Things like this are what full featured sampler do best and have more featues. Even a lowly S2000 or ESI-32 has a lot more sampler features than the MPC2000/3000.

people....

all good for the info

so does no one copy the note, tune it up by +10 or so and then time stretch it back down to the original bpm to get the different notes?

Are you talking about changing the key of a loop, but keeping the tempo the same?

A way to do it (without timstretching) is to chop up your loop into the separate notes and then you can recreate the loop as a MIDI sequence made up of these individual notes. You can then tune each note down, say -10 and this would drop the key by a semitone while keeping the tempo the same (tuning up will create gaps in the audio though). The advantage here is that you can also change the feel and note sequence in the melody to suit your song.
