Technical questions for the MPC2000xl and the MPC2000
By Mick Swell Thu Oct 21, 2010 3:15 am
So I sampled a base note from a synth and looped it. When I hold on the pad to play the note the note plays and loops but when it starts to loop I can hear a click, sort of like a quick pause, and the note plays again. How can I make the bass loop be endless and continuous when I hold on the pad as if im holding down the keyboard and playing the note endlessly? Thanks!

play with the ADSR of the sample... increase the attack and decays and keep trying till you get a nice overlap...

Either that or timestretch it a bit.

When looping single bassnotes you'll have to set the loopendpoint near the end of the sample, than set the loopstartpoint just few cycles (something between 2 and 7 cycles) before the loopendpoint. Its very important that the looppoints are set to zerocrossings. If you hear clicks one or both looppoints are not exactly on a zerocrossing.

this is all about zero crossings and learning how to loop cyclical waveforms properly.

the point is, the beginning of the loop has to be almost exactly the same as the end, and i'm talking on the sample level. this is why zero crossings are so important - if it starts on a zero crossing and ends on a zero crossing, there will be no 'click' as the waveform tries to jump from one value to the next.
Think of it like a wave...a natural sound follows a wave pattern and, even if it's very fast, it eases from one value to the next. This is especially true for bass notes where the waves ARE actually slow.

Try to keep your loop as short as possible, trying to loop only one repetition of the base timbre of the sound.

Another trick you can try, is to take the loop, copy it to a new sound, reverse it, and then paste it right at the end of the loop. now make the loop cover both this forward and backwards traveling of the wave...however this technique is more useful on pads and strings.

TLDR; Find the absolute shortest section of your wave that repeats, and loop it with the start and end points both on zero crossings.

Okay so I understand the zero loop crossing. Is there a menu for that and how to do I get to it on the mpc 2000xl THanks.

open window on start / end point
zoom in as far as you can
just get it close to the horizontal line in the middle as possible

no there is no 'auto zero crossing' feature

fortunately we were born with an excellent tool to fix this problem... our ears.
