Technical questions for the MPC2000xl and the MPC2000
By Mr. Messenger Tue Oct 28, 2003 6:56 pm
keep in mind that ive only had my mpc 2000xl for a month so this tip might not be so special.

anyway, heres what i found out (while analysing the shape and pattern of a bass wave form)

{
{ {
{ { {
{_{_{_{_____
{ { { {
{ { {
{ {
{

^^^^^^^^^^^^^
pretend this is the waveform of your sample. because of the triangle shape, it would be hard to make a smooth loop of this sound so that it played continuously, without a pulse or click, like a keyboard (or whatever instrument the sample is)

TO FIX THIS.......
{
{ {
{ { {
{_{_{_{_{_{_{_{_{_{_{_{_{_{_{__
{ { { { { { { { { { { { { {
{ { {
{ {
{

^^^^^^^^^^^^
copy and paste the last part of the sample (or whichever part you want to loop) next to itself many times. instead of looping the last part of the sample and getting a high pitch squeel/ring, you will be looping many copies of the last part of the sample. this gives a smoother effect, as if the original note was continuously being sounded. this gets rid of the pulse

to get rid of the clicks, simply make sure the "ends" of the sample are looped at the same relative spots at the lowest frequency points.
--------
is this something old which everyone knows? or is this new or useful?

is this an alternative to multisampling concidering natural decay can also be achieved by setting the program parameteres decay type to END (with specified decay) and voice over to NOTE OFF?

can i have some feedback i just wanna know if there is a better way than this, cos i dont wanna do shit the wrong way.

peace

Yeah this is basically how most singleshot loops are made.
I'm glad you figured it out so early on with only 1 month on your MPC.

Good post though for those who aren't as clear on the subject as yourself.

There is no wrong way to eat a Resses!

ok im glad its a helpful idea to beginners!

i need a tip now.....what is the quickest way to make the multiple copies of the end of the sample and paste them perfectly along side one another?

"insert sound""?

dudde...

When chopping up samples with that type of precision....I use Soundforge or CoolEdit...simple copy/paste/stretch, etc.....i think on the MPC its that "insert sound" function..but i rarely do it on the mpc..so im not sure.

I use Sound Forge or the MPC depending on how I feel that day.
My normal preference is Sound Forge though.

Sound forge too. I never tried to loop a bass sound on Sound forge yet but on the MPC I always get the click sound.

Clicks and pops come from sudden volume changes in the sample.
For me it's best to find a start zero crossing point after the initial attack and then find a zero crossing point at the end of a cycle and your sample
will not pop or click. If you hear the clicks and pops then adjust either start or end in VERY small increments until it disapears (all while listening constantly to the sample in loop mode of course. That is described in Tutorials for sound forge on this site. It's exactly what I've been doing all along.

lampdog....that is the exact method i use to get rid of clicks too. i use the mpc though

thanks for the help people. are there any other methods which make the sample sound EVEN MORE real when it is looped?

I don't understand the EVEN MORE real thing. Once it's looped perfect or as close as you can get it that's a real loop aint it? How real can you get? I don't know. The wave editor can be more accurate (automatic zero finding also) when searching for zero crossing points and actually zooms in to show the samples per second points which is also very helpful. Sound Forge is my favorite wave editor and there is also a tutorial for it on this site which I've read and it's dead on point.

i tried doing the copy and pasting on the mpc but it is not even close to being precise or not. i tried it in WAVLAB and it works PERFECTLY. so im gonna be doing my "multiplying of ends" in wavlab and my looping on the mpc.

when i said MORE REAL, i was refering to the fact that when this method is used, the note of the sound is STRICLY constant (because the end is copied repeatedly) and, for example, string slides cant be extended.

I've had my mpc for almost 2 months, Thanks for the tip I've been having some trouble with looping! Good looking!!

They can be time stretched to a limit, after that they sound unnatural.

yes thats true. i have been experimenting with the time stretch and i can sometimes get it to sound good.

thats one thing i miss about my esi-32 sampler ,the crossfade loop button.usually got rid of the clicks and pops

They can be extended but it's way harder cause you got find a reasonable section of multiple cycles within the wav and copy those just like you would do a loop, you know with the zero crosspoints and all. Most of them will probably have you frustrated and you will quit before ever getting what you wanted out of the whole experience.
