could i use the adsr and altloop feature instead of timestre

do you guys ever use the adsr and altloop feature instead of timestretching something so you can chop/psudeo stretch/ and create a beat all in your mpc?

nym posted this video here about it and i had never really given it too much thought until today.

this is the video that got me interested in this feature
he is doing it on an mv 8800, although he says the release feature in the mpc works similar to this.

although the release feature isnt what nym is using in his video is it?

i really want another hardware sampler now and if i am correct in assuming this feature will work kind of like a timestretch then i can just jam out on pads instead of be confined by my mouse.

the reason i ask is whenever i chop a sample, i will then go back and timestretch each one so each beat is exactly the same lenghth, but i never wanted to do this in the mpc before because of the shitty timestretch algorythm. because of that i have always thought it was best to be confined to chopping on my computer.

any help would be greatly appreciated.

I don't know which mpc you have, but JJOS for mpc1000/2500 has alt loop. JJOSXL also has X-fade loop.
So, you just set your sample with an alt loop and then play with the ADSR.
I use it all the time on samples that are too short.

i actually dont have an mpc anymore, im kinda on the fence between a mp and an mv.

so you can use this to match up exactly the length of the bpm you set? do you do this alot to avoid timestretching?

and im assuming x-fade loop is just a better version of alt loop that helps you avoid clicks without even playing with the adsr as much?

thanks for the info jimmie.

The end of the hit just loops till the next beat hits. The time is usually short enough that you don't notice it too much or it sounds good. It just adds a bit of air usually so there is no abrupt cutoff.

I've never timestretched. If there is a need I might layer a longer sample underneath (with SIMULT) and get rid of the attack, or loop some eq'd air/reverb underneath, or, or.... there are many possibilities and techniques, but timestretching has never been something I've touched.

Yeah, except x-fade is a cross-faded forward loop. On stereo samples it can be hard to get a loop without a click so you can use x-fade. x-fade uses up polyphony but in the latest JJOSXL you can also convert the x-fade to a click-less forward loop thereby cutting down on the polyphony again This was added after a user here requested it. A few days after the request JJ implemented it. JJ constantly updates the JJOS with requests from the users here, which is absolutely amazing of him.

I've never used an MV.

this is awesome! that is really good to know that it just loops until the next sample hits! im assuming that you are meaning the same sample on the same track, so if a kick drum or a snare drum hit while it was looping (provided they would be on different tracks) they wouldnt stop the loop from looping?

thanks alot man, very helpful!

It doesn't matter that they are on different tracks, as long as they are in the same Program you can have any sample mute another.

Any of the 64 pads (banks A, B, C, D) making up a program can mute up to four other target pads.
So, you can have any sample mute any other sample.


or

You can set mute groups, so f.e set pads A1, A2, A4, A7, B13, C1, C5 to Mute GRP1 and they will all cut each other off. You have 32 mute groups at your disposal in each program of 64 pads.


This is JJOSXL.

Also, I never layer samples on pads the AkaiOS way, I use SIMULT which means you can link a pad with up to 4 other pads to play simultaneously. This means you can mess with the filter env, amp env, pitch, lfo, etc of each sample/pad individually.

ooh ok, i totally overlooked that, so if you dont set up the mute groups then in theory it can loop on forever?

i was just making sure that any other note played wouldent cause your loop point to stop playing, because that would kind of suck. i imagine this is not the case though.
there has to be a mute set up for it to stop looping right?

thanks alot
