What up everyone! I'm back. I wanted to first let everyone know that I am very impressed with the way things are going here! KEEP IT UP! Its always nice to visit my mpc fam and be greated by new samples (thank you patalinda). I also saw the video that sparq made for the "jessiah glitch"... it motivated me to make my first (of many?) instruction videos specifically for mpc-forums.com. I really wanted you all to see what the glitch is all about, and then mess around with it. I hope the new OS doesn't ruin it, but it probably wont (I cant wait!!!!) I heard this glitch works with other samplers too... This glitch may have been discovered already but I found it independently. Lets call it the Jessiah glitch for now :)

http://www.megaupload.com/?d=3GJH8QFW

Its a big file, so go make a sandwich or something... I will also write out the exact steps as simple as possible:

1. Load at least one sample. (you can experiment with multiple samples, and also short/long samples)

2. Go to the TRIM page and select the main sample you want to "glitch".

3. Set the START to 0, and the END to 1.

4. In the TRIM page, set the LOOP to ON.

5. You can now preview the "glitched" file! Hold down PAD 13 and it will play the sample at a lower quality bit sound! It will repeat this sample if you hold the pad down for longer than the sample. It will also mix in other samples that may exist in your memory.

6. If you adjust the END value to 2, you will notice that the pitch is effected AS WELL as the sound/bit quality. The closer you get the END value to 31, the lower the quality and pitch get. 31 is the last value where you can still hear the sample, its almost unrecognizable though. Once you get to 32+, the mpc will only play what that tiny 32 samples sounds like. Also play around with these values because you can make some cool synth kinda sounds.

So you can't save the glitch file... it can only be saved and used if the original sample is in the memory still. What you can do is create some crazy sounds and then record them into ProTools, etc... You can even add effects for some insane sounds! Please experiment with this. I have actually taken drum samples and glitched them... then recorded the slightly lower quality/pitch drums into my computer. Then put this new wav file back onto the mpc and raised the pitch back up... This basically reduced the quality of the drums to add some grime to it. Get creative.

Let us know what you have discovered with this cool glitch! -Jessiah

How the hell did you discover that?

nice intro man. nice glitch. i noticed a few time when im playing around, i get samples in memory to play in reverse, starting with the last sample loaded to the first. hmmm. figure that one. if i knew how i did it the few times i did, i could implement a reverse feature right there using record from main out and trim. damn.

you'll need to experiment... what are you usually doing when you get that reverse glitch???? if maybe 10 of us try the same stuff were bound to figure it out! -Jesse

Nice work on the video, Jessiah.

Nice glass piece too. 8)

i've been lurking on this shit for a minute but i do have to say damn that shit is ill...

seems to play the sample(s) after the "glitched" one in order they are in memory. i just loaded up some songs i was working on and got some really wild shit.

about to record all this bullshit into live and make some noise.

thanks for the tip...

I'm afraid the glitch won't work with the new OS. It doesn't seem work in Sparq's video... :cry:
Check out these 2 threads about the glitch:

i tried it again last night while i was watching your video (which was done nicely) and it still didn't work. i tried a long sample, short sample, a one hit sample, and the only response i got was that high pitch tone. from end point 36 all the way down to 1.

Yeah, i asked Jahrome to check it on the 2500 some time ago and apparently it didn't work on that either.
The high pitch tone you're hearing is the short loop. With the OS 1.0.7 that short loop wasn't working properly so you'd hear the glitch.

hi there!
this is weird, Ensoniq has that same glitch in their samplers! :o
My Ensoniq EPS16+ behaves the same way. If you set the loop too short, the sampler plays all samples in RAM memory as an wave sequence. I wonder if it does that too in my ASR-10...
perhaps the OS programmer joined Akai when Ensoniq samplers left the market? :idea:

make sure that the sample is on loop, and then either hit the PLAY LOOP pad in the TRIM page, or go to the program and set the loop on and the note on. Let me know if your having trouble with it... the sample should be all looped up and only the value of 1 should be on the trim page. different locations can be selected too...
