it was on the same site, waaay back in the day (early 2006? mid-late 2005?)

some guy had been googling and found it. i remember all this very vaguely, and i think jj mentioned it one time in email. they were basically 2 "application os's," one which was all about pitch. using the qlinks you could do stuff kind of like this forwards/backwards adsr addition. i never installed it - can you believe it? back then i was afraid of 3rd party software somehow damaging my MPC. there was a little excitement about it and some predictions were made by now long gone old time forum prophets.

anyway enough talk, i've gotta install .80 and give it a whirl.

whoaaa....this is wild. it took me a second to understand. set it to 0.0k on a sample (in this case one of those stabs i was talking about in the other thread) turn the pitch adsr depth up to 120 and set the pitch adsr attack to 0, set the decay to something short, and sustain all the way to 0

tap the pad as you bring the decay up. lots of playing around here. you can do some weird things with short percussive hits, like a hat that pitch bends from 0-120 as you strike it...

heads up - UNDO now effects the renaming of tracks, ie if you have TRACK1 and rename it HORNS, then hit undo, it will go back to TRACK1. i don't think it was this way before.

i thought the pitch env did this anyway....is there more to it than the bend? just curious, im wandering why jj has categorised it in terms of sample rate, i mean, all a sampler ever does to pitch a wav around IS change the sample rate, but described rather in terms of semitones.

pitch env did that, but with not as much control over the direction in which the pitch is going. plus this gives it a "start rate" of 0.0k, like hitting a turntable's play button from rest. also you have the added control of the decay and sustain of the pitch envelope.

the language here is strange, why use 44.1 khz and 0.0 khz as "speed" descriptors...i was confused when i saw that, but it makes sense now. it might as well say "normal" and "from stop" or maybe "normal" and "-infinity" but i dunno, that may be just as weird looking. regardless it only takes the flip of the wheel to figure out what the hell is going on there. pretty straightforward.

Awww you never tried 'em? Too bad, they're fun programs, though of limited use. Not quite stable, either. I still have them. Here's some corrections to your foggy memories:

I first found the JJ site a month or two before it was announced on the forum. It was right near the top of the Google MPC1000 links. Originally it was just a proposal for new software w/no downloads. I swear that site was there almost the day the 1000 was introduced (which might back up the rumors as to where "JJ" came from in the first place).

Then came the downloads, there were actually four of them:

mpc1000ex.bin -- this was just Akai v1.07 with a bit of extra code tacked on the end to facilitate loading of the alternate OS programs by holding a key (was it FULL LEVEL? it's been awhile) on power up, similar to the OS1/2 switch except that the "alternates" were loaded from the root of the flash card instead of internal memory.

ms1000.bos -- don't remember what the "ms" stood for, but this was basically a utility program for working with external midi modules. I think it had some file management and editing features as well.

wp1000.bos -- the name was "wave prayer" This was a simple, non-destructive chop routine; the basic function that everybody was begging for before OS2, though very basic. To use it, you would load up an extended sample (I used to just drop in an entire d&b track) which would you could play back in it's entirety with the transport controls. You would then have the option to zone out different parts of the sample and each zone would be assigned to a pad. Additionally each pad zone could be set up to play forwards or backwards and at any speed you wanted. It didn't do much more than that, none of the "normal" MPC sequencer features were present and the interface was completely different.

vc1000.bos -- "voice changer". This was the proposed "deluxe pay for it" version of "wave prayer", but the project was shelved and as far as I know a full, unlocked version was never made available, free or otherwise. It had a timeout and was the least stable of the three. It was almost a game to see if you could beat the timeout by going crazy with the thing to the point of a system crash. So what was cool about it? It did everything "wp" did with the addition of both realtime pitch-shifting and pitch correction via the q-link controls. I'm not sure it did "true" timestreching, but this was still a HUGE slap in the face to many of the Akai-huggers on the group as well as some "official" Akai reps who claimed that the MPC hardware was not capable of this kind of realtime control (remember this is back in the pathetic V1.xx days, just before the bankruptcy and buyout) and that we should be eternally grateful to Akai for giving us what we had an to kiss their butts forever etc.

Actually, my memory is a bit foggy too and there may have been some additional features to the 3 "alternates" (not really plugins in the true sense of the term) that I've missed here and I'm thinking about loading them up again just to refresh my memory...

BTW if anybody wants to dig for more info, there's always the web archive snapshots of the "JJ" site to start with, though of course they're incomplete:

awesome, thanks for writing that. you must have been the "some guy" i described above. those were exciting times, less so than now but i guess the excitement has become standard and i'm desensitized

No that wasn't me, but I remember the post you are talking about. I think it was somebody who had a slight grasp of Japanese, enough to figure out what the page actually was and grock the instructions. I didn't actually install it myself until after that post. It's still somewhere in the archive...

Really interesting history... I've often wondered how this whole thing got started. I don't blame you guys for being afraid to load these early versions, but my how times have changed.
Anyways... I was hoping to get some help. About this turntable start type of effect? Could one of you walk me through it? Or at least give a few pointers? Thanks in advance
This may just push me to buy V.2 ASAP.

Oh, I just got it... I like this. Is there anyway to have it slow to a stop?

By earwolf Wed Jan 09, 2008 9:22 am
people have been after that turntable brake/tape stop effect for years. i know there's vst's specifically for this these days, but even so, seeing it turn up on an mpc is cool. I expect os2 0.89 to have "rEmOvE vOcAlZ fRoM dA tRaCk bRuV" function, thereby killing 90% of the newb traffic overnight
