Would you like the MPC Renaissance support JJ OS programs an

there's absolutely nothing in it for JJ. all it will lead to is more people abandoning his OS & the 1000 (maybe not right away, but over time) and moving over to the REN. that's nothing but decreased sales for JJ which eventually means less support & attention for the JJ OS.

JJ should just keep doing his own thing.

+1 billion

thats what i was wondering???? is the format really that secret? or was that a:

"lets put the success of this feature request in jj's court and make it appear like its his descision, and if he doesn't go for it, users cant be mad at us cause its not our fault....jj wont share his format! "

Please take that with a grain of salt.....I dunno enough about the formats......I don't want to come off as 'conspiracy theorist guy', but hey! it adds to the discussion!

Because that would sound silly. Everybody has seen the videos buy now. Flux and Saint Joe (who have not chimed in on this thread..by the way), asked Dan about JJ OS support....saying Akai should support all MPC users. Personally, I do not care if the MPC Ren could load JJ OS programs or project files. There is no benefit to me and it certainly won't stop being from buying the JJ OS.

MV-8800 and Maschine can load Akai MPC Program formats. Many hardware samplers can load the Akai S format. This didn't not negatively impact the sale of Akai MPCs and samplers...as they are the last company still making hardware samplers.

I've done a bit more reading, seems that its possible to work out the structure of a file using a hex editor, assuming you understand binary code, and have lots of examples of the files so you can work out which bit refers to which bit. One article I read made it clear that this was no stroll in the park, and involves lots of tedious work. It also suggests it may be illegal to reverse engineer files like this.

For a start though the standard MPC1000 format is already well documented:

Thx for sharing, going to look in that later.

On the topic, I'm not a programmer, but I hardly imagine giving PGM spec to akai would tell them anything about it without having source code for OS. So some of you want to work on Ren with jjos seq and pgms.. almost flawless. That's OK. I wonder HOW you want achieve this without having appropriate features in Ren soft in the first place. As someone said.. most settings will be lost or ignored if they will not incorpoate correspoding features. In jjos sometimes programs do not translate well to sequence between updates, not mention older OS versions.

there is reverse engineer files, ofcourse.
you put values ​​to the parameters to search, and looking for changes to the PGM file, You can find the new parameters added by JJ and with help the PGM structure.

it involves lots of tedious work, yes, but is possible.

about may be illegal to reverse engineer files PGM, i think that copyright the PGM format is for Akai, not JJ.

if akai want the ren to play jj pgms, they should add altloop and crossfade loop,make sure pads are chromatic, and leave it at that.

the alt loop, x-fade loop would make it better than the mashine for creative sampling from the off, but i agree with sooty- everything else would be a stretch if you wanted everything to play correctly.

Everything you are saying can be said for the MPC 4000 and 5000 as well. While the MPC Ren can load files from these MPCs, programs will not sound exactly the same because several parameters from these MPCs may not make it to the Ren.

maybe jj should ask akai to trade knowledge for access to thier controller. that way he can finish jj sequencer and we can use the mpc ren controller!
