Vailixi os question (what exactly is it?) hacked os? new os?

i was wondering if any of you could shed some light on the vailixi os fo the 3k, is it a whole aftermarket os? i got the jist that the guy kinda fell off the face of the earth and some people never got their OS when they ordered, does this mean that finding a 3k with the os already installed is pretty hard now?

also, if he made an os from the ground up, or modified the akai one, could it be possible for someone else to implement full mute groups like in the 1k and 2500 into the mpc 3k?

how exactly did this OS come about, the guy wasnt affiliated with akai or have the original source code did he?

couldent the 3k be pushed much further if writing an OS for it was that easy? why wasnt it tried again by someone else?

Hard, yes, impossible, no.

But you will pay a premium, check the completed sales on the MPCHunter site.

Beat me to it ^^^


Also, I think it's fair to point out that something like building an OS like this (singlehandedly, to boot) is no easy task. Otherwise, wouldn't we have 1,000 JJ's and Rohans?

what could i search for for keywords? i just wana know if it is feasible to think someone could build the os from the ground up or not; or if this is what he did.

didnt really wana try and search through all of the dudes posts to find out if he used source code from akai or if he built a whole new OS himself or with a team.

@b.read, i realize that it would be hard to build an OS single handedly, but was wondering if he did this, why doesnt anyone else attempt it? seemed like there was enough interest in his os after the fact.
if he just added onto the akai os, wouldent this be a much easier task for someone to do, or even maybe add onto his OS.

i looked on his webiste and couldent find the answer and from what i have read, the website was just auto updated so contacting him about this (or future updates) is out of the question.

in the end im just confused on how this OS was born, when i see other people ask about OS updates for different mpcs and the answer is always "its impossible unless akai released the source code for it"

but from what i gather, akai never released the source code for the 3000 and for some reason we have vailixi OS.

If you want to find out any info, this is what you'll have to do.

Don't know if Rohan was minded to share this info, its his cash cow.

I've got a Mint MPC3000LE with internal zip drive and with Vailixi installed. $3,000, it's yours.

Lol.

And that's not including shipping & handling. Lmao

Make It an even 4,000 then just to round things out.

Step right up gentlemen! I will sell my regular 3000 with internal card reader and Vailixi for $3000 and include the shipping! Takers? Takers?

Vailixi was not written from scratch..
He removed all the help related code/strings.... so that he could jam his extra code in there.

There are various ways to hack extra functionality into an embedded system like this.. but basically if you don't know how to code in assembly you're s*it out of luck... if you know nothing about that, lets just say that most modern programmers can't code in assembly... let alone reverse engineer any of it. (it's a dying art) ... There are many books you can read on this if it interests you..

To get the binary data of the firmware into human readable assembly code you use a 'dissembler' ....
A popular choice is 'IDA Pro', you can also use a hex editor to do some simple reversing, like changing strings(text) and messing with offsets.... you could experiment with reversing simple things first like when you press the load button on the mpc it will show the save screen instead ... I'm sure you can figure out how something simple like that would be achieved ... with enough patience & experimentation.

Basic reverse engineering like that is easy...
But to add/change the kind of functionality as was done with Vailixi requires the ability to first figure out what the os is doing.

So you figure out what CPU the mpc uses.... and select that in IDA and disassemble it.

Now you need to know how it works before you try reversing it.. this is where is gets hairy... it's very tedious and requires alot of time and effort, experimentation etc.. the kind of programmers that did games before the ps1 would be the types that would find something like that not so hard... but the biggest thing needed for reversing these kinds of things is motivation/drive... and that's not so high when the reward is low.

I thought about reversing some stuff in the 4k os... but honestly it's not worth the headache....
....And up to now no others have stepped up like Rohan... so they must feel the same way..

szr, thank you for the extremely informative post. thats what i was looking for

now to find someone who can reverse engineer something

not for me.

sorry guys, if you added full mute groups to that shit, i might consider buying your 3k from you

thats what i really want in the end. a classic mpc sound with a newer mpc workflow. looks like its out of the question unless i turn into a genius overnight.

The mute group thing isn't that big of an issue....and that's me coming from a 4k where I constantly use mute groups. Just takes a little more time and tricks on a 3k to get stuff ''right''. Leave a pad to note off and just hold each one while your drums are playing and then you will know which ones to assign to the mutes of each pad.

MPC Renaissance + Vintage mode = classic mpc sound with a newer mpc workflow?

sig worthy

@sirparksalot, yeah i know that, i just like banging pads as opposed to holding them.
