Exchange tips and tricks for the Akai MPC4000

I contacted AKAI to see if they were willing to release the source code. As silly as that sounds and as improbable as it is they actually do, I figured they were not doing anything with 4000, in regards to updating or re - releasing a new version so I had to ask.

Would be dope if they released the source codes. So we could possibly make a new firmware.

They'd need to release source, build tools, possibly build machine spec, possibly get licensing/permission from third party companies... and a ton of other legal headaches it can be a huge mess. Worst problem is that most companies have little to no financial incentive to do this. I suppose somebody could look into decompiling the firmware, but I understand it has some kind of encryption/checksum on it, so it would require somebody who knew how to create their own decompiler and build chain, figure out the encryption/checksum scheme... etc...

From what I know the 4000 was built by a different team and from it looks like they didn't turn over OS when In-music purchased Akai Pro. Maybe it's out there somewhere in JAPAN, never heard a company deleting an entire OS.


especially not Japanese people/engineers

i will be in Japan (tokyo) in December - who should i address? Where should i go ?

Greetings all,

This is my first post! Finally decided to make an account after years of snooping around this forum :lol: I have used the 4000 for many years. I currently live in Japan. I totally agree with Jawbrizza. It’s extremely difficult to get any type of information/repair service for this particular unit in Japan... I can’t imagine where you would even start as far as getting information for the software. Very ambitious indeed... but I love the idea!

Hi there, same here with the be OS. I wouldn't change 1.71 heavily but here are some things I noticed and please let me know if some of these things already exist.

Reading mp3 format
Found an old hard drive with many gigabytes of mp3 music from the 2ks. Would have loved to use them

Include metronome rate in Autofile
Tried everything, didn't work. I love my metronome being on 1/8 but whenever I restart the mp it's back to 1/4.

Assigns Region to already pre created Programm.
Let's say I sample something and slice it into 8 or 16 regions. To than choose the Programm preferred to have these slices in would be great. Usually always sample melody's and vinyl in mono/ one mute groupe and one shot (zone all)
It's like 4-5 clicks one could save.

Autoplay in audition
When I scroll down the samples in my library to have an autoplay on instead of pushing the audition button each single time

Audition while playing a sequence
Unfortunately the mp does not audition a sample while it's playing a sequence.
That would be great!

Use the enter button to select.
Sometimes after scrolling around somewhere I always instinctively use the enter button to get into a file. That would be great to have that as an alternative to the select button bellow the screen.

A quicker way to get to the metronome
Haven't figured a good way yet. On the mpc 60 it's just a Button.
