MPC Operating Systems - MPC OS Updates

Akai MPC Operating Systems

An MPC operating system (or MPC OS) is the software that actually runs all hardware MPCs, and is also referred to as the MPC firmware. After the release of each MPC, operating system bugs were usually discovered by end users, so new operating system versions are released over time to fix the reported bugs (or to add new features). If you are experiencing any bugs or problems with your MPC, ensuring you have the latest operating system should be the first step in the road to (hopefully) fixing the problem. However you should be aware (based on the bug reports on MPC-forums.com) that most MPCs running Akai OS still have some bugs remaining, especially the MPC5000, and some bugs may arise purely from hardware problems inherent within your specific unit, so not all problems will be solvable.

Akai MPC Operating Systems

These are the official Akai operating systems  – note that the MPC60 OS is not available as a standalone file as it is hard coded into the unit’s ROM chips. You can download the ‘MPC Software’ demo versions for Mac and PC from the Akai Pro MPC web site.

Model OS
MPC1000 2.13
MPC2500 1.24, 1.23
MPC5000 2.0
MPC500 1.31
MPC4000 1.71
MPC2000XL 1.20
MPC2000 1.72
MPC3000 3.11
MPC60 2.12 (N/A)

JJOS Operating Systems

The JJOS is a third party operating system for the MPC1000 and MPC2500 only. It is apparently developed by one of the people behind the original MPC1000 OS. It comes in a free version which fixes all the outstanding bugs in the Akai OS for each machine (as well as adding some extra features, such as improved disk management). There is also also several paid versions, which add progrssively more advanced features. OS128XL is the special OS for the extra large screen modifications from MPCStuff.com.

You can find out more about JJOS at the two JJOS sites, JJOS MPC1000 and JJOS MPC2500.

Roger Linn, original designer of the MPC range currently offers an updated OS for the MPC60. Mansell Labs offer an MPC3000 upgrade called the Vallixi, however you should read this forum topic before buying.

    First of all, I’m grateful that you exist. In my once per decade search for things MPC60/3000 related, I’ve never seen a site so well organized and maintained. Thank you.

    My question has to do with updating the MPC3K operating system. And the question is, can one go from say the oldest OS, to the newest OS, bypassing any Operating systems in between? Since I don’t recall EVER updating this OS, seeing the “latest and greatest” available here, the temptation is to simply download the latest OS and load it up. Is there a flaw in this logic? Thanks much for your response in advance.

    Actually I need to update this as there is a 3.16 version of the MPC3000 OS which was created by a third party (Rohan Mansell), but is actually free. But only free if you download it, transfer to floppy and boot up from it via 3.11. Best option is to get it on a ROM as it frees up sequencer memory (but ROMs cost money). More info

    But if you are booting from floppy, you can choose to keep switching between different OS.

    Here’s the 3.16 OS:

    hey guys i really need help!! im going crazy over here!!! i purchased an mpc2500 that had an old version of jjos, while trying to save something it froze & now i cant access the internal memory or save anything at all. it will only let me load sounds from the cdrom or memory card. i read up on the forums & think the problem is i need to update the jjos to latest version. problem is the install instructions i find are for people who are going from the regular os to jjos. it tells me to hit f4 which is usb but on mine usb is f2, also i have a mac & the instructions are for pc. im really pulling my hair out on this one. i just want to play & save my shit man. this sucks:((((( plz help plz

    Thanks much, this site saved my ass.

    For those of you having the boot up hang/freeze issue with the MPC2500. You can download the original mpc2500.bin file here and install it on a CF card at the root level. (I used my mpc1000 to install the OS on a CF disk and then was able to boot it up in my 2500.) After you get your machine to boot, you can then sort out your JJ OS reinstallations to get back where you were. I used the 32mb Akai “Bonus Track” CF that I believe came with the MPC2500 but I don’t remember as I have had a bunch of different machines over the years.

    Just wondered if anyone else had these issues. On the MPC 2500 original OS on hitting PLAY START my external drum machines (707 & 606) don´t trigger from the beginning so the two drum machines are in sync with eachother but not the MPC sequence. So, i updated to the JJOS 3.10 and that problem has been fixed! However when recording a MIDI sequence with my JX3P the notes cutoff at the very beginning of the pad let´s say. When i press PLAY START it sounds fine. It´s when it loops back again to the beginning that the problem occurs. It´s nothing to do with Note ON or Note OFF messages. I triple checked everything. But, when i reinstall the old OS, that problem has been fixed but then as before my drum machines are out of sync. The only way they sync is by pressing RECORD + PLAY START. Very strange. Any advice? Thanks, Paul

      Could be a number of causes, loose connection inside (hard drive, display etc), bad RAM, faulty hard drive, main board fault, etc. If it’s new, send it back.

      Open her up and check all internal connections to the main board are sound and seated correctly, i.e. hard drive, screen, pad sensors, etc. Also check the memory is seated properly – also try removing it completely.

    We just got a MPC 2500 out of a pawn shop. It looks and works fine except for an annoying buzzing noise when its plugged into speakers. The buzzing noise also records when we try and track it out into pro tools. Would updating to JJOS solve this problem or does it need to be repaired? Please help!

    Is there a JJOS for the 500 (if not why)? Are the rumors of the JJOS for the 1000 working on the 500 true? Can you update the screen on the 500 to a larger screen to possibly work with JJOS?

    Hi, I have an MPC2000 that I bought brand new in ’99 that has never given me any problems. It works perfectly still to this day! What are the benefits to changing my original OS to the JJOS?
