UNOFFICIAL FIRMWARENOT FROM AKAI · COMMUNITY BUILDS
Community developers are writing their own custom firmware, also called alternative firmware, for the MPC 1000. This is a selection, not every fork or experiment: we list the projects with a working build and a real following, and check them every day. FW Radar doesn’t host these files and doesn’t send alerts for their versions: each link opens the developer’s page.

JJOS
by JJ (anonymous Japanese developer)
A replacement operating system for the MPC1000: free JJOS 3.16, and the paid OS2XL, OS3 and OS128XL (for the large screen mod) with a much expanded sequencer and sampler, workflow additions and bug fixes. Still updated by its developer.
Unofficial; Akai's OS can be reinstalled. Hold ERASE at power on after changing OS, or the MPC may freeze. OS2XL, OS3 and OS128XL save only with a paid password (OS2XL US$123).
READ THIS FIRSTAt your own risk, and it may void your warranty. Read the developer’s install notes, back up your presets, and make sure you know how to go back: official 2.13 and how to install it →
Running one of these?Mark it in your rig: the MPC 1000 won’t show as out of date, and you still hear about official updates.
An alert the day a new MPC 1000 firmware ships, by email, Telegram or push
Your whole rig in one place, with the version each device is on
Used and new Reverb prices for your gear
A public rig page to share, if you want one
The Akai MPC 1000 is no longer made, but Akai can still ship firmware for it and we keep checking the official download page. One message per release. No spam, no newsletter.
We pick the ones worth trying: a build you can install and a real following, from GitHub stars and downloads or from the community. Forks that only rename a project or add a few presets stay out, and brand-new projects get a second look after their first week.
Does FW Radar track custom firmware versions?
We note the latest version each developer has published when we check the list, every day, but we don’t send alerts for it: alerts are only for official Akai firmware.
