MPC4000 OS 1.8 Beta
My modified operating system for the Akai MPC4000. Version 1.8 adds three things I always wanted on this machine. It is a beta: not everything has been tested yet.
- Akai MPC4000
- Version 1.8 beta
- Software modification
What's new
Slice into up to 96 regions
Samples can now be chopped into as many as 96 regions.
Direct input monitoring
Monitor the audio inputs directly from the RECORD menu.
Audition while the sequence plays
Listen to audio files from the LOAD menu while a sequence is playing.
Not fully tested yet
This is a beta version of the firmware. I can't check the full functionality of the OS myself — there simply isn't enough time.
My MPC4000 also has no expansion boards installed: neither the analog outputs board nor the ADAT board. Everything related to them is untested.
Tell me how it works for you
I'll be grateful for any feedback — bugs, things that behave differently from the stock OS, results with the expansion boards, or ideas for the next version.
How to install
- Download
mpcv18.bin. - On a Mac, open MPC4000 Loader, click Choose… and select the downloaded file.
- Click Check to confirm the MPC4000 is detected, then Flash OS.
From Terminal the same is done with:
./mpc4000-loader --firmware mpcv18.bin --yesYou install this firmware entirely at your own risk. This is a beta version of an unofficial modification, not an Akai release. By downloading and flashing it you take full responsibility for the result — I can't be held liable for any damage or a non-working MPC4000.
Things can go wrong during an update, for example:
- a poor-quality or damaged USB cable;
- the connection being interrupted while flashing;
- the MPC4000 or the computer losing power or going to sleep;
- an incompletely downloaded or corrupted file.
Flashing erases the MPC4000's flash memory before writing, so keep it powered on and connected until it finishes. Before you start, check that the downloaded file is exactly 4,194,304 bytes.
