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.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.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).
