To display the currently installed OS version: UPDATING THE OS FROM A MAC USING SYSEX LIBRARIAN UPDATING THE OS FROM WINDOWS USING MIDI-OX CHECKING YOUR PROPHET REV2’S INSTALLED OS VERSION Instructions for updating using MIDI-OX and SysEx Librarian are given below. You will also need either a USB cable (Type A to Type B connectors, like a typical USB printer cable) or a MIDI interface to transmit the SysEx file from your computer to the Prophet Rev2.

MIDI-OX (Windows) and SysEx Librarian (Mac OS) are shareware MIDI utilities that can reliably be used to update DSI instruments. You will need a DAW, MIDI utility,or other application capable of opening and sending MIDI System Exclusive (SysEx) messages. The Prophet Rev2’s operating system is updated via MIDI. So if you have any questions or are unsure about what you’re doing, please contact us before attempting to update your instrument’s operating system. In addition, loading an OS improperly could disable your instrument, leaving it in need of servicing. Unlike on computer, the OS on your instrument can never become corrupted, so re-installing your current OS won’t fix a hardware problem, and is not recommended. If you are experiencing a problem with your instrument, please contact our Support Department for help in diagnosing the cause before doing anything else.

Most OS updates fix only minor bugs that most users never encounter. The downloadable file in the sidebar has the latest operating system for the Prophet Rev2 keyboard and desktop module. It also includes the installation instructions given below.
