OS Download

The operating system is available for download in SysEx format.

Some files may open in your browser rather than downloading. If that occurs:

Mac OS—Control-click the link and choose "Download Linked File" or "Download Linked File As...." Alternately, right-click the link with a multi-button mouse.

Windows—Right-click the link and choose "Save Target As...."

Please note: The Mopho and Mopho Keyboard operating systems are not the same! Download the keyboard OS from the Mopho Keyboard Operating Systems page.

Installation

The OS can be installed using any of the methods discussed in Operating Systems for DSI Products. When the SysEx load begins, the display reads "Main OS Load" and counts down for the duration of the transfer. When the countdown concludes, the display changes to "Writing Now!" When the write is complete, normal operation will resume. Do not turn off Mopho while the OS is writing!

Troubleshooting

Updating the OS is generally very easy, but occasionally there are problems. The most common symptom is that the countdown stops before the OS has transferred completely. This typically occurs because either the data transfer is overwhelming the synth or because some spurious MIDI data (such as clocks or merged data) is affecting the transfer. In the first case, see if you can reduce the transfer rate and/or buffer size of the program being used to transfer the SysEx data. In the second case, make sure there is no other MIDI data on the buss while loading the OS. In rare cases, MIDI drivers have also been known to interfere with SysEx transfers. If all else fails, check for updated drivers for your interface or try another MIDI interface.
