ALWAYS BACKUP YOUR IMPORTANT WORK VIA SYSEX DUMP BEFORE ATTEMPTING ANY OS UPDATES!!
Not that we're expecting bad things to happen, but always better safe than sorry. Just remember, you're never going to say to yourself "Man, I wish I hadn't backed that up..."
We do not recommend using the following MIDI interfaces for sysex transfers as we have had multiple users experience problems with them:
- Native Instruments Maschine
- Digidesign Mbox/Mbox2
- Digidesign 001/002
- CME U2MIDI
Updating the Prophet 12 OS on a PCUpdating the Prophet 12 OS on a MacTo check if the OS update was properly installed, go to the global menu by hitting the 'Global' button and the OS version is displayed at the top of the 3rd column
If your OS update failed:
- Update your MIDI drivers for your MIDI interface to the latest or last known stable version
- Try alternate speed settings: transfer speed settings as low as 25% and as high as 100% have worked for some users when 80% did not
- Try an alternate MIDI interface. The M-Audio MIDI Sport Uno works well here and is relatively cheap
- In Windows with MIDI OX on Windows XP: Try doubling or quadrupling the Size setting to start, and halving/doubling the number of buffers
- Search google and/or forums for the company that produces your MIDI interface to see if other users are having similar problems with Sysex transfers and whether there is a solution specific to your interface
- If you are on Windows XP, try another OS or machine. Although it's not ideal, we have had less problems with Mac OSX and Windows 7. Windows XP has known issues with sysex transfers
