Newest Prophet 5/10 OS 1.5.2
« on: December 07, 2020, 03:12:20 PM »
This OS is compatible with both the Prophet 5 and 10 keyboard Then Main OS will display as "1.5.2" after the update.

When the OS file is transmitted to the synth a count from 0 to 100 will be displayed on the synth's main display to indicate reception of the OS file.  Once the count reaches 100, a second count from 10 to 0 will commence indicating writing of the OS to internal memory. 

**DO NOT POWER THE SYNTH DOWN WHILE THE SECOND COUNTDOWN IS ACTIVE**

The synth will return to normal operating after the writing stage completes.  Power cycle the synth off and back on to finish the update.

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

To check if the OS update was properly installed, restart the unit, hold the GLOBAL button and press the 1 button.  The 3 digit main OS version number will be shown on screen.

If your OS update failed:

1. Update your MIDI drivers for your MIDI interface to the latest or last known stable version
2. 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
3. Try an alternate MIDI interface. The M-Audio MIDI Sport Uno works well here and is relatively cheap
4. In Windows with MIDI OX on Windows XP:  Try doubling or quadrupling the Size setting to start, and halving/doubling the number of buffers
5. 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
6. 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


**INSTALLATION NOTE: It is recommended to reset globals and clear calibration after loading the Main 1.5.0 OS update.  You will need to re-tune the synthesizer from scratch following the update.

RESET GLOBALS : hold RECORD and press GLOBALS
CLEAR CALIBRATION: hold RECORD and press TUNE

Prophet5 Main 1.5.2:

Bug fix - occasional dropped notes
Bug fix - MIDI clock present at MIDI IN port while powering on instrument causes MIDI IN to not work

New Main OS version 1.5.2 posted!

If you experience a failed update, try reloading the OS in bootloader mode over DIN MIDI (USB is not available in bootloader mode). To access bootloader mode in the Prophet 5/10, hold both the pitch wheel and the mod wheel in the upmost position while powering on. You will then see "btl" in the display, indicating bootloader mode.
