OB-6 OS - 1.2.0

OB-6 OS - 1.2.0
« on: March 08, 2017, 10:59:14 AM »
This OS is compatible with both the keyboard and desktop module; it will display as "1.2.0" after the update. The OS update may hang on "1" after the second countdown. If the OB-6 does not reboot automatically after the second countdown, wait 60 seconds and then power cycle.

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 6 OS

To check if the OS update was properly installed, restart the unit and the version number will be displayed on startup in the bank/program LCD

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

INSTALLATION NOTE: It is recommended to recalibrate the filters and reset globals after installing a Main OS update. These functions can be found in the globals

Main OS 1.2.0
  • Fixed bug: Resolved a fringe issue causing a very small number of units in the field to intermittently fail to produce audio or to have static noise in the digital effects
