Title: Newest Prophet 6 BETA OS: v1.6.6
Post by: cbmd on November 05, 2015, 04:39:25 PM
This OS is compatible with both the keyboard and desktop module; it will display as "1.6.6" after the update. The OS update may hang on "1" after the second countdown. If the Prophet-6 does not reboot automatically after the second countdown, wait 60 seconds and then power cycle.

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: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
