Prophet is acting really weird after updating 1.2.8

[fr3d]

My Prophet-6 is acting really weird after updating 1.2.8: some keys are dead (not always the same), some unwanted midi notes are played (very low and high notes), the sound is completly changing after a few notes (losing all the cutoff it seems), arp stops on dead notes. All these symptoms are totally hazardous, it can play some sounds well and suddenly, it makes horrible things

I've tried to play the synth from two different midi keyboards.

I've reseted the global settings, and calibrated the OSC and filters as said in the user manual.

Mine was 1.2.0 when received it. How could I downgrade there please?


I've recorded the problems:
(the blanks are missing notes...)

I've opened a ticket at DSI support.

Did you try to reupload the firmware again ?
Or to revert to previous firmware ?

I've been helping Fr3d through support.  From what we've found thus far, it sounds like its a MIDI issue which is unrelated to the Prophet 6 specifically.

Apparently, I'm not the only one with this problem.. I have a Micro Express, and this guy has the Midi Express-XT... but everything was fine before updating. I'll check again the settings after my day at work.

I'm testing it tonight, and everything seems ok now, with the same synth config and midi onterface... perhaps some midi cable was not properly connected..

For now, I'm happy with it!
