Turns out I did brick the Prophet.  I sent the Main and Voice boards back to DSI for service.  They're on their way back now.

Just a warning to anyone planning the upgrade;  Read the instructions carefully and do everything in order.... or else!

I'd be interested to hear what are the exact benefits of that update.

I'd be interested to hear what are the exact benefits of that update.

The easiest way to hear the filter effect is:

filter = 12
resonance = 96 ish
keytracking = 64
unison-mode = all voices (no detuning).
osc 1+2 fine = 0
slop = 0

So the tuning should be rock solid. Turn on unison mode. Play a middle C, and then the highest note on the keyboard a few times. The high note should have a chorus effect applied, but not middle C.

My other conjecture about 'less phasing' was just that ... I did not really A+B the two firmwares because I'm weary of trying my luck (sorry to hear about the above poster  :( ) . However over the last year or so I've noticed some very strange variance between the voices (I've been on the beta OS for some time). Sometimes voices 3+4 just don't want to play (hard reset always fixes that). Other times it is clear that the pulse-width is changing between voices (and there is no sequencer applied), sometimes the pitch, etc. I know some variance between voices is part of the analogue charm, and in some cases it is warranted, but I do wonder whether this update introduces some variance in tuning between the voices that creates some phasing / loss of bass even when the synth is tuned to be rock steady. My hearing that the patches sounded somehow 'fuller' could have been emotional after realizing I fixed my filter tuning issue, which was real.

I'm using a three-unit Prophet '08 system (one keyboard plus two modules) with OS Main 2.3 and Voice 1.5 in all three units.  Sometimes I use them all MIDI-ed together and controlled from the one keyboard, and other times I use one of the modules for bass, controlled by a pedalboard.  Since an operating system update beyond this exists, the one I'm using obviously has a few shortcomings.  But I'm content with it as is, and I'm not going to even consider an update.  I haven't noticed any serious problems that interfere with the way I use the instruments.  There's still a touch of popping when PWM is used in mono mode, but it really is minimal compared with the original.  Besides, I've come to accept it more as a characteristic than as a flaw.  The whole P'08 system works beautifully and flawlessly as far as I'm concerned, and I cringe at the thought of either changing it or breaking it up.

Just so I'm sure I'm clear: the filter bug was with the beta OS... to fix it, I had to downgrade to the OS you are currently using and I will stay there. I think you should stay there too given the (beautiful) demos you have posted ... there would be no benefit to you, and it might hurt your sound if you upgrade.

I only wanted the new OS for the arp relatch mode, but obviously, keeping my patches in tune is more important.

Key word: beta.  I totally agree with you.  And thanks.

Hi all,

New Prophet owner here, desktop module.

I was recommended by support to update my firmware as im still on Main1. 4 and Voice 1.2.

Even though the unit recognises and receieves MIDI (as shown by the dot on the MIDI channel page) it does not go into update as no OS LOAD is shown.

What is my next move as its not the MIDI interface surely as i control the device with the same interface, it is a janky USB cable interface tho... Please don't castigate me for this..  ;D

We often do recommend trying a secondary MIDI interface. As mentioned in the original post, not all MIDI interfaces handle sysex well. I would also make sure the MIDI Sysex Global is set to ON. Your synth can be setup to receive MIDI control messages (as you mentioned), but not Sysex - they are different messages.

If you happen to have an audio interface (scarlett, motu, etc), many have MIDI DIN ports capable of handling Sysex messages.
