The sub 37 seems to be in a permanent boot mode...

The error message "ERROR: Proc. Buff" comes up after step 2...

OK, this error (Proc. Buff) is only generated by the main bootloader, and only when it receives the wrong file, meaning any file other than the main firmware. When you're in the main bootloader, you can only send "step 1" meaning the main firmware file.

There was a brief moment last week when Moog Music posted an incorrect firmware file to the website; in this version, Step 1 and Step 3.syx were misnamed (the real Step 1 file was named Step 3 and vice versa). This was taken offline quickly, but it's possible you downloaded this version and it's contributing to the trouble.

Here is a download of the latest firmware, which I have tested myself and I know that the update can complete successfully:

Another piece of trouble-shooting: There was one customer last week who was having a similar problem with the update seeming to get stuck at the main bootloader/step 1/Proc. Buff error... in his case, he actually had a faulty pitch wheel which was acting like it was held in the up position even when it was not. Because his Fine Tune and Cutoff knobs were at minimum, this meant that when the Sub 37 rebooted after loading the main firmware, it booted back into the bootloader (which erases the main firmware) creating an endless loop. The solution was, after booting to the bootloader, move the Fine Tune and Cutoff knobs back to the middle of their range, before sending Step 1 / main firmware.

Try the above, using the files from my link, and let us know if there's any joy. You can also email me directly at amos at moog music dot com.

All the best,

Amos

I can confirm the pitch bend issue just described, as it just worked for me with the help of phone support. Just moving the cutoff and fine tune during the main update caused it to reboot properly. The rest was seamless at full transfer rate.

Excellent support. Thanks!

I had the proc.buff problem after trying to install 102. I reinstalled the main install 101 and got back online.
now im trying to install the 103 updates but after I power on as instructed with fine tune, cutoff and pitch wheel instructions I get the flash erased message but when I try to send the 103 step 1 update nothing happens. the screen stays on the 'flash erased ready for code' message and there's no midi light action.
I've done the reinstall 101/ install 103 process several times with the same fail. also tried the pitch wheel trick to no avail.
help!

all good. I updated via a different computer and success was had...sweet

An important note about the 1.0.3 update: please read the instructions, they have changed.

We removed the manual power-on step and replaced it with a sysex command which does the same thing.
This is why there are now four sysex files, "step1" through "step4".

Just power on your Sub 37 as normal... send the v1.0.3 step 1 file, and the Sub 37 will reboot to the bootloader and prepare to receive new firmware. When the LCD prompts to send code, send the step 2 sysex file. After reboot, (make sure sub 37 still selected as midi output device, and) send step 3... when LCD goes blank, send step 4.

We are working on an automatic update utility, to make all of this much easier. Bear with us with this multi-step sysex process until then. Thanks for your patience.

cheers,

Amos

These updates are great Amos, it shows us that you're working on the issues, and we can see how thoughtful you are about it, how complex it really is.

I might wait till a oboe file uploaded of some kind becomes available. Mostly because I'm too lazy to hook up any of my synths for firmware updates, having too much fun playing them!

Heya People!

I also have a problem updating. I'm used to the c6 program and thought i had it covered. Have also tried several tips from this thread; Sysex librarian, transfer speeds, usb directly, osx and win, latest uploaded fw, patience, multiple cables. Thanks for helping me gain clarity on the issue everybody. The synth had 101 installed, and I tried to update directly to 103. (should that be a problem? (This is the first time i've got my hands on a MOOG on a regular basis.))
I've got the blank display and all lights issue. I make sure to choose the Sub 37 every time in the sysex librarian, and the two first steps goes well. But when I send the third step the synth/sysex librarian doesn't reset itself, as if it doesn't receive anything of the syx. The ARP blinker holds for a short second, then continues in the same tempo. If i try to send the fourth step after this, it seems like the synth receives the info, but it doesn't restart to it's new state after the transmission. (buhu) Tried both 102 and 103 btw.

I've yet to try to go back to 101 and try the process from the beginning, add some more patience with that maybe:) so i'll try that first and come back with the results. Unless somebody can see where my shoe pinches?
And I'm really happy for the support it seems Moog is providing. Looking forward to the automatic update utility. I'll make sure to raise praise on the wonderful Sub 37 in another thread more suited.

I can´t really help you, but I can say, that this should be no problem. I´ve got my Sub37 also with 1.0.1 installed and the first update I´ve done was directly the 1.0.3 ... Hope that someone (Amos?) can help you without shipping the unit back to service ...

Have you contacted Moog Music directly?

Regards
Heiko

hallelujah!

I got a brick after firmware updating, was really hoping to use my Moog all day Sunday, did anyone find a solution besides messing with the transmission settings as Dan outlined?
