Uno Synth Pro : Trouble on installing driver on Big sur ?

Postby WeareAnimals92 » Wed Aug 11, 2021 1:13 pm

Hi,

sorry to bother you but when installing the firmware update for my new Uno synth pro desktop here is what happen :
- Uno synth is detected and ready for update (cool)
- Firmware update in progress ... updating presets (cool too)
then :
- Preset update failed
- Restart the program (holy ****)

Then I try several times and it's always the same message. My uno is blocked on OS UPDATE mode and I can't turn it off or on ...

I'm bored...

Somebody knows ???

I had the same problem, but in my case the Mac started complaining the USB device was drawing too much power from the USB port. That was despite the UNO Synth Pro Desktop (small version) plugged into the mains as well.

What I tried — and this succeeded — was plugging in the USP in a CalDigit Element Hub that delivers 85W on its USB ports, and that worked.

It's a suggestion that comes late, perhaps too late in your case, but if that were to be the case, it may help others perhaps.

Thanks for your reply !

Finally I found a solution by updating my firmware on a MacBook w/ Catalina.

Concerning power supply I fight against the same issue on my Mac. Question, did you try to plug the mini usb power on a 5V ac/adaptater (like an iPhone one) ?

Someone told me that it should works.

I have an UNO Synth Pro Desktop. I too received the "presets update failed" error message when I tried to install the OS 2.0 firmware update to use the editor. I tried 6 different aux power sources, a Mac Mini and iMac running Catalina. Over 20 tries in all. The solution, finally, was to use my work MacBook Pro with Big Sur. It worked! Curiously, I used the same cables and 5v power supply as with the very first 5 attempts. I can't figure this one out and never had such a thing happen before. (Now I need to contact IK Multimedia support to cancel my support ticket).
