I was also confused about this line. Unfortunately My (second hand) MK1 hast already been upgraded to OS 1.45. and Overbridge didn’t recognize my device.
I installed the latest Overbridge Beta including the OS upgrade on my machine and it still doesn’t work unfortunately. Does anyone have an idea about the reason?
The Sysex Transfer seemed to work and also My MK1 shows up in my Mac finder, but it doesn’t show up in overbridge.
I just had the same issue, along with connecting to C6 – except I was upgrading from 1.31 thinking that it would work with overbridge 2.0 (I was wrong), so I have had to cut my losses and say goodbye to a few fun tracks in the process of downgrading to OS1.31 on the rytm. I was able to use Transfer because of the updated software, but had to use SysEx Librarian for mac to transfer the os update when OS1.31 was installed (https://www.snoize.com/SysExLibrarian/), uninstalling overbridge 2.0 using the uninstaller, and installing overbridge 1.15. All of this installing / uninstalling was done from the regular OS upgrade page (not function + on), and with midi routed to usb, with the usb set to midi only. Switched to overbridge mode and so far, so good. Running ableton live 10.
I really would like to use my rytm with overbridge, but need my samples on there! does C6 have an update (or are there other softwares that I can use to transfer samples to the Rytm?
