I’ve seen mention of 1.10B firmware for the DN. It’s not available through the Elektron website as far as I can tell (just pulled 1.10A, installed and working fine 
). Maybe its only been released to beta testers?
I’m curious though, and this is a question for anyone with 1.10B, does it add the Audio Routing page to the Setup menu? The newest DT OS has this page located beneath SYSEX, but I don’t see anything similar in the DN.
The beta numbering is slightly ahead iirc. The B version of that OS if not shown (and if it exists) is in all likelihood another example where Elektron use consecutive letters to benefit internal processes - the OS may be identical to A - it’s academic if you were to find it as the next public release will probably be beyond 1.10 anyway - so i’d sit tight - the latest available on the website is always the best official one to have unless you are testing
And if you are interested in beta testing head over to the Overbridge BETA thread (contains also BETA firmware versions):

An official firmware version may still require quite some time until the Overbridge integration has stabilized.
