I turned on Midi Monitor. If I select something else, like say my DeepMind12, I can see transfer sending sysex to my deepmind (which obviously doesnt respond, its not an elektron). However if I switch to the Digitakt in the list, nothing gets sent over Midi Monitor.

Updates. After getting it to connect on a borrowed laptop with no other midi, it worked fine. I then unplugged everything from my computer and it also worked fine. Finally, I started plugging things back in until it stopped connecting and the conflict is: mio10. Unsure why. Thought this might be helpful to someone out there (either someone else debugging this or maybe Elektron themselves)
