Hello all,
Turned my sub37 on after receiving it back from moog (had to get the cutoff filter potentiometer replaced), and the screen was blank (lit but no text). After checking inside the machine to see if there were any loose connections (there were not), I decided to try to reinstall v1.2.0. This did not work, but going back to v1.1.0 did work. Now the screen is showing text again (I hope the sound is okay - will check soon).
I hope this helps somebody who runs into the same issue.
Cheers!
