I am on Beta 2.3, 3D2CCB9.
My Teletype is locked up, through multiple power cycles. Unfortunately I don’t have a backup of the scene that’s running. I do know that I was using a lot of i2c commands in the INIT scene. 4 TXi knobs were controlling the wave shape of 4 LFOs on the TXo.
When I power the unit on the screen comes up normally, and I can see that the TXo is outputting the LFOs. They are, however, unaffected by the TXi knobs. I can get to the bootloader, so I’m sure the button is still working. I am guessing that I should just reinstall the firmware, but I wanted to ask for advice here first.
Any ideas? @bpcmusic @scanner_darkly or anyone else 
EDIT: details…
There are 8 connections on my i2c bus. I am using a powered backpack, and the runs are fairly short. Also the TX modules are running the latest firmware.
