SSL 360 v1.7 firmware includes a fix for touch-sense dropping out when writing automation from the UF1 fader. This fix applies to using UF1 in a HUI/MCU DAW mode.
There is a separate known issue regarding touch-sense not working when attempting to write automation from the UF1 fader in Plug-in Mixer mode.
We are investigating the issue and will provide a fix in a future SSL 360 update.
As a workaround, please configure a Layer of UF1 to HUI/MCU control for your chosen DAW and switch to that Layer when you need to write touch automation.
