I understand that PAFL Clear in the setup clears the PAFL audio bus in the mixer.
My suggestion is to make a new tab in the DAW softKeys setup that allow to Clear all selected PAFL buttons that are active in DAW mode.
Since the PAFL buttons on the mixer in DAW mode activates the PAFL in the DAW software via MiDI, there must be possible to just clear those same switches in DAW mode.
Hope to see this in the next Fw update… 🙂
