Can the QLC+ source code be adopted so that the GPIO flank detection behaviour changes?
Now it is only detecting rising flanks. Despite pull up / pull down settings in the GPIO (BCM) configuration, you cannot detect or use a level change on the inputs.
With a simple physical switch (low -> high -> low) QLC+ is triggered by the low -> high state and then you need an extra low -> high state again to change the bound input in VC.
You cannot use a simple switch to control QLC+ at the moment, due to the lack of detection of the lowering flank.
On that note: the possibility to create an input-profile for GPIO's (and the possibility to 'generate extra click' in input-profile albeit I doubt this will work without a lowering flank trigger)
