To be honest I am not really sure what I am doing. The lack of clear documentation means I continually feel like I'm just stumbling around in the dark with this controller (but still think it's a great piece of kit....just struggling to work out how it works).
I am using the universal RX config, but am not sure about the "with the provided blue hand script". All I did was drag the Universal RX snippet into the code block space for the Element 14 System - Setup (No idea if this is the right thing to do...again, no documentation for me to understand how to do this...just going on some advice someone posted on Discord).
But having done that, I have midi feedback from the DAW occurring for ALL and ANY mappings I set-up. Eg. Map the encoder to Pan (using Clyphx), and if I move the Pan setting in Live, it updates on the device, including reset to Centre. If I remap it to Volume on another track (using Clyphx bindings), it instantly updates to the Volume setting on that track on the VSN1 controller....but only the LEDs and the stored value NOT THE LCD SCREEN.
So I am not sure what the limitation is you mention regarding "the only thing that it handles are changes to the 16 auto mapped parameters"....I can get it to handle any parameter...which is great.
The only thing it does not do is reflect that change on the LCD screen.... so thanks for the note about what you have done with Track Colour and LEDs, but I don't want to touch that piece (it's working), it's just the LCD Screen Rx that is not working.
