huumm I see this too, and I’m curious to see how it works! But it’s a P&G product… the best, but not the cheapest I think! I think the led are used the same way as ledring with encoder! But… It may be possible to build this with and encoder!
if you look at the wiring of this device, you’ll see that the led matrix has to be handle by the unit on which you plug it… so I think it’s made to be used as led ring ;D
I don’t konw if this can replace fader as encoder replace pot! But it could be a god idea to use this !!
