After having worked quite extensively with mapping the QuNeo's LEDs, I feel like it would benefit from at least the following two changes:
1) Currently, banked sliders/rotaries do not have the ability to be linked to separate input channels per bank (that is to say, I can't control the LED's of bank1 of the vertical sliders separate from banks 2, 3, or 4).
2) I think the midi input scheme should be remappable, similar to the outputs. This would make hacking more user-friendly and generic; plus, it seems like a reasonable capability.
