hi TK, i got the same "issue" with the dual color setup...i tried to use normal leds, they are reacting very strange, like , when i switch to track 3 then 3 leds lit up, T4-> 2 lit up... is there a way and a "how to" to change the behaviour of the pinnings , so that they will behave like all other leds?...just to put single ones on there?...since im no programmer, but i learn every day a bit more ;)
