I have a foot switch on the FC-12 that, when pressed, will advance custom looping software from track one to track two, and when pressed again, advances it to track three., and then to track four. However, I have no visual way of knowing which track I am currently on (I don't want to look at a laptop while I'm playing, and its off stage). I was wondering if the FC-12 could be programmed so that each press on this single foot switch would change the color on the switch, so, that by color status, I could tell which track I am currently on in the looping software. Is this possible, or perhaps some other way to visually tell what the status of an incremented foot switch is? Or maybe there is an altogether different approach, although I like the idea of using color on the FC-12 switch itself.
