Anything that can be computer controlled, it could work for if built appropriately. As it sits, the midi interface will let it work with about any midi-based device, if the software is written to match. My next step is going to be having it run my Ensoniq VFX. At that point I'll have it be able to switch between the DX7 and VFX at the touch of a button. I've already used it with a DX7 MkI, and a DX21. A very early prototype got hooked into a theatrical lighting system, just because. I only had it wired in for a few minutes, the guy that did the lighting design for that theater really, really, wanted me to leave it. The ability to be able to be so interactive with the lighting appealed to him. As to cost, the sensors themselves would be dirt cheap to mass-produce, the most expensive part would be the display. This one uses discrete LEDs, but I think an old-style, low-res, low cost monochrome LCD would be plausible, allowing more sensors in the same space, and a alphanumeric for labels & such. Most of the circuitry could be replaced by a simple microcontroller, it doesn't require any high-power math or signal processing.
