I guess the reason for 12 semitones is that it divides evenly into 1/2 2/3 etc... 3/4 and so on. nice simple ratios that, according to pythagorus. sound most pleasing to the ear. dectaves might be interiesting because then you can do like 2/5 and stuff. i don't thing you would have to reprogram a prom though, cos there are midi programs that change the scale by adding pitch bend.

you should look into some eastern scales, like the frets on a sitar are all individualy tuneable... hmm, who was talking about a cv keyboard with trimpots for each key? could be a good idea!
