Dario, were it that simple... fact is because these devices are rotary faders (a little thing I designed for a DIY-synth project as detailed on the synth-diy mailing list), the layout, spacing of components is critical. So basically there are 3 very small pcb's orientated: 1 x horizontally, 2 x vertically (1 either side of the "main" board). So actually, its not a case that I couldnt put a 40 pin MCU on there (providing of course that it would still work after I heated it up and bent it round a 180 degree angle), but that I have to split up the functionality into smaller units. The smd maxim chip looks pretty ideal, but its not absotively clear to me if I'll be able to use it to power different devices from the same chip (i.e 2 x 3 digit 7 segs + 1 x 10 seg level meter + a couple of status lights for mute, channel select etc) I'll read the docs later tonight and find out.
