Would it be possible to mount 10k pots horizontally and attach some kind of wheel similar to a mouse wheel on the Pot's post. That in conjuction with a row of leds from the DOUT modual could then be used to show the fader position. Touch sensitivity could then be added the same way as a mouse wheel can function like a third button. The touch sensitivity part would require some skill I think, but the the pot alone would be easy to wire up. William
