virtual sidewalk

[INTERANIMI]

Has anyone on this list ever modified a "nintendo power pad" before?  Never
saw one until yesterday at a pawn shop type place.  Got me thinking, I wonder
if it would be possible to alter the pad such as spliceing into the lead and
making it trigger CV's.  To do this however, I'm trying to imagine its
workings and Im thinking that its basically just like a large series of
membrane buttons.  Is this so?  Now to do this, one would have to add a small
power supply correct?  I think 5volts?  Im not sure really what amount of
power and where the power should go, but I have a an idea or two about it.
Anyway there's the fuel.  Anyone here able to contribute to this "virtual
sidewalk" theory?  I think I want to try to route it thru one of my Korg Poly
6's arpeggio control.

Thankyou in advance
