Reply to Controller Hack: NanoPad, LPD8 or Ipad ?

Hi,
I want a customized controller, and I need a row of 12 pads, instead of 2 rows of 6 pads.
The nanopad is made up of a single board for the pads, so I've to split the board, but I don't know if then the pads will still work
I didn't found photos of the interior of the Akai LPD8 or the Icon Ipad, they have a single board too?
I've heard also of a controller by Vestax, can it be good for this mod?
