Hello All
The keybed that I used is a FATAR 61 KEYBED I believe it's the FATAR TP7
It can be found in the STUDIO LOGIC SL161 controller. It can be found for about $50 to $120 dollars.
You would have to remove the original keybed from the pa4x. Then remove the contact board and the additional board from the original keybed and install them on the FATAR keybed. This is a simple process really.
It gets a bit tricky is having to drill new holes in the bottom sheet metal of the pa3x/pa4x and align then with the bottom legs of the FATAR KEYBED.
Also you will have to use plastic metal washers glued to plastic spacers with a rubber washer on top (pictured below) and attach them to the bottom of the FATAR KEYBED legs since they are not as long as the original pa3x/pa4x legs. I used 12 legs I believe there are 14.
If anyone is really interested I can do my best to write as many details as I can in a future post.
Thanks
