According to Gregor at http://www.synth-parts.com/

"fatar contactrubber will fit in most fatar keyboards. They use allways same typ."

Fusion 8HD keybed consists of two circuit boards - The part numbers are most likely FATAR part numbers not Alesis
Part number on the PCB 02.0188-A 26613400 with 49 contact pads

It seems the rubber contacts come in either 12 or 13 contact pad strips with groups of 4 contact pads and can be cut to any odd number of contact pads needed.

Fusion 6HD keybed consists of two circuit boards - The part numbers are most likely FATAR part numbers not Alesis
Part number on the PCB ? with 29 contact pads
Part number on the PCB ? with 32 contact pads

THAT is good news Jesse . . . . .

I mean . . . REALLY! - WHY would anyone want to reinvent a wheel that is already made? . . . .

Worthy of note, is the fact that there is a wrong and right way round when fitting them - (although they look

symmetrical and reversible . . ) They're NOT.

There is a slight difference in height between the Pairs. One contact triggers the note, the other creates the time delay

on release (or something like that). Reversing them on the pcb will totally mess this up . . .

Although I didn't try this - it seems extremely possible that they WILL mount to the pcb the WRONG way round . . .

SO - look carefully at them before you remove anything - so you KNOW the correct way round. . . . :lol:

[BTW - I've replaced the pics at viewtopic.php?f=13&t=6852#p36017 ]
