Emax

I think I can help as I have experience in this type of membrane contact issue, in particular with my Korg Polysix. The emax uses the conductive pad on rubber for its buttons.  You can try opening up the case, removing the boards to get to the pads.  First clean the pads and the contact surface on the pcb board with rubbing alcohol and a cotton swab.  Then I'd recommend getting what's called caikote 44.  It's conductive paint that you can use to repaint on the pads on the rubber buttons and costs about $10.  After that you should have no problems for a long time.

Check out this link: http://matrixsynth.blogspot.com/2010/03/korg-polysix-keyboard-repair.html  Note the rubber contacts they are repainting.  You would essentially be doing the same job only it's applied to your emax buttons.  Same theory should apply.
