While the membranes aren't necessary if MIDI control can be utilized, I 
have a situation where most MIDI messages are not recognized by my 
Polaris, other than note on/off.
I commonly see the panels for the Moog Source for sale on eBay, but 
never for the Polaris. 
Given the number of units actually sold (or rather, the relative 
obscurity of this particular synth as opposed to anything that 
brandishes the Moog logo), let alone those experiencing the membrane 
death problem, it would probably be more along the lines of a labor of 
love for some very dedicated hobbyist, rather than a lucrative 
enterprise for a small company. 
Please allow for the possibility that I am, as usual, just talking out 
my ass :P
