I've got spare keys for the chroma polaris if anyone is interested.

Also, I recently replaced the now obselete DAC on my polaris with a 
handwired socket adapter using an Analog Devices AN7538 DAC.  I can 
provide the adapter + IC to anyone who needs them or email 
instructions.

2 more thoughts (mods that I haven't done yet, but should work-- not 
sure when I'll get around to implementing them):
To expand the 8 position resonance control, it should be possible to 
install socket adapters to the CEM3372 chips and add a pot to the 
resonance input.   This would give real analog control of that 
function (but it would not be saved w/the patch).

The same sort of minimally invasive mod could be done to provide OSC 
level controls and over-ride the muting of OSC2 when Ring is engaged.

I think that the 3 pots could be installed above the pitch and mod 
levers.

I hope this saves some instruments.   Now that my polaris is 
functioning again, I look forward to some playing time.
