Tech tips

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. -Ben
