So many vintage synths now have upgrade options like the Europa mod for the Roland Jupiter 6, the KiwiTechnics JX-3P, The Tom Virostek DSS-1 upgrade, the Johannes Hausensteiner and KiwiTechnics Polysix upgrades, the MIDIpolis IO (JP4), Minerva (Ju60) and MidiPoly (Mono/Poly) upgrades, etc., etc. I understand that many of these are primarily viewed as MIDI upgrades, but most come with the benefit of new added features at the same time. I have the JP4 IO (more patch banks AND two more LFO's to VCO and VCF with selectable trigger modes!!!), the Jupiter 6 Europa which gives you a gazzilion new features besides the upgraded MIDI specs, and the Johannes Hausensteiner PolySix MIDI upgrade that comes with added patch memory, in depth voice assignment, a noise generator, and the ability to mix the saw and pulse simultaneously . . . all are awesome. 

Tweakable voice assignment is one of the things I'd love to have on the Polaris, and another LFO or two . . . along with things like Patch Edit Compare, a simple Save/Dump all patches, and - I know we're probably getting into added hardware territory here - individual OSC volume mixing. 

So I'm curious if anyone has ever talked about or considered doing this . . . and also what other features fellow Polaris owners would put on their wish-lists if such a thing were to happen? 

Cheers,

James
