i read yesterday that the practical difference between a DCO and a 'digital osc' 
is that the digital will always start with the same phase, and that analog, 
including DCO, are free-running. don't know to what extent this is true.
Well, that can be avoided by various methods that I can immediately think of.
the other issue with a digital osc used in unadulterated form is aliasing at 
high pitches,
Well, that depends upon how fast the digital oscillators are. Too slow, not good.

and for the filter,..so you are suggesting you would reproduce the existing 
filter, which is single across 8 voices, and offer a filter for each voice. like 
a 'proper' poly. question: is there a big difference between 'global' and 
individual filters?(if all are calibrated the same)
(what will be left of the original Poly ? ...!!!)
Yes, I think it's a big difference being that you get to hear consecutively played notes being affected by their own EG with their own filter. One filter limits the sound experience.I consider the single filter and the lack of independently variable waveforms to be Poly's major shortcomings on the sound generation side of things. HAWK gave Poly all of the MIDI control and extra modulations and stuff. But HAWK didn't do diddly squat for enhancing the sound experience of the Poly.
I figure, any new waveforms, modulations and filters are going to be a huge benefit to Poly. Yes, there isn't much left of Poly once we do this upgrade. But as with HAWK, if the external Poly looks exactly the same and the cost of doing of an upgrade is kept low enough, what's not to like?

    thought i'd mention: i'm messing around with MFB Synth Lite II and PolyLite 
synths at the moment. much lamenting online that the oscillators are not 
VCO, and not quite DCO - they are to be considered 'digital oscillators'...

point being: still an excellent (tiny) synth that does a great job of sounding 
like a large analog poly. it's filter and VCA are analog. 

the 1st edition elicited complaints, and he eventually revised the waveforms, 
which are generated by a cpu (these were made in 2003 and again in 2006, 
if that means much re: what was available then - and now). saw sounds 
pretty cool now. 

just saying that digital oscillator doesn't have to mean 'VA', and the thing can 
still sound juicy and analog. korg poly saw isn't exactly (isn't exactly a saw) 
a showstopper, so pretty much anything will sound good there :)

the other issue with a digital osc used in unadulterated form is aliasing at 
high pitches, and weird digi-artifacts (quite good when you find them on the 
MFB) - you can generate a saw that looks good in the midrange but if you 
want to avoid aliasing, you have to start limiting bandwidth as you go up 
in pitch (nyquist etc) - 

if you are thinking of using wavetables:are wavetables 'honest'(?) 
*in a DCO synthesizer?* 8-)  (hey, who cares, more waveforms to mess 
around with is good....could have squares and saws from a multitude of 
machines.

the MFB has ringmodulation and sync - apparently these are-necessarily- 
digital,  with whatever sound differences that implies (in practice, it's a 
machine that makes loads of good sounds,  has loads of variation, so it 
isn't an issue, for me,anyway) - so if you want to do crossmodulations of 
oscs, will that also be 'digital'?(worth worrying about?)

and for the filter,..so you are suggesting you would reproduce the existing 
filter, which is single across 6 voices, and offer a filter for each voice. like
