Wavetable (read sampletable) is great if you want to do a 
mulit-timbral LA/AI thing like the ESQ/M1 ,but IMO vcos are it! 
The basic mixed waves from two or three vcos produce some strange 
results, usually much more complex than I expected. Always rich 
and full of harmonics.

For example if you only had $100 bucks and you found a 
Prophet 5 and a ESQ each priced $100. Which would you buy?
(They both work great)

The best sounds are a little loose and flakie. - MO

You'll never sell me on aliasing being a feature! - Also MO

You could look at the VCO-2D and VCO-4B in the Maxx2 as mutated 
Taurus vcos. It's the same basic design shuffled arround a bit.
I guess you could by this logic look at the Maxx2 as a mutated
Taurus....It's got the vcos and filter...:-)

I have built a quite a few of those Taurus filters. Transistor
matching doesn't seem to matter much as long as you use a 3046
for the top and bottom pair. The 3080 is a much better solution
than anything else I've tried. DC coupling sounds better to me?
Can't explain it, it just is....Well the best cap is still.... 
no cap.
