On the chips issue, part of the sound comes from their environnement, the Kobol sound a lot better than the other using the same chips (dont remember on the spot, getting old… sigh).
The trouble with the evolver is the hybrid part is not advertised properly in demo. A friend of mine in toulouse just stumbled on it after thinking bad of it for months… It's easy to make strange sounds in the digital part (wavetables) so the demoist tends to overlook the 2 analogue VCOs and the filters. NOW, it's not a FAT synth. and it's not the most unstable (he can't) and lively around.
From what you say, you seem way more interested into some fatness and instability, the organic part of analogue. In VA, look at ION/MICRON. In real analogue, it's the Voyager, Studio electronics and Macbeth your friends.
I've answered elsewhere on the ATC stuff. the only point I can add, ATC can sound more analogue, they ARE analogue!
The SE-1 is a fat bastard (sorry folks), but it's really a Bass synth IMHO from what i've seen/heard. ATC is more versatile. The SE-1 is the Mini of Studio Electronics, don't confuse with Roland and its DCOs, SE-1 have VCOs. i've only heard SE-1x so can't tell on the filter stepping.
Historicaly Studio Electronics did
- MIDImoog
were real Minimoog model D midified and racked
- MIDImini
were Mini recreation in rack form
- SE-1/ATC-1 are the next step
I've never met the Omega8 it's a rare beast so… can't tell.
Envelopes… it's not the speed of enveloppes which makes the sound in fact but the slope shape. You can have the fastest enveloppe in the world (digital that is) it just won't sound fast the right way, they had the problem on the Andromeda wand they added a sloppy mode which makes wonders in moogish sounds. Now in analogue, the fastest envelopes around are in Technosaurus Selector systems (about 3 times faster than minimoogs) but the synth doesn't need them to be analogue up to the tip of its nails (of saurus
I think it's very dangerous you want to find the sound of old gear in new gear, it just can't be done. We don't have the components anymore to build them that way or it'd be just economically a furious thing. So for "old sound" go legacy synths. For analogue, it's nirvana now, there's never been as much companies building them and as much hardware available. but from what you say, I think you should either go in VA to Alesis, but the more obvious given you background (and safest) and the hints of sound you seem to look after, would be to go to Studio Electronics and at least ATC-1x.
Novation are just spitting wave sample synth out, sounding s***e IMHO
I LOVE alesis, even their QS family
f… up to program but sounding sweet, their VA ROCK.
Waldorf is dead, and almost no more analogue. The last real monsters were the microwave 1 (analogue filter) and The Wave (a beast). i wasn't crazy at the Q+ (but the analogue filter did really the trick though). The demise of waldorf is really something bad for synthesis.
On clavia, "grow up", get a NM G2
you talk about the Leads and the old ones in fact. Also Clavia has never been running after the Moog fat effect. Analogue is not only that.
You forgot vermona, but it's cold dark analogue, sounding very german/elektro, I like them a lot but it's not for you.
One last you forgot is Macbeth. Ken makes really great synths, he did one of the best mini-like synth around the M3X (only second hand now) and now he builds the M5, a monster über half-modular.
