Waldorf Microwave XT hands-down! 43+ knobs and always have missing time from my life whilst donning headphones and tweaking knobs. It does not only have massive wavetables but ring mod/FM/and your regular wavefoms and really great array of digital filters...it can blow out speakers easily if not careful.
The second is the aforementioned DSI Evolver Desktop, which can run it through ext in of XT or the XT through the Evolver and that's ALOT of twiddling not to mention you talk to aliens!

After this past few weeks with Waldorf Q rack (obtainable used but do not come up that often), can safely say very tweakable on the surface, with a mod matrix reaching heaven or hell--it can go both ways as far as sounding, well...what the Microwave XT cannot do, the Q can! Would not surprise me to see on an alien spacecraft, both the orange XT and bright yellow Q occupying 10 rack spaces as their form of intergalactic radio!!:D Maybe there IS something to the term "Waldorfians"...those Germans are aliens under the store front of a synth company!
Honestly, I dare say this gives the Virus a shakedown!:twisted: Yes, it's bright yellow but no dino!
