I was finally able to go buy a VA synth without having to worry too about multitimbrality, polyphony, etc. The rest of my setup allowed such a purchase. So, when I went to buy the Nord2 or MS2000 or Nova, I ran into the XT.
I had an AN1X briefly last year - pain in the ass to get around, limited knobs, it did sound good. And the JP8000 never did sound very analogue to me (very digital filters). Haven't been able to try a Virus.
After auditioning the nord, korg, nova, Q and yes the JP again for over 2 hours, I kept going back to the XT. Not analogue, but overall, the best sounding of the bunch. It does everything from warm strings and 'analogue' bass to PPG bells and nasty industrial noise (think Front 242). I never thought a synth could sound so meaty. I have read complaints about the bass, not the best but very usable. Haven't gotten too deep with it yet - basically just finding reasonable patches, tweaking and sampling. I bought the XTK because of the construction quality. Couldn't get over how solid it is. Built like a Mercedes, as if it were chiseled out of a solid piece of granite...Next will be the microQ - Waldorf means techno heaven.
