Dave Smith Instruments SYNTHESIZERS

I am really considering buying a desktop evolver or a poly evolver rack but I had a few 
questions first.  I have too many analog or VA synths already(prophet 5, Nord Modular, 
Juno, JX3-P, OB Matrix6) so I'm not looking for another analog, not really my reason for 
looking at the evolver.  But I do need something to replace a long since dead prophet vs.  
I'm wondering how the digital pads sound on the desktop or poly evolver?  I know they 
have the same wavetables as the vs, and I know they are not vector like the vs but I'm 
wondering if anybody has managed to create any decent atmospheric pads similiar to what 
the VS was capable of?  I only had a chance once very, very briefly to try out a poly evolver 
and what I heard sounded good, but it seemed the presets I heard were more analog than 
digital and also they all seemed to be sequences.  All the samples I have downloaded from 
the net seem to be either more analog stuff or really harsh and noisy stuff.  Also I'm not 
sure how limiting it is being 4 voices, I know on my prophet I do quite often run out of 
voices.  Anyway just curious to see what people think.

Oh yeah, how is the unit with external sysex controllers.....is there any aliasing or delays 
when controlling them??  I know on my OB the filter aliases as well as skips about when I 
move the knobs on my sysex controller too fast, and live control is a big issue for me.
