Dave Smith Instruments SYNTHESIZERS

Hello all,
I have had an evolver since I first heard about them (ser # 00638), So I've had it a while and totally love the sounds it makes. I am considering selling some gear I don't use much to get a Poly Evolver, but so far I have not heard anything that impresses me enough to make it happen.

Can somebody give me a compelling reason why I need a poly? I just haven't heard any compositions that I could tell were that much different than the single evolver.

Thanks
