there is no software that even comes close.
im sure there is software that is even better, in fact im sure of it, but no software can sound like the hardware. and probably vice versa. or not, i dont know.
the thing about the emu is you may wonder how the hell ed rush and optical did their warpy bass or how neuro leads work in general but with the emu its hard not to make neuro leads, if you just sit down with it, sample some crap and let your mind wander as you fiddle away with that little green screen and the dial and the calculator keypad you will wind up with a neuro warp. again, not claiming what i make is any good, or that there isnt better stuff out there, its just thats how the emu sampler works. this post is based on a quote by pyro btw, he said it on doa many years back, its just really true, so i often say it when this discussion pops up
