Actually, yes. That's what I use it mostly for nowadays. I can do some good lead sounds too.
Just remember that in the poly the filter is monophonic eventhough it's an 8 voice synth. You can setup in two modes, either the envelope retriggers if you press another note while holding one, or the filter doesn't come on at all. Depending on what you're playing this may be give you a funny effect.
I wish I had a jupiter 8 because that's the ultimate killer filter sweeps synth. :-)
