Zampler-RX is working via LinVst, it's another sfz host,
coded by Synapse Audio, has envelopes for amp, mod, and filters,
3 lfo's, and a nice effects section. There is a 170 meg demo soundbank,
and 3 free sound collections at the link. Zampler-RX is a 2.3 meg download.
The gui is attractive and works fine.
