a very nice free chorus
the good folks who emulate all the guitar pedals did this rack chorus plugin.... I haven't used it extensively but its pretty fully featured and has a retro, colored sound that's more early digital than analog to me.... think dimension D maybe? but with adjustable aprameters. Very ncie chorus when you need tweakability. I would sue this on a guitar track or a synth or anything really, maybe even a vocal. Nice. I gotta find a song that needs it though.
