I have only heard of 3 or 4 synths that have the Vector Synthesis architecture and joystick, and let's face it: how much would I have to pay for that Prophet VS, and what condition is it in?

The blend of FM and AWM(sample-playback synthesis) is one hell of a unique combination that is nearly unbeatable(in this price range) for strings, pads, EPs, weird sounds, and even some organs. The pianos are remarkably good for a synth made in the early 90s, and the analog-esque sounds are decent IF you don't try to use them in dance/techno/house music or your Rush Cover band since the SY-35 has no filters.

However, the SY-35 does have its place in rock and metal - especially since it's thin sound sits extremely well(much like the DX-7...) in a mix with walls of guitar, bass, and drums. This synth also accepts rom/ram cards and has a nice feature many synth makers overlook(Yamaha itself even omitted this from the CS6X!!!): the ability to hold out the notes and switch voices, with the new sound not being heard until a new note is pressed - a great(!) feature for playing live if that's what you do.

Keyboardist Elizabeth the Muse, of Khasm(www.khasm.org) has used the SY-35 almost exclusively over the past 3-4 years of her tenure with the band to help create the atmospheric/gothic/doom vibe Khasm is well-known for, and if you listen to the band's song "Mother", you can really hear the SY-35 in a variety of contexts.

I have to say that, given the situation of only having one synth to play I would glady choose the SY-35 over the Wavestation, SY77, or even the M1 for its unique features and sound architecture. I could live with the limited polyphony, simply because the quality of the sounds are quite good. This synth sold for $750.00 US new, and can be had for less than half that amount - IF you can find one in good condition, jump on it.....not literally, of course. :)
