Which are the current analogs to get that S. Winwood sound..

I am trying to find that perfect synth that will give me the sweet crunchy low dark sound in "Don't You Know What the Night Can Do", the "Valerie" solo and accompaniment as well as the synth in "Finer Things", basically want a synth that will accompany music like Winwood's 80s material.

Any of these?

Andromeda

Prophet '08

Poly Evolver

Yes

For the lead sound on the original Valerie and While You See A Chance, Steve used a Minimoog. Later, this sound was replicated on Finer Things and the Valerie Remake (Greatest Hits) using a Yamaha DX7.

String sounds on the earlier albums were done using the Prophet 5. In fact, the entire Arc Of A Diver record is filled with Prophet 5 presets.

So, to answer your question, if you want an analog synth, any of the ones you listed, should be able to provide you with these sounds.

It's a couple of sawtooth waves in close tuning so that they phase, a static filter mostly open, a slightly slow attack, and appropriate saxaphone phrasing and pitch bending.

Go ye therefore forth and program it on whatever is at hand.

Actually, it was a Multimoog.

But, you should be able to get that sound on any 2-oscillator analog.

He also uses that great lead sound on George Harrison's "Love Comes to Everyone". The key is that saxophone phrasing using the pitch bend wheel (which I'm absolutely hopeless at doing well).
