Now of course, we should take a moment to consider some classic uses of the AKS/VCS3 - I'm going to combine them for the purposes of illustration - of course, we have Brian Eno - who can forget the sight of him live processing Andy McKay's sax while wearing some kind of ostrich feather jacket - (a point against the lab coat theory) . Pink Floyd's On The Run sequence - of course, which curiously is probably the most traditional synth sounding example.
A more recent example of processing would be the weird, sloppy filtering and ringing reverb processing of Alison Goldfrapp's voice on the track Deerstop from Felt Mountain.
Another seminal appearance is on Jean Michelle Jarre's Oxygene (and others), where it performed swooping ticking space effects (at least thats how I hear them).
You, like me might be sensing that the Synthi AKS isn't something you are going to reach for if 'fat analogue basses' is your thing, more the weird sound effects and subtle processing. But chances are, it's probably going be the coolest looking thing in your studio by some margin. Unless of course you're Jean Michelle. Jarre.
Current prices are hard to find as I can't find any trace of one being sold on eBay in recent times. Assume $$$$KKK and dream on.
