Yup the Arp 2600 and Korg MS20 are staples in synth history.

Which is one reason why I really went off the hinge when the truth about the KARP 2600's not-really-availability emerged. It, the MS-20, the Minimoog...ALL of these have what you'd call "performance practices" at this point, playing techniques specific to those individual synths, which means you'd be inclined to treat them as specific instruments and not merely "a synthesizer". I thought it was one of the most short-sighted decisions, and I still think how that was handled was a total botch-job. That's why, at this point in time, I'm NOT buying anything else by Korg. They're behaving weirdly...going from the zenith of the Odyssey, the MS-20 Mini, and the Volcas to this fiasco, the chronic issues that the Prologue had, reissuing the MS-20 in several Uli-esque colors for over twice the price of the still-available (and basically identical) Mini, and the retconned "improved" Minilogue XD, etc. That's not a good developmental arc.
