Thanks for the solid feedback!
My reasons for selling the System 8 were... vague! I think I like having various bits of gear that I can imagine letting go of. You know, in contrast to, say, the Prophet 5. I'll be buried with that thing! For the most part, allllllll the synths I now have are keepers. They're instruments I truly love and am thrilled to play every time I use them. The System 8, because of its plastic plastic-ness and its gaudy green lighting scheme felt, at least at first, like an "Are you kidding me???" joke. Obviously it ain't - it's a far heavier machine than I'd assumed.
It's not that I loved the S8 engine with all my heart, but rather, the oddball options it offered were in contrast to most everything else I owned. The only other synth I have with a digital anything inside is the Prologue. I ended up with a DX-7 for the second time in my life a few years ago, but the novelty of that wore off quick and I sold it. The S8, though, can move into all kinds of territory. A really wide range of "HUH?" sonics. And as with my other gear, once I'd got the hang of where it could go, I knew when to reach for it. It could give me certain clean-and-dirty-at-the-same-time sounds.
But the System 8, besides the sound, is all about features and functions - and fun! I used to sync it up to the Roland TR-8S and suddenly it's Acid House Revival. I was never even into that stuff in the first place, but finding out how much groove the Roland team could generate, I became the lonely king of the basement dance party! So, yeah... the System 8 really won me over, over and again.
Those are reasons I might want another one, and reasons why I didn't want to let mine go. The main reason for selling it, though, was to raise money for the Taiga. If the S8 seemed mysterious, the Taiga seemed doubly so. The Taiga is still mysterious, but the System 8 keeps phoning me up at 4am asking if I wanna go out sometime! I found one today for $1250. "Thankfully," the seller told me he had a pending sale and had forgotten to mention that in his post. So, despite the general price hike, the S8 does pop up for around what I paid for mine a couple years ago.
Oh, we'll see where this leads! Thanks also for your quick glance takes on the Hydra and Bree6. I'm quite happy to be talked out of anything at the moment!
