I'm starting to suspect that the world doesn't hinge on which synths I buy, keep or re-sell, but...
After only having a second System 8 for a few weeks, I've sold it. I really do dig that machine. We all agree that the System 8's own engine is worth its weight. When I was prepping to sell, I programmed a handful of patches to show off the range of the S8 engine. That alone almost stopped me from wanting to sell. I had a freako-mechanical thing next to an industrial unpleasantry followed by a gentle FM bell followed by a Juno pad... the System 8 is very versatile.
I think though, that the pull of the "almost unknowable" keeps hitting me. Not that I'd mastered the S8, but to be able to program a range as broad as I did in ten minutes certainly shows how comfortable I'd become with the synth. My downstairs studio isn't synth-heavy. I had the S8, the Trigon and the Taiga. The latter two were the ones that kept pulling at me. They have a mystery to them that I can't deny. But they also feel and sound more like "me, now" than the "Oh, I remember this!" vibe that the plug-outs were giving me on the Roland. Not that I don't adore the classic sounds, but as I've probably said before, those sounds are "ours," not "mine."
Long story short, I have an ARP 2600m on the way! I'm hoping it will pair weirdly with the Taiga. I've only used a 2600 once in the wild... at the end of a studio session, we plugged it in and came up with a suitably WTF fuck tone.
I have so many "straight" synths and I don't lack for classic strings, brass, pads, leads etc. Here's hoping the 2600 freaks me out like I suspect it might!
