Korg X-911 Analog Guitar Synthesizer

via this auction

"the Korg X-911 is a rather versatile effect processor as you can process any signal (guitar, microphone, sine wave, etc) to get a unique sound by layering the onboard instrument sounds with the onboard "Synthe." This unit tracks best with single notes, though it can do some interesting unpredictable things if you send more than single notes. The buttons look like the panel from a Polysix, but the filters inside are closer to a MS-20/MS-10 type synth."

1979 Yamaha CS15

via this auction
"This is a great duophonic synthesiser, with two almost completely independant synths in one. 2 Oscs (True VCOs), 2 multi mode filters, 2 Envelopes and 1 LFO (with Sample & Hold!!). It gives you 2 independant signal paths that meet at the outputs (hence duophonic). It has all the usual waveforms and an external input so you can feed your drum machines, computer, records or even your voice through one of its multimode, highly resonant filters and VCA. Filters have Low Pass, Band Pass and High Pass settings and can be tuned independantly. The envelopes have two modes normal (which makes them pretty snappy) or 5 times which slows the rates to 5 times slower, making it ideal for drones and effects. One of the envelopes can even be set to trigger in response to audio presented at the external input, allowing for envelope following like effects to be applied to the filters and/or VCAs. Feed it a drum loop and you'll see what I mean. On the back there are CV and Gate inputs and outputs for interfacing with the rest of your gear (I have tested the gates and they work as expected, I've never tested the CV connections but have no reason to doubt them). It has two audio outputs (1 high gain and 1 low), feeding the high gain back to the input allows for extreme feedback effects."

Roland SH09

via this auction

"A monosynth from Roland's classic SH-series. Its single oscillator has PWM, ramp, square and noise waveforms. It has a similar architecture to the SH-101, the VCA can switch between gate or envelope, the VCF is pretty standard, and there is a sample-hold function which is great for VCF filtering into acid and back! Another cool feature is its external input which will allow you to filter external audio through its VCF."
