Simmons SDS 9 Synth Drum Kit -- 5 Yellow Pads + MIDI Brain

via this auction

"vintage, working Simmons SDS 9 Drum Kit, with brain, four tom pads, and piston-loaded bass drum pad (with spurs), and a print-out of the manual (that you can also find online)...

My favorite part of the feature-laden SDS 9? That's hard to say. You can trigger any of the brain's 40 kits (20 factory set, 20 user-programmed) by MIDI, or by sequencer, or by the iconic hexagonal pads (in the coveted yellow color); you can play around with all sorts of ADSR/tuning parameters on the individual channels, then save your drum kit settings onto a Data Cassette! (I've included a sealed, unopened maxell cs-500 hd data cassette in this auction for the lucky winner); there's a built-in, fully programmable delay feature, 1985-style, that's not found in other SDS brains; there are individual outs for all of the channels, and you can replace the snare and rim shot EPROMs with whatever other Simmons EPROMs you can win here on the 'bay... and all that's very cool... but to me, perhaps the coolest part of the SDS 9 is the fact that it combines 3 types of vintage synth-drum sounds into one kit... the gritty "computer generated" sounds of the bass drum, the analog circuitry of the earlier brains for the three toms, and the EPROM early-sampling technology for the snare and the rim shot."

YAMAHA SK-20 analog string/brass/organ synth

via this auction
abertronix (RSS)

"A lovely sounding organ / strings / polysynth . String sound is comparable to the Roland RS 202 and you can build up more complex sounds because of the 3 sections. PItch of the organ/string section can be detuned against the pitch of the polysynth. It contains an excellent ensemble effect in addition to vibrato and tremelo effect. Its a little heavy so best suited for studio use! The analog section strings/polysynth sound , to me , is very beautiful ; grainy ., a very physical real sound."
