via this auction

"Vintage MOOG Opus 3 analog synthesizer in Excellent Condition. Serial Number: 5828 Made in Buffalo, NY, USA. This is the legendary polyphonic sound design from Bob Moog which produces strings, brass and organ voices individually or in any combination, plus layered effects combined with full stereo panning."

Roland Jupiter-8

via this auction
"As its name suggests, the Jupiter-8 is an 8-voice polyphonic analog synthesizer. Each voice features two VCOs with cross-modulation and sync, pulse-width modulation, a non-resonant high-pass filter, a resonant Low-pass filter with 2-pole (12 dB/octave) and 4-pole (24 dB/octave) settings, an LFO with variable waveforms and routings, and two envelope generators (one invertible).

Noteworthy performance features include adjustable portamento, a hold function for making sound design easier, a versatile arpeggiator with DIN-sync and external analog clock input connectivity, assignable pitch-bender, instrument layer and split modes, robust load and save functionality for its 64-patch memory, built-in XLR outputs, and—in addition to legato and polyphonic modes—the Jupiter-8 includes a powerful unison mode.

A Z80 CPU was used for managing storage of patches, scanning the keyboard, display, and buttons, port handling, and taking care of the auto-tune function among other things. The VCOs were discrete. The VCF was based on the Roland IR3109 IC (also used in the Jupiter 6, MKS-80 rev 4, Juno 6/60, JX-3p respective filter circuits). The VCA was the BA662. The envelopes were hardware generated by the Roland IR3R01 chip (also in the Juno 6/60), and are much faster than software generated ones in the subsequently introduced Jupiter-6 and MKS-80 "Super Jupiter"."

Envelope to zero 4. Cross-modulation (filter cuttoff is modulated by VCO...nice trills)

All of the mods have a bypass switch and a status LED. The cross modulation also has waveform selector and amount control."

SEQUENTIAL CIRCUITS PROPHET 2002 PLUS

via this auction
"The Prophet 2002 plus is a rack-mount version of Sequential Circuit's Prophet 2000 Keyboard Synth. It has an Arpeggiator, Curtis analog VCF and VCA and an incredible raw 12 bit sound. The 2000/2002 Plus versions had a little bit more memory and 8 outputs instead of 2.

Its not only a sampler but also a synthesizer, its got 16 built in digital waveforms which can be used as oscillators to go through the filters and VCA. A very distant cousin of the Sequential Circuits Prophet VS."
