Roland SH-5 Vintage Analog Synth circa 1976

via this auction
"Features:
* Four oscillators in total: two analog, two digital
* Analog Oscillator waveshape are Sawtooth, Triangle, Saw-Triangle, and Pulse (with voltage-controlled analog Pulse-Width modulation)
* Digital Oscillators select from 96 wavetables from the Prophet-VS (128 x 12 bits), and 32 user-loadable (via MIDI) Wavetables (128 x 16 bits). The Digital Oscillators get trashy as the frequency gets higher, as with the original VS.
* Hard Sync on the analog oscillators
* FM and Ring Mod on the digital oscillators
* Separate Glide per oscillator, with two glide modes
* Real voltage-controlled analog lowpass filters - not digital recreations. 4-pole/2-pole switchable, fully resonant (in 4-pole mode). There are two separate filters, one for the left channel and one for the right.
* Analog Voltage Controlled Amplifiers (VCA), again one for each channel.
* Dual digital 4-pole Highpass filters (one per channel); place before or after analog electronics.
* Stereo audio inputs; Noise generator
* Envelope Follower and Peak Detect from External Input to use as modulation sources
* External Input can be used to gate envelopes and/or step the Sequencer
* Three snappy ADSR envelopes
* Four LFOs (sync with sequencer and MIDI)
* Dual (left and right channel) tunable feedback loops; modulate frequency and amount
* Delay with 3 taps; each with separate time and amount modulation. Syncs to sequencer/MIDI. Normal feedback and additional feedback path through analog filters
* Distortion! Digital, one for each channel, can be placed before or after analog electronics
* 3 Banks of 128 Programs for 384 total Programs - dump to/from MIDI
* 16 x 4 Analog-style sequencer - syncs with MIDI
* Extensive Modulation capabilities, including audio-range modulation. Bipolar (+/-) modulation."

Arduino Piano Squealer released under GPL V3

"Today I’m releasing the small monosynth, the “Arduino Piano Squealer”, I made for Critters & Guitari’s fantastic pocket piano. Examples and the code, released under GPL V3, are available from the APS’s own page."

Electro-Harmonix Vocoder, David Cockerell (EMS) 1979

via this VEMIA auction

"Rare and interesting vocoder, designed by EMS guru David Cockerell! Some sliders are a bit scratchy, but this is something you set up and leave, not tweak in real time - as the clever design with its recessed sliders and switches implies. Good cosmetic condition - a few superficial scratches, but generally nice, and, for EH product, VERY nice! Can be rack-mounted or is also free standing at a useful angle. Comes with a bad condition but readable copy manual. There is some insulating tape on the mains lead - a possible safety hazard that will need checking professionally. It is a long way down the cable, so there is easily enough to have that part of the lead cut off and the plug replaced. See a contemporary review at http://web.inter.nl.net/hcc/davies/vocbaeha.htm - and note that the price then was 428GBP - which equals about 1380GBP in today's money."

Synton Syrinx in purple (Titan) 1 of 8 !

via this VEMIA auction

"Extraordinarily rare version of this fantastic monosynth! Colour : Titan / purple only 8 were made of this colour. Voltage 230V. Virtually mint, so like new, no scratches or other marks except the tiniest marks at the edge of the panel above a keyboard B - see pic. Extras: clear hard plastic dustcover, and manual. Fully operational. Serial number is 01620OS. VEMIA note: one of the greatest-sounding monosynths ever, with filter sounds to die for - and in this ultra-rare finish!"

MXR 185 Drum Computer

via this VEMIA auction

"MXR's answer to the original Linn Drum. Twelve sounds: Kick, Snare, Rimshot, Clap, Block, CowBell, HiHat Closed, HiHat Open, Hi Tom, Mid Tom, Low Tom and Crash. Each sound has it's own slider (HiHats share one slider) with additional sliders for Click, Tempo and Pitch. Pitch allows you to change the replay clock speed for all the drums simultaneously, quite weird at the extremes. Individual outputs. Strange for a mid 80's machine is the omission of MIDI (there is an external clock / tape sync). Sounds are solid and very 1980's, Rimshot is different as it has a decent amount of snare. Buttons aren't velocity sensitive so there is an accent button used in combination with the drum buttons. Serviced, all buttons stripped and cleaned also with new backup battery, fully working. Condition is good, some nicks to the left hand wooden end cheek and a few marks on the front panel. Original manual included."

Analogue Systems TH48

via this VEMIA auction

"Analogue Systems TH48 Analogue Sequencer.Fabulous sequencer in mint condition. Hardly used. Has 3x16 step cv generators with optional triggering and individual outputs, random sequence function, internal clock with external CV input, external clock input, two chromatic quantisers with external cv transposition, slew generator for portamento and other effects, variable gate pulse duration with external CV input,conventional output + S-Trig for use with Moog synthesizers, the highest quality hardwware and design including copies of original ARP 2500 custom built knobs, Leds to indicate sequence position, clarity-simplicity and speed of use, 15 volt CV range. Comes with owner's manual, voltage can be switched between 220V-110V. Sequencer can be used worldwide without using a voltage converter. Sequencer is in mint condition."

Sequential Circuits Prophet VS Rack with extras

via this VEMIA auction

"If you want a VS Rack - and it's a fantastic synth, so you might well want one - you won't find a better example than this. Serial number 99, this one was restored by Wine Country in April 2002, and has been sparingly used since. It is in perfect working order, and has the latest operating system (1.2). It comes with the original manual in the classic Sequential folder; an unused RAM cartridge (originally an SCI RAM cartridge but adapted by Wine Country to RAM); a Wine Country Long Term Survival Kit (custom Voice Controller IC, front panel body & switch caps, front panel custom potentiometer, front panel knob*, data slider knob*, and footswitch jack); and a CEM3389 signal processor IC. Plus a certificate of restoration, with the embossed seal and Mr Sesnak's signature. (*Now no longer available at Wine Country!) This cost $2704 in 2002, which equates to about 1660GBP at the moment. Even if Wine Country haven't put their prices up in seven years (unlikely!), with shipping, insurance, and VAT / duty, it would be about 2150GBP."
