Yamaha SY-2 SN 2984 with CV/Gate/VCF mod

via this auction

"This is often called a "Preset" synth, but that is deceiving as pretty much every function (Filter, Envelope, etc) can be overridden and set however you want. It shares the same gnarly diode-based dual VCF (and a lot more, I think) with the legendary mega-expensive GX-1 solo synth section and has Highpass and Lowpass filters, both with resonance. It also has the smoothest, most expressive optical aftertouch I've ever used. This is really one of the best sounding monosynths I've ever heard, and also one of the most characteristic. I'm probably crazy for getting rid of it but am desperate for some cash to fund other projects.

Cosmetically it's in nice, very clean condition with some minor scuffs and wear. One switch shaft (Vibrato Preset/Control) is slightly bent askew but functions 100% properly. The lid is missing one clasp and some of the tolex is starting to come unglued from the lid trim.
Functionally it's perfect, everything works as it should and the CV/Gate mod allows it to be played from a midi-CV converter or analog sequencer. I'm not too into acid, but the filter architecture on this makes it a really unique acid machine when sequenced."

Note: links to listings are affiliate links for which the site may be compensated.

via this auction

"Synsonics Drum Machine (Model 5450) with Box and Accessories. This Synsonics "Drums" drum machine/synthesizer is in excellent working order and very clean (seems to have been never used). This machine was marketed as a toy, but can produce some really cool sounds with the tone wheel and other features, and has the audio outputs of a upper-level drum machines (1/4 in. headphone jack, stereo jacks, ACC jack, and input for a 9 volt DC power source -- was not originally included, nor included in auction) plus on-board speakers. Comes complete with original stereo cables, users manual, and Synsonic brand drumsticks. Original box with flip open window is included, but has some wear (creases, window is slightly loose, etc). This item, especially this model, is very hard to find with everything here, would be awesome for any collector of 80's/90's toys, but also an amazing instrument for any musician making new but rarely heard vintage beats..."

via this auction

"A solid & practical metal box. The spacey decals are a tough vinyl.
The base of the unit screws on with 6 screws & if powered by mains is ideally left in place. If you want to power it with a 9v battery, the base can be left off for easy access to change the battery. See the image of the internals from underneath. The base has felt pads on for a soft seating.

A brief explanation of controls etc.. The front panel pots from left to right....1. Sensitivity, adjusts the sensitivity of the trigger pad & determines how hard it needs to be struck.
2. Decay, Sets the length of the phrase/note, from a short sound to a long decaying sound.
3. Sweep, you can sweep the pitch if the vco for hands on effect.
4. Rate, The frequency of the modulation.
5. Mode, The shape of the vco.
6. Nz/Pan, Adjusts the amount of noise to be mixed with the output signal. (Linked to a switch on the rear of the
unit to select noise colour)
7. Level , The volume knob.

The rear panel from left to right.... 1. C.V in, control voltage in, 2. noize tone switch , 3. trigger input , 4. On/Off switch , 5. 1/4" jack output, 6. 9v dc power input."

Hackme Rockit Synthesizer

Note: links to listings are affiliate links for which the site may be compensated.

via this auction

"This is a handmade Rockit synthesizer designed by Hackme Electronics and built from their circuit board. It is a monophonic digital-analogue hybrid using two 8 bit VCO's through a digitally controlled analogue filter and VCA (with 2 LFO's thrown in for good measure). All parameters are directly controllable on panel (and via midi cc). It is powered by 6 x AA batteries (rechargeables are fine). It weighs 1.8kg.

http://hackmeopen.com/rockit-build-info/

Rather than use the standard Rockit case, I have housed the synth in a wooden box with brass front panel. All controls are securely attached to the panel rather than PCB mounted. Leaded solder was used throughout.

The controls are:

Back row
Drone switch, volume, on/off, midi-in, midi-thru, audio-in (to use filter and VCA), audio-out

Left block of controls (from back to front)
VCO1 waveform, VCO2 waveform, VCO mix, VCO2 pitch
A, D, S, R for VCA
Filter cutoff, filter resonance, filter ADSR depth, low/band/high pass filter selector
A, D, S, R for filter

Right block of controls
LFO routing matrix
LFO waveform, LFO rate, LFO amount, LFO sync

And at bottom are the patch save/recall controls..."

Magic Ceramic Theremin Lamp Doepfer A-178

Uploaded on Nov 22, 2011 creativegallerysynth·19 videos

"The first test of the Magic Ceramic Theremin lamp. It is developed as a peculiar piece for the opening of the Exibition of several ceramists in Gallery Artibrak. from november until 28th of December 2011.
A theremin is normally stepless, but in this case an A-156 is used as a quantizer..

Small explanation for those who are not familiar:
In this magic piece of ceramic two antenna's are integrated. One antenna for the volume and one for the pitch. The instrument does not have to be touched. The volume can be controlled by your left hand (when approaching it the volume increases), the pitch can be controlled by your right hand (when approaching it, the pitch of the sound goes up). By approaching the antenna's you are influencing the potential difference. Just like the antenna of your transistor radio which functions well or not when approaching it.

The Magic Ceramic is based on the original Theremin invented by Léon Theremin in 1919. That electronic instrument is stepless variable and very expressive. It sounds like an opera voice or violin.

This ceramic version of the instrument has a much more variety than it's original. You can make the sound stepless or let it be quantized, so that you hear a real tonescale/musical scale. The sinus-tone of the Magic Ceramic is quantized (chopped in pieces), and in the way it is presented now only the Minor notes are heard. (like the black keys on a piano) In this way the steps between the notes are bigger and easier to distinguish. Other possibilities are just Major notes or the complete tonescale, quantized or not. There is also a small sampler added, so when you reach the highest note a spoken voice can be heard.
