mini moog style synthesizer prototype project

"mini moog style synthesizer constellation like mini moog with an added percussion module on left side . its very well build prototype or was a tech project ? the percussion module on the side doesnt seem to do anything and the first 5 keys might be connected ? as intended . also the output is very low hence some background humming when you turn it up loud . the rest of the synth is working it definitely has a moog sound and seems to be very flexible .
reminds me of a sonic six have a listen to the audio examples. the synth is obviously sold as seen and might need a little bit more work but its totally special and worth the extra effort . sounds great like a real monster analog classic not sure how to price this could be worth lots so make some offers. oh pic is at an angle synths is perfectly even build"

Novation Bass Station (BassStation) Rack, Analog mono synth with CV in/out

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

via this auction

"It's got midi and CV IN control. AND it's got CV out, meaning you can use it as a 1 channel midi-to-CV converter too.

It's also got an external audio input so you can use its filter on other signal.

It's a beast, sounds great."

Sequential Circuits Six-Trak

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

via this auction

"Although typically understood as a slimmed down entry level offering from Sequential Circuits, the Six-Trak has the distinction of being one of the first multi-timbral MIDI synthesizers. Like the name says, the built in sequencer can access all six voices individually for easy stand alone composition.

This synth is in good working condition with typical wear for its age and nothing out of the ordinary, mostly just light scuffs on the panel."

Cwejman S1 MK2 Semi-Modular Analogue Synthesizer

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

via this auction

"This listing is for a Cwejman S1 MK2 Semi-Modular Analogue Synthesizer also compatible with eurorack format in mint condition. Includes original packaging.

The S1 is a semi-modular, analogue monophonic synthesizer. It is easy to get started with since it is prepatched for optimal use of its sound producing possibilities and eliminates the need for external connections between modules during use. Each module can be disconnected and used separately, e.g. to control or be controlled by other instruments. This flexibility enables and simplifies experimentation with creation and reproduction of sound.

We can mention some important features of the S1:
* Three oscillators with seven basic waveforms
* Ring modulator
* Noise generator with two three noise shapes
* Low pass filter with selectable 4 / 6 poles and quasi band pass mode
* Multi mode filter with selectable 2 to 6 poles and three modes
* Wide range envelope generators
* Master amplifier with build-in overdrive stage
* LFO with seven basic waveforms and wide rate range
* Extensive modulation of, virtually, all synthesis parameters
* Build-in MIDI to CV/gate converter with 16-bit resolution

Several parameters can be voltage controlled by external signals and, simultaneously, control external devices by the build-in MIDI converters voltage outputs (see Rear Panel). The S1 is a stand alone instrument and the possibility with patching and integrating it into an external modular (or semi-modular) synthesizer makes it extremely flexible..."

Black Baldwin IKE / E-MU EMAX 1 SE Plus Sampler w/ OLED Display SN 0690120

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

via this auction

"This Baldwin IKE has been fully transformed into an E-mu EMAX 1 SE Plus running the latest operating system (OS 1.0 Plus), which allows for hard drive support via SCSI!

Upgrades
Beautiful Blue OLED Display
Custom EMAX SE Overlay (contains all function/menu shortcuts)
Internal SCSI2SD Drive (4 "drives" on one SD card with 35 banks each; the first SCSI ID is fully loaded with a "best of" the Factory E-mu samples, the other 3 SCSI IDs are empty and ready for your creations!)
Loads entire banks in around 2 seconds
In addition to the SCSI2SD hard drive functionality, the 1.0 Plus Operating System contains all of the great/unique features of the EMAX SE Plus, including:

Spectrum Interpolation Synthesis: This provides a complete digital additive synthesizer. Up to 24 sine wave frequencies can be added to from Spectrums. These Spectrums can be placed at up to 24 time slice locations, so that the sound varies over time.

Transform Multiplication: TM synthesis imposes the harmonic characteristics of one sample upon a second sample to create a new sample.

This sampler is fully functional, and sounds like nothing else. I've listed it as Very Good for the following reasons:
There are a few cosmetic blemishes here and there, many of which I have captured via close-up image
The custom overlay fits perfectly, but the LEDs underneath are off center by about a millimeter; it is very minor, but worth noting
The bottom slider, which navigates through the menus, is slightly sensitive when at its lowest level/position; also very minor, but worth noting"

FREEMAN STRING SYMPHONIZER DEMO

Note: Auction links are affiliate links for which the site may be compensated.
Published on May 23, 2019 prosoloist

via this auction

"These are rare. Only a few hundred made I believe. Disputes in how much the engineer Ken Freeman would be paid I believe drove back production to where other competition hit the market first (the Solina and Crumar Stringman). But the Freeman has a unique place in that it uses 25 oscillators to produce a more vibrant sound than the other string machines
Freeman used low frequency oscillators (6 of them) patched to note groups not usually hit together. (diminished 5ths) The Freeman is big to house all the circuitry and they didn't exactly use the lightest materials.

The volume pedal DOES come with this one. The volume pedal is rather specific to this instrument. It has a feature that allows a 1/2 step bend to the pitch. It works fine. I never had the music stand.

Works great. No power cord, but you can use a regular electrical extension cord as long as it has an outlet on the top, not the side."
