"Built as a kit, it consists of 8 modules which could be connected with jumper cables to create an almost unlimited variety of different sounds. It has been stored for many years and with no way to test the unit (which requires an external amp and speakers) it is being sold for parts and repair.
Modules include:
Power Supply
Voltage Controlled Oscillator
Function Generator
Voltage Controlled Amplifier
Control Oscillator/Noise Generator
Voltage Controlled Filter – Band Pass
Voltage Controlled Filter – Low Pass
Keyboard Controller
Also included are booklets for assembly and operation of each module. Some of the booklets are stained but still readable. There are 6 single-wire and 4 coaxial jumper cables. The unit is about 32” long, 11.5” wide, and 6.5” high and is housed in a wood / metal case."
"The Pro-One is a classic. This one is minty fresh with MIDI. It also has a portamento knob above the mod wheels which you're not likely to see on another one. [Oberheim style knob]
This is the J-Wire keyboard version that's prefered by collectors and players.

"In this demo some eurorack sounds based on the VCA-AB.
One VCA-AB is used as a ring modulator. A pulse from the first VCO modulates the VCA. The sawtooth of the second VCO passes through the VCF. One ADSR controls the VCF and a second ADSR controls a second VCA."

"Virtual ANS is a software simulator of the unique Russian synthesizer ANS - photoelectronic musical instrument created by Evgeny Murzin from 1938 to 1958. The ANS made it possible to draw music in the form of a spectrogram (sonogram), without live instruments and performers. It was used by Stanislav Kreichi, Alfred Schnittke, Edward Artemiev and other Soviet composers in their experimental works. You can also hear the sound of the ANS in Andrei Tarkovsky's movies Solaris, The Mirror, Stalker.
The simulator extends the capabilities of the original instrument. Now it's a full-featured graphics editor where you can convert sound into an image, load and play pictures, draw microtonal/spectral music and create some unusual deep atmospheric sounds. This app is for everyone who loves experiments and is looking for something new.
Key features:
unlimited number of pure tone generators;
powerful sonogram editor - you can draw the spectrum and play it at the same time;
any sound (from a WAV file or a Microphone/Line-in) can be converted to image (sonogram) and vice versa;
support for MIDI devices;
polyphonic synth mode with MIDI mapping;
supported file formats: WAV, AIFF, PNG, JPEG, GIF;
supported sound systems: ASIO, DirectSound, MME, ALSA, OSS, JACK, Audiobus, IAA."
