This is a demonstration of the Oberheim Two Voice vintage analog synthesizer!
Oberheim’s first synthesizer was a single-voice mini-module called a SEM (Synthesizer Expander Module). However, in 1975, Oberheim created their first compact, programmable and polyphonic synthesizer by coupling two SEM modules to a 37-note keyboard and a simple analog sequencer. This was what became the Two Voice. Oberheim achieved a polyphonic sound not yet seen in ARP and Moog gear at the time by hard-wiring the two monophonic SEMs into the compact keyboard design.
In 1976 Oberheim came out with another module, the Polyphonic Synthesizer Programmer. This could memorize the control voltages of many parameters for up to eight SEM modules. When these were added to the Two Voice, Oberheim finally had one of the earliest programmable and polyphonic instruments! Released alongside the Two Voice also came the Four Voice which had four SEMs installed, and a larger 49-note keyboard. And later, in 1977, a second tier was added above the four SEMs on the Four Voice to add yet another four SEMS, making the Eight Voice.
Two voices was great in 1975, and eight voices was pretty monstrous in the later seventies. But, a major drawback to these first Oberheim synths was that polyphony was achieved by having multiple modules. This meant that each voice had to be independently programmed. This also means that each voice has its own filter, making real-time filter sweeps of all your voices more than a handful! Fortunately the sequencer comes in handy for controlling each voice/module independently.
Despite its innovative features, the Two Voice was soon blown out of the water by the popular monophonic and truly polyphonic synths like the OSCar, ARP Odyssey and SH-101.
Multivox MX-65 Polyphonic Synthesizer. It is an analog poly keyboard that was made in Japan from 1977 to 1980. Very very rare.
It has six voices. Piano, strings, clavichord, honky-tonk, piano and organ. The voices them selves are just different combinations of the filter and envelope positions that you can switch between. The filter is interfaced with the envelope with 3 modes. A fast attack/fast decay mode, an ‘expand’ mode with resonance emphasis, and a fast attack/slow decay mode..
Excuse the poor playing! I am trying to focus on the controls and just show a quick demo of the sound. Reverb in Ableton.

About RSF and the Kobol line:
The RSF Kobol was the French synth company’s first compact keyboard synthesizer, certainly inspired by the Minimoog. It is a much more compact instrument than the Modular Model 11 series of synthesizers they had been making thus far. It is a monophonic analog synthesizer with traditional controls, knobs, switches and two oscillators for a good solid analog synth sound. Initally released as a keyboard in 1978, a 3-unit rack-mount system was later released in 1979.
Although it is mostly a traditional analog synth with stable oscillators and lots of knobs that allow you to control the ADS envelope, the filter section and the nice LFO, it did offer some unique features for its time. Most notably, the oscillator waveforms can be continuously swept across for a very cool morph from square to saw to pulse, etc. This, as well as note on/off and other parameters can be controlled via CV/gate. External sounds can be processed through the Kobol filter and envelope sections too.
The rack version came in four different components. The Kobol Rack (Expander I) was essentially only the VCO/VCF/VCA/LFO sections of the Kobol in a rack module. The Expander 2 was an add-on to the Kobol that added some new processing modules such as ring modulation, sample-hold, and envelope followers as well as extra VCA and LFO modules. The Programmer rack module contained the memory circuits for storing patches and sequencing. And the KM8 was an 8-channel rack-mount mixer. The connections between modules were normalized but could be bypassed by external patches, similar to other semi-modulars like the ARP 2600 and Korg MS-20.
The Kobol looked and sounded great, and was quickly snapped up by the big names in synthesizers of the time. But being a small French company, RSF were never able to truly mass produce these on the same sort of scale that Moog, Arp, Roland or Korg could. Less than 200 Kobol keyboards were made, around 800 Kobol Racks, 200 Expander 2′s, 200 Programmer’s and only a handful of the KM8′s. This makes them quite rare and quite pricey too!
PollySynth, a ‘multiplayer polyphonic synth’ that combines elements of gaming with synthesis, is now available as a public beta. It is designed for browser-based use with mobile devices.
Synthesizer voices are visualized as members of the ‘PollySynth gang’. Players fly these characters around and create audio havoc by loading a website on their mobile and playing with the controls. Spatial audio effects add to the fun as characters zoom by.

All sounds from the 1978 Roland Jupiter-4 analog synthesizer. One of the best sounding analog poly synths ever built.
The first Jupiter synth. It was among one of the first poly synthesizers (4 individual voices which could be synced together for one fat monophonic lead), it had a pitch wheel that could be assigned to the VCA, VCF, VCO or all together, there are 8 memory locations and a cool arpeggiator – the arpeggiator can be heard in the Duran Duran classic, “Rio”. It also has a very slow LFO for those ever-so-long filter sweeps. Pretty good for 1978!
Not so cool however, are the 10 preset sounds which sound nothing like the piano, brass or strings they claim to be. The placement of all the preset buttons below the keyboard can be inconvenient, especially while playing it. And as with most old analog synths, the Jupiter-4′s tuning can go out often. Still it is a nice analog synth for creating weird trippy analog sounds.
Honestly not sure if this is something we’ll ever ‘stock’ or be able to sell you, but it was too cool not to post! The second part of this video features direct stereo sound in from the 8 Voice.
ReDominator is an emulation of the classic Alpha Juno 1/2 (JU-1/2), a polyphonic DCO (digitally controlled oscillator) based synth from 1986. The JU-1/2 became popular in the early 90′s techno and rave scene particularly by the classic Hoover sound (which ReDominator attempts to emulate accurately). But beyond those niche sounds there lays a versatile synthesizer that does bass, pads, leads, organs and a lot of other sounds waiting to be discovered!

Soundtrack composed 100% with Prophet 12!
Introducing the Prophet 12 Module, the same great sound engine of the Prophet 12 keyboard with enough portability to fit in a backpack! At twelve voices, the Prophet 12 boasts the greatest polyphony of any instrument designed by Dave Smith. Each voice features four oscillators capable of generating classic and complex waveforms, a sub-oscillator, resonant analog low-pass and high-pass filters, and analog VCAs. The new Character section adds a variety of wave shaping and sound sculpting options, like Drive, Hack, Decimation, Girth, and Air. Additional features include a tuned feedback path, a four-tap stereo delay per voice, expanded arpeggiator functionality, deep modulation capabilities, and bi-timbral operation. The LFOs, delay, and arpeggiator can all be synced, either to the internal clock or an external MIDI clock.
