Ouroboros Tube VCO Demo - Mark Steiner


video upload by Mark Steiner

"Some of this shows the sound as is with just a sequencer changing pitch. Much of it also then shows the sound with a VCO modulating, mainly at audio rates. Fun stuff! Long, but just how I'd want such a demo if I were thinking of getting one.

This module is no longer made but Ortho is working on another Tube VCO currently."

Ouroboros Alea Taction • Semi-Modular Analog Touch Synthesizer


video upload by Ouroboros Electronics

Pre-order at Nightlife Electronics. US distribution coming soon.

"Alea Taction is a new iteration of the classic Alea with the addition touch plates as well as a new aesthetic and enclosure. The touch plates open up another another dimension of gestural control and influence which the user has over the instrument - providing more potential for variation and playability within a patch, and a deeper, closer connection and involvement with the instrument. The touch plates can be patched to control the dynamics of each voice, bend and affect the pitch of the oscillators, affect the cross-modulate the voices, modulate the waveshapers of each voice, affect the shift-register, and so on, in any configuration you’d like to patch. The touch plates are equally useful for manually playing drones using only the touch plates as they are for adding dynamics and variation into a rhythmic techno patch. The touch plates do not function as a traditional keyboard controller or traditionally drum pad, but instead as a way to introduce organic and gestural interactions through variable control voltage to influence the overall ecosystem of the Alea. Now available.

Description:


Alea Taction is a two voice semi-modular analog synthesizer with sine wave oscillators, waveshapers, low pass gates, LFOs, a stochastic shift register-based sequencer, and three touch plates for gestural influence. These elements work together as a standalone patchable instrument that is capable of everything from generative melodies and morphing drones to psychoacoustic percussion, silky sub basslines, esoteric techno, tactile improvisations and much more. Sonically, the Alea is dark, smooth, warm, and natural sounding. The sine wave oscillators have CV and FM inputs paired with attenuators for each input as well as a two different voltage controllable waveshapers per oscillator which affect the timbre of the oscillators - one type of waveshaper which adds subtle harmonics to shape the sine into a soft triangle wave, and the other waveshaper folds and shapes the phase of the sine. The oscillators also have sine outputs for modulating each other, as well as a vactrol-based vca which is hardwired as a bi-directional modulation index that can be opened via cv or gate signals for timbral cross-modulation between the two oscillators. The oscillators can be used as completely separate voices, or together with one voice acting as a primary oscillator and the other as a modulation oscillator. The two voices also have individual outputs. Each voice has a vactrol low pass gate with two inputs per LPG - one regular gate input which will provide sustain for the duration of the gate or cv signal, and one input which coverts the gate to a trigger for faster percussive sounds with no sustain and only decay. The LPGs can also be patched so that they are held open to create drones, or patched for amplitude modulation via one of the oscillators or modulation sources. The LPGs can also be help open and dynamically controlled by the touch plates via the LPG gate input. The three gold-plated touch plates of the Alea generate variable control voltage signals which can be patched to control various aspects of the system such as the amplitude, pitch, modulation, and cross-modulation of the voices as well as the the pattern and tempo of the shift register. The touch plates do not function as a traditional keyboard controller or traditional touch controller, but instead as a way to introduce organic and gestural interactions to influence the ecosystem of the Alea. The amount of control voltage which is produced as they are touched depends on factors such as the amount of skin that contacts the plate, the amount of pressure used, the as well as factors such as the temperature of your fingers, etc. Because of a build up of body heat and perspiration, the more you touch the plates, the more responsive they become. The Alea has two LFOs - a LFO with triangle and square wave outputs as well as a VCLFO with a triangle output. The Alea's sequencer is based around a four-stage shift register which is clocked by the VCLFO and collects data from one of the oscillators for probabilistic pattern generation. The shift register can also be clocked from external clock signals from other instruments. The shift register cycles through it's four stages as it collects on/off data on each clock pulse and creates different arrays of outcomes as it cycles. Once the Alea has been patched and knobs have been set - the shift register will continue to cycle through patterns and generate different numeric combinations of it's stages in unity or in abscense like a roll of the dice or a song of the birds.

Each Alea Taction includes a 18v center negatice DC power adapter.
The Alea Taction is housed in a 15” x 9’ x 2” bamboo boat with a matte PCB front panel.
Patch cables and output cables not included."

Ouroboros Gemini • DIY Semi-Modular Percussion and Noise Synthesizer • Rhythmic Demo


video upload by Ouroboros Electronics

"Gemini is a beginner-friendly DIY synthesizer existing at the crossroads of a primitive rhythm box and a chaotic west-coast system. With a low part count consisting only of common thru-hole components and a pre-drilled front panel intended for mountable legs; Gemini is a very approachable and ideal entry into the world of synth DIY while also being a worthwhile instrument in its own right that would still satisfy an advance builder and synthesist. Gemini consists of two individual resonant low pass filters which are each pinged by separate LFOs to create percussion such as clicks, crackles, pops and bubbling sounds in the vein of Serge and Hordijk sonics, as well as sounds akin to those of early drum machines. The LFOs each have gate outputs and rate modulation inputs, and there is a third, slower LFO with a gate output as well which can modulate either or both of the other LFOs. Using the banana jacks, the LFOs can be patched together to create syncopated rhythmic interplay between the two resonant voices or patched to create modulated patterns of spontaneity and unpredictability.

The resonance on the filters can also be brought into self-oscillation. Individual outputs allow the possibility of panning and processing each voice individually. It can also be connected via an optional ground jack for use when cross patching with other banana gear. The Gemini PCB and front panel set is now available for $50USD + $8.50 shipping within the US.

To order - email: ouroboros.electronics.us@gmail.com or visit the Ouroboros Electronics store on Reverb.com. Please visit www.ouroboros-electronics.com for more info including the BOM and a Q&A."

Ouroboros Phase Voice • Digital Phase Modulation Synthesizer


Ouroboros Electronics

"Ouroboros Phase Voice is a compact and tactile standalone digital synthesizer for sonic expression and exploration. It utilizes phase modulation synthesis, one of the strong suits of digital synthesis, for complex and lively sonics inspired by the Buchla 200e. The Phase Voice consists of a primary and modulation oscillator combo, an LFO for phase-width modulation, a pair of simple function generators for pitch modulation, and a variable rate pulser for triggering the voice’s envelope generator to create percussive sequences or to hold it open for sustained tones. Timbre-rich drones, hypnotic percussive and melodic patterns, and Buchla bongos are all possible. Six knobs control synthesis parameters and a seventh knob controls the master output volume. It has a mono 1/4” output jack and is powered by a 9v center negative DC adapter (not included). There is only one of these right now, but I plan to create more instruments based around this code in the future. This first iteration of the Phase Voice is now available for $225 + $20 insured shipping within the US. To order - DM or email ouroboros.electronics.us@gmail.com"

Ouroboros Lumen Spatial Voices • Gestural Synthesizer Demo


Ouroboros Electronics

"Lumen Spatial Voices:
The third instrument the Lumen series of one-off gestural synthesizers.
This one is the most complex of the three - consisting of two individual triangle wave oscillators which are panned hard left and hard right in the stereo field while in their default states. The knobs adjust the base frequencies of the oscillators, and the sensors control the rate at which they are gated and step through individual two-tone intervals. The three switches cross-modulate and affect the two voices in different ways via frequency modulation, timbre modulation, and overdrive while also drastically changing their relative positions in the stereo field. Percussive transients, stepped tones, stereo ripples, and complex modulation from chaotic and noisey to soft and subtle. A compact and expressive instrument for performance techniques and experimental sonics in the vein of west coast synthesis. A demo video is now up on Youtube. It is powered by a 9v battery, and the enclosure is made from Purpleheart and finished in boiled linseed oil with a powder coated steel bottom piece. This instrument is now available for $200 + $15 shipping within the US. To order: email ouroboros.electronics.us@gmail.com"

Ouroboros System I • OR Drone


Published on Mar 16, 2020 Ouroboros Electronics

Also see the Ouroboros Subharmonic Drone Synthesizer

"More info/order: www.ouroboros-electronics.com

System I OR drone patch - a patch made by sending two oscillators and an audio rate LFO into the OR logic. Two of the oscillators are sent through attenuators before going into the OR to control their individual levels and influence on the OR output. The OR output is sent into a mult which is split to both the mixer output and also to the third attenuator which is then patched into the cv input of one of the oscillators producing a form of frequency modulation where it is being modulated by the sum of all three OR’d oscillators. The attenuator adjusts the amount of FM/feedback modulation. Though OR logics are mainly thought of as gate combiners - they can also be useful to produce a spectrum of sounds from crystalline and metallic tones to harsh dissonance. This patch demonstrates just one of many ways that the OR function can be used in the audio range. Reverb added via Eventide Space."

Ouroboros Subharmonic Drone Synthesizer


Published on Feb 12, 2020 Ouroboros Electronics

Don't miss the third video in the playlist above: Ouroboros System I + TR-606 • Techno

"The Ouroboros Subharmonic Drone Instrument takes a fundamental frequency and produces 5 different tones which are each an octave below the one before it. The large knob sets the fundamental frequency, and then the row of six knobs adjusts the volume of the fundamental pitch and it’s five subharmonics. Below max volumes the square waves will sound softer and mix together smoothly, and at full volume they will become grittier. There is also has a 1-pole low pass filter and a master volume control. It has a 3.5mm mono jack output, and is powered by a 9v battery. It is housed in handmade cherry enclosures with a linseed oil finish and a stainless steel bottom.
The enclosure is very slim (slightly less than an inch thick) yet extremely sturdy due to rounded edges, a natural protective finish and steel backing.
This synth is a one-off and is now available for $200USD plus $8 shipping within the US or $28 shipped internationally. To order - contact ouroboros.electronics.us@gmail.com

Reverb added via Eventide Space in the first part of this demo. No effects or processing were used in the second segment."
