音光 (Onkou) - Light Controller for Modular Synthesizer (Breakbeat Demo)


Published on Mar 31, 2018 Takumi Ogata

"音光 (Onkou) is a light controller for Eurorack modular synthesizer system. The module has a camera that can detect X, Y, and Z positions as well as the hue color of the light. Each of these 4 parameters are mapped to a control voltage (4 separate control voltage outputs). The custom light source consists of on/off button, a knob for controlling the hue of the light, and a switch that is used to go back and forth between auto and manual mode. In auto-mode, the module takes in two separate control voltage inputs and send on/off and hue messages to the light source via bluetooth. In this demo video, wavetable control voltage from Qu-Bit Chance module is used to randomly change the hue color and sequenced gate control voltage is used for the light’s on/off pattern.

Hardware/Software used:
Make Noise Morphagene = main sound source controlled by the light controller
Qu-Bit Chance = random control voltage for light hue control
Make Noise Tempi = On/off message for the light
Ableton Live

"The Moog Opus 3 is a powerful, 3-voice (strings, brass and organ) Polyphonic synth that has those incredible, fat Moog filters (in stereo with panning!) and that vintage grit that makes this an endlessly toneful, useful and fun addition to your studio or to the stage. Kraftwerk, 808 State, the Rentals and many others have turned to the Opus 3 for its delicious tones. Detach from your endless plug-ins for a few hours and revel in the analog, tactile goodness of this classic, vintage Moog!"

"Excellent condition with some very light play wear and a couple dings in the wood sides. Overall condition is a collector-worthy 9 out of 10."

NOS Vintage Roland RS-202 Analog String Synth

"Purchased last year from a Roland dealer last as a NOS [New Old Stock] item (in his basement for 30 years, he had never sold it), this single owner RS-202 was recently serviced. Tech tested & replaced various components and all capacitors (including power supply) other than the key capacitors (each key has a capacitor). Key caps did not need to be done as all keys work.

The RS-202 is a classic. It really sounds excellent. Very nice with a phaser. Just a lot of fun. Brings to mind early Genesis/Tony Banks among others. And since this unit has been completely serviced, and has less then 10 total hours of playing time on it, it is currently functioning like a new machine."

"For sale a rare MFB Dominion X SED 3 VCO analog mono synth. It’s in perfect working order. There is a minor scratch on the right wooden end panel but is otherwise in perfect condition. This is the later version, with the SED style filter. Sounds incredible.

Includes power supply with US adaptor.

FEATURES:

The Dominion X offers 3 x oscillators for maximum flexibility. Each waveform can be varied in symmetry. Besides altering the pulse width of a rectangle, you may also continuously turn a saw tooth into a triangle and a triangle into a sine. All oscillators also offer ring modulation. In addition, VCO 2 and VCO 3 can be synced to VCO1. Finally, VCO3 can modulate the frequency of VCO 1 and VCO 2. The analogue oscillator circuit is processor-controlled for stable tuning. To complete the available sound sources, noise or an external audio input can be added to the VCOs in the Dominion X's mixer section.

The filter offers 6 x operation modes. Available are 3 x low pass variations with 12, 18 and 24 dB/oct. slopes. Also available are high pass-, band pass and a notch filter with slopes of 12 dB/oct. respectively 6 dB/oct. Variable filter modulations are possible via an invertible envelope, keyboard tracking, LFO, VCO, different MIDI controllers as well as by the use o the CV-input.
