"The first Russian duophonic synthesizer based on vacuum and gas-filled radio tubes. Apparatus is the first Russian duophonic synthesizer. The audio path of the instrument, completely created on the basis of vacuum and gas-filled radio tubes using circuitry solutions in the spirit of the first half of the 20th century, is controlled by a modern powerful processor based on the ARM core, which ensures stability of characteristics and instant response to the artist's manipulations. All synthesizers are hand-assembled and produced in a limited edition.

Specification:
kenoton rectifier power supply

audio path based entirely on radio tubes

two independent thyratron oscillators with quartz frequency stabilization, which ensures frequency accuracy throughout the entire operating range

voltage-controlled second order vactrol filter with the possibility of self-oscillation and overdrive

voltage-controlled amplifier, based on the traditional schematic of tube opto compressors

triode asymmetric overdrive

analogue VU meter

filter cutoff frequency control by analog pedal

CV inputs to control the filter cutoff frequency and amplifier amplitude
External Input for signal processing from external audio devices

velocity-sensitive ADSR envelope generator with two trigger modes

MIDI Clock synchronizable low-frequency oscillator with retrigger option and smooth waveform morphing: saw-triangle-reverse saw in triangle mode or pulse width modulation in square wave mode, sample & hold

auto and continuous modes of portamento / legato

monophonic and duophonic mode

responds to MIDI controls Pitch Bend, Mod Wheel, Velocity

MIDI channel switching with the Learn button

galvanic isolated USB port

powerful headphone amplifier, compatible with low impedance load

FAQ
Tubes are removed during transportation

The kit includes a set of spare tubes (one tube of each type)
You can order the new tubes from us

MIDI over USB protocol implementation does not require an external driver for Windows or Mac OS"
