"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"
