Meet the Apparatus Duophonic Tube Synthesizer
New independent Russian synthesizer manufacturer Eternal Engine, has released a very interesting video of its debut flagship synthesizer, the Apparatus, which drives its unique and powerful sound via gas-filled radio and vacuum tubes, in what the company says is: “in the spirit of the first half of the 20th century.” The acid 303 lines this thing can put out alone are something to be feared! It's got not just a very warm and complex sound, but it's also very aggressive and versatile at the same time.
Some key Features on the Apparatus are:
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
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
Powerful headphone amplifier, compatible with low impedance load
Analogue VU meter
