The Apparatus Tube Synthesizer is described as ‘The first duophonic synthesizer based on vacuum and gas-filled radio tubes.”
Features:
- 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 filter with the possibility of self-oscillation and overdrive
- Voltage-controlled amplifier, based on the traditional schematic of tube opto compressors
- Triode asymmetric overdrive
- Analog VU meter
- CV / Gate inputs to control the oscillators pitch (OSC-1, OSC-2 CVs), filter cutoff frequency (VCF CV) and amplifier amplitude (VCA CV)
- External Input for signal processing from external audio devices
- velocity-sensitive ADSR envelope generator with two trigger modes
- 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 Control Changes Pitch Bend, Mod Wheel, Velocity
- Channel switching with the Learn button
- Galvanic isolated PC connection port
- Powerful headphone amplifier, compatible with low impedance load
