Eternal Engine Apparatus Tube Synthesizer Hands-On Demo

Eternal Engine shared this hand-on demo of the Apparatus Tube Synthesizer.

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

    1. Anyone but Behringer. They suck. This synth’s incredible sound and beautiful appearance would be butchered by them. Their ugly-AF Murf (with 10k noise spike), clunky Linndrum & Klon debacle demonstrates B is a long way from their redemption arc.

      Admittedly it would be really cool to see something like this using more common & affordable tubes like ECC83s. I’d even take a proper reissued Korg EMX at this point.

        1. Admin: Personal attack (name-calling).

            1. B makes ugly cheap knockoffs with shitty designs
              Just because you bought into them doesn’t change that.
              Wear it with pride.

      1. Behringers are cheap enough that you can mod them without feeling much risk. Seen a lot of cool mods for their desktop semi-modulars… I mean, it’s just standard cheeks with holes… align and put on some walnut or something lol.

        And check out maffez synth mods for circuit modding.

    1. Probably the cheapest place to buy from now!

      Trump’s put a tax on imports from nearly ever country in the world…except for Russia. Trump’s to much of a wimp to stand up to Putin.

  1. Honestly 2k is significantly less than I’d expected. They could have asked for 3 and I think the same market would have obliged.
