Polyphonic Tube Synthesizer In Action

Eternal Engine has posted this video of their MARS polyphonic synthesizer that's based around vacuum tubes. It's a test of one of their units before shipping. This is what they have to say about MARS...

MARS - the first polyphonic synthesizer based on vacuum tubes. The power and flexibility of oscillators based on the famous R-2R DAC TDA1387, combined with the original fully tube audio path based on the APPARATUS synthesizer circuit, allow you to create a wide range of sounds from punchy aggressive FM leads and acid basslines to soft classic pads and strings. The synthesizer supports full software control and easily integrates into any DAW using the original plugin. All synthesizers are assembled by hand and produced in limited quantities.

Specifications:

•     Compact RACK format, 5 units high
•     Fully tube audio path based on the APPARATUS synthesizer
•     Four oscillators operating in modes: BASIC (Sine, Triangle, Sawtooth, Fixed Pulse Width 1/2, 1/4, 1/8); PULSE; ENSEMBLE and Noise with Hi-Pass and Low-Pass filters
•     Voltage-controlled tube filter of the second order with self-oscillation with overload
•     Voltage-controlled amplifier, following the traditional architecture of tube opto compressors
•     Triode asymmetric overdrive
•     Indicator based on Nixie lamps
•     Full software control using the plugin
•     Four channels of 4xCV and Gate for integration with Eurorack format synthesizers
•     External Input for processing the audio signal of external audio devices
•     Two HADSR envelope generators with pre-delay and multiple retriggers
•     Sub-audio frequency generator LFO with restart and synchronization Clock, smooth waveform transition sawtooth-triangle-sawtooth, pulse-square-pulse, as well as Sample & Hold and Noise with reconfigurable Hi-Pass and Low-Pass filters
•     Auto and continuous modes of portamento / legato
•     Mono, duo, and 4-voice polyphony modes
•     Flexible 4-channel modulation matrix
•     Plugin for integration with DAW
•     PC connection with galvanic isolation
