"Hello guys! You've been asking for a long time, and I finally got around to recording the tube synthesizer MARS through a line-in. Sorry I couldn't do it earlier; there was a lot of organizational work to handle in these challenging times. This is just a small first attempt."

A few pics and details follow. You can find additional posts featuring the MARS Tube Synthesizer here.



Polyphonic synthesizer based on vacuum tubes.

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
Priced at $2199

"Apparatus synthesizer sound path with TDA1543 DAC wavetable oscillators"

Project MARS vs Apparatus Tube VCF

Eternal Engine EMI

"MARS Wavetable oscillators engine output to NOS DAC TDA1543 and directly to tube filter input. It use vactrols to control presets.

MARS is a synthesizer engine with 4 wavetable oscillators (FM, offset, and phase restart) that are controlled independently, much like it was implemented in Korg Mono/Poly. Also available a modulation matrix all to all, two multi-function LFOs, and two HoldADSR envelopes."

MARS appears to be new. See Eternal Engine EMI label below for additional posts featuring them.

Side note: Anyone remember the CME controllers? I haven't seen on in ages.
