APPARATUS
Tube Synthesizer
The first duophonic synthesizer based on vacuum and gas-filled radio tubes.
Apparatus is the first duophonic synthesizer. The audio path of the instrument, completely created on the basis of vacuum and gas-filled radio tubes using circuitry solutions in the spirit of the first half of the 20th century, is controlled by a modern powerful processor based on the ARM core, which ensures stability of characteristics and instant response to the artist's manipulations. All synthesizers are hand-assembled and produced in a limited edition.

MARS
Polyphonic Tube Synthesizer
COMING SOON
The first 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.
