"We took our 20+ years of experience in vacuum-tube electronic music, and used it to make the most exciting instrument in the history of Metasonix. The S-2000 is not merely a new repackaging of old designs. It is a revolution, and a game changer.
The S-2000 was made to be as easy to use as possible. Just plug in power, plug in an amplifier, wait 30 seconds for the real new-old-stock vacuum tubes to warm up, and start playing it. The built-in 400mm ribbon controller is instantly responsive, and needs no special treatment. No trimpots, no fiddling with MIDI interfaces or fighting with fistfuls of cables. The misery has been engineered out.

two all-tube oscillator/filter “operators”, with resonance variable from flat response to deep oscillation. Waveshape is variable from clean sine wave to a distinctive distorted square/pulse wave. Resonate both for FM sound effects.
an all-tube VCA.
three contour generators:
