Trogotronic ms679 Tube Mini Synth

   (0 reviews)

In rare moments of clarity we’ve long glimpsed a brutish dream burning in the solder smoke: A compact valve synth’ capable of the specular analog displays that make high voltage tubes essential for any serious electronic music aficionado. Building upon the legacy of the 676 Fury the 679 Gran Fury has 8x the patches, 150% more oscillating power, 120% more cv inputs & adds a synth bypass mode to double as a filthy tube distortion unit—repackaged in a low profile, rugged cast aluminum case. Further we applied a button interface pioneered on our 669 MiniSynth to enable unprecedented rapid attack. The sound? Curiously akin to R. Lee Ermey switching on the kilowatt floods & screaming through an Orange Full-stack set to “11” first thing the morning after an all-night gin bender; i.e. relentless punishment applied to all head-holes within audio range. Gran Fury’s feature list picks up where Fury’s left off:

Like any Trogotronic worth its salt the 679 Gran Fury’s functions are not conservative… Meaning, while there are 3 Main Oscillators, other parts of the circuit can command more complicated frequencies in an intuitive manner. Similarly the Main Oscillators themselves may be applied as filters serving to broaden the utility of the instrument even more so. Its High Voltage Twin-Triode Vacuum Tube is NOT a hard to find, out of production arcane device; on the contrary the tube is in CURRENT PRODUCTION WORLDWIDE from every factory that is making tubes in the 21st Century AND the 679 is plug & play compatible with two other current production tubes with alternate gain profiles—which means delicately alternate sonic profiles when implemented. The Gran Fury is compatible with modular synth racks of sequencers, envelopes etc. via 6 CV inputs—3 addressable & interruptible by the Performance Button Array. The dedicated Tube-Distortion Mode is icing on the cake but the most valuable new feature is the ability to shut its subhuman cry hole at will via the Thumb-Button/Toggle Mute-Circuit. Anyone within earshot will undoubtedly agree.
