Taking the classic analog sound of the legendary silver box into the future, PHOSCYON offers an unmatched sound together with advanced features such as a state of the art Distortion unit; fully user configurable BPM sync'd Arpeggiator and Randomizer; a unique 'Play Live' mode; vintage arrangement and pattern builder, full MIDI CC support and, to top it off, the most authentic 18db/oct low pass filter ever created!
Diehard fans of the original Bass Line will be blown away with PHOSCYON’s uncanny emulation of the classic and will also marvel at the ease with which new sounds can be crafted, sounds that were not possible on the original. PHOSCYON gives you access authentic vintage sounds at a fraction of the cost of the real thing. With the familiar Bass Line interface coupled with the added sound generation tools, we at D16 Group feel that PHOSCYON is quite simply in a class of its own.
PHOSCYON's designers are also musicians who believe that in order for electronic music to stay relevant, it needs to evolve – just like any other genre. Our approach is to give forward thinking musicians and producers the tools they need to craft the sounds they want. Whether it’s Techno, Acid, Triphop, IDM, D&B, Ambient, or any other kind of genre-bending music, PHOSCYON will take your sound further. 



Phoscyon is a vintage analog modeled Bassline synthesizer with a unique low pass filter with an 18db/oct dumping and constant resonance amplitude throughout the entire frequency domain. The filter sounds phenomenal! Hear that squelch and you’ll swear its analog! We’ve also equipped it with a fully customizable integrated arpeggiator (essential in electronic music) as well as an exhaustively analog modeled distortion effect, crucial for those screaming acid bass lines!

» Hosting all the features that made the 303 king, plus some massive improvements after years of tweaking, this emulator may just be the best reproduction ever wired. [...] Fatboy Slim might just have to change his track to, “Everybody needs a Phoscyon!” «
