Zoyd is a virtual Synthesizer. It has a rich feature set embedded in a semi-modular architecture to produce unique sonic experience. It doesn't try to simulate existing technology and has it's own character.
Zoyd has the capability to produce powerful, warm bass sounds, metallic chirp, silky pads and lots of destructive noise. Roundabout 80 parameters allow for extensible ways to tweak the sound.
Though Zoyd's internal workings are different in some way from common stuff, the knobs look quite familiar and invite for instant sound design.
