Describe a sound. VS-1 builds it.
Type a prompt — "warm 80s analog pad", "gritty FM bass",
"plucked nylon guitar" — and VS-1's cloud AI returns an
editable preset across five sound engines: Subtractive,
FM, Karplus-Strong, Granular, and Additive. Refine the
patch with another prompt, or dive into the panel and
edit every knob by hand.
VS-1 is built for producers who think in sounds, not
parameters. Start from a blank patch or one of 105
factory presets — every engine, every modulation slot,
and every effect is fully exposed for hands-on editing.
