80
Grains per voice
FRMS.
Any sound. Endlessly reshaped.
A granular synthesizer that turns any sample into a playable instrument. Drop a vocal, a field recording, a chord — break it into grains and find textures that didn't exist a minute ago.
[ OVERVIEW ]
The short version.
FRMS slices any sample into clouds of grains — stretched, scattered and re-pitched into living, evolving textures you can play like an instrument.
A granular synthesizer for desktop, iOS and Android. Up to four layers per patch, each with its own engine, filter and envelopes — plus a modulation matrix and effects that take a raw sample to a finished patch without leaving the plugin.

01 · What it is
Any sample, made playable.
Drop a vocal, a field recording, a chord. FRMS breaks it into up to 80 grains per voice and spreads it across the keyboard as an instrument.
02 · What it does
Textures that never sit still.
Position, density, spray, pitch and jitter sculpt the grain cloud, while envelopes and the modulation matrix keep it evolving as you play.
03 · Why it's different
Deep engine, fast results.
163 factory presets and eighteen expansion packs get you to a finished sound in minutes — and the engine rewards going deeper.

FRMS, in motion.
[ ENGINE ]
The pieces that make grains sing.
01 · feature
Up to 80 grains per voice
Fill the air. Stack dozens of grains for shimmering clouds, or thin out to a single tone — density is just a knob away.
02 · feature
Position scrub & freeze
Move freely through any sample. Lock the playhead, spray grains around it, freeze a single moment in time and stretch it forever.
03 · feature
Spray, pitch, jitter
Three knobs that turn any sample into something else. Detune grains, scatter their start points, randomise their length.
04 · feature
Per-grain envelope
Shape each grain with a configurable Hann window. The difference between musical and broken is one curve.
[ WORKFLOW ]
Three steps from sample to instrument.
01
Drop a sample.
Drag any audio file onto FRMS — a vocal, a field recording, a chord stab. The waveform appears, transients marked, ready to play.
02
Break it into grains.
Set position, density and pitch. Spray grains across the sample, freeze a single moment, scatter them in stereo. Listen as it transforms.
03
Play it like an instrument.
Map a controller, route to your DAW, layer with FX. The sample is now a synth — every key a new texture, every note alive.

[ TESTIMONIALS ]
Producers who use it.
“Andrián Pertout · Composer, PhD
After discovering VS, I tried FRMS and found it ideal for blending live acoustic instruments with electronics. As a contemporary composer, I value its creative potential—granular, FM, and subtractive synthesis—to generate evolving textures. The preset libraries are inspiring, and the ability to granulate any sound source, even live input, is incredibly powerful.
