A firestorm of granular power

Grainferno is an advanced granular instrument built around a new way of synthesizing sound from existing audio. Its next-gen grain engine breaks your samples into microscopic fragments and rebuilds them into entirely new textures.

From pristine tonal clouds to experimental digital noise, Grainferno turns your sample library into an endless source of playable inspiration.

Make a synth from any sound

Grainferno can generate grains at speeds fast enough to cross into the audio range. At these rates, grains stop behaving like texture and start acting like oscillators—turning any audio file into a playable synth voice.

Even at audio rates, traces of the original sonic character remain, giving you unique synth building blocks with the spectral fingerprint of your source audio.

Add modulation and grain-level shaping to build ready-to-use granular synth tones that stay in tune with your song like a traditional synth.
