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.
Deep drag-and-drop modulation
Grainferno comes alive in motion, with nearly every parameter available for modulation. Three envelopes, three LFOs, and three random generators give you deep control over evolving behavior, making Grainferno a powerful platform for dynamic sound design. A drag-and-drop workflow makes it fast and intuitive to connect any modulation source to any destination—including cross-modulation between modulators themselves.
Stack as many assignments as you like to let Grainferno’s sound continuously unfold with new variations on the source material.
Sculpt, morph and shape each grain
Grainferno can generate grains from two independent source files and morph between them in real time. With seven unique modes to morph between signals, you can create granular soundscapes that continuously shift between the character of each sample.
Shape each grain at the point of generation with Grainferno’s per-grain effects to energize, destabilize and transform your results even further. Perfect for hybrid instruments, seasick drones and textures outside the realm of traditional synthesis.
Give new life to your samples
With vastly different results depending on the source material you feed in, Grainferno lets you explore and transform your existing sample collection.
Drag and drop any audio file into Grainferno - or a stem from your latest track - to deconstruct and rebuild it into something entirely new.
Start new tracks, build unique signature sounds, or generate elevating textures for your songs from their existing elements.
If you rely on loops/samples in your music production, Grainferno lets you add a personal touch to stand out from the crowd.
Essential effects for sound design
Grainferno includes a powerful suite of onboard effects designed to shape and extend its granular engine.
From ambient delay and reverb to analog-inspired modulation and multimode saturation, each effect is built for creative sound design rather than static post-processing.
With a reorderable signal chain and nearly all parameters available for modulation, Grainferno’s effects become part of the instrument itself.
Packed with 1.5GB of new inspiration
Grainferno includes a large collection of handcrafted presets and royalty free samples from world class sound designers to help you navigate its entire sonic range. Use the Play View, with four powerful macro controls, to audition and tweak the factory content.
With 325 presets you’ll find a stunning array of prebuilt synthesis ideas to kickstart inspiration in your tracks.
In addition, Grainferno’s built-in sample library includes 378 eclectic audio files that serve as the perfect raw material to start experimenting with the granular engine.
Finally, the six included template configurations in the plugin's bottom panel let you quickly explore the core applications of granular synthesis with any sample loaded.

Absolutely. Grainferno is built to let you explore any sample in your collection as the raw material for synthesis.
Simply drag and drop any WAV, AIFF, FLAC, MP3 or Ogg Vorbis file from your DAW or any folder on your desktop to add it to Grainferno and start using it to generate new sounds.
Grainferno can instantly play in tune regardless of the source sample’s pitch when set for audio rate grain generation.
This means that new grains are generated so rapidly that they create their own pitched tone like an oscillator.
To make any sample in tune using this technique, select Key-mapped Octave mode in the Rate knob dropdown menu and use a high Rate value.
To play in tune at lower Rate values, use the Auto Pitch function to tune your source sample to the nearest C, or manually retune it as needed.
After tuning, select a Key-mapped mode of the Grains Menu pitch control to generate new grains at the pitch of incoming MIDI notes.
Yes. Grainferno's included factory samples are royalty-free for use in your own musical works.
