MULTIBAND GRANULAR FX

GrainBrain

Splits your signal into independent frequency bands, then shreds each one into grains — its own LFO, spectrum view, and gate per band. The deepest knob-forest in the XNULLX family, built for players who want their hands on everything at once.

WHAT IT DOES

Built for texture

INDEPENDENT BAND STRIP

Split the signal across multiple bands, each with its own granular engine — sculpt highs into shimmer while keeping the low end intact.

PER-BAND LFO MODULATION

Every band carries its own modulation source, so grain density, size, and position can drift independently across the spectrum.

LIVE SPECTRUM VIEW

Watch the band split and grain activity in real time instead of guessing at crossover points.

GATING PER BAND

Keep grains from spawning on silence — each band's gate reacts to its own signal, not the full mix.
