Four independent tracks of granular synthesis, sampling and effects
Grainstorm plays a sample as grains, on four independent tracks, live — and every grain gets its own effect chain. Any two tracks can be merged into one sound by cross-synthesis, in real time.
It is also a sample editor, a looper with continuous tape speed, and a synthesizer that needs no sample at all. Each track then runs into a full effects suite of its own — EQ, dynamics, vocoders, convolution, spectral processing and more — for sound design work down to the single grain.
See It Running
Load a sample, set a loop, and granulate it in real time. The waveform view shows exactly where each grain is being read, so you can hear and see the same thing at once.
Tape Mode
Switch granulation off and Grainstorm works as a looper and tape machine instead. Playback speed is continuous rather than stepped, with high-quality resampling behind it, so moving the speed stays clean instead of degrading as you go.
Loop points can be repositioned while the transport keeps running, with dedicated loop modes to go with them.
Edit Your Samples
Grainstorm is a sample editor as well as a granular engine. Cut, copy, paste and insert silence, fade in and out, reverse or maximize — and apply the grain envelope straight to the waveform. Every edit is undoable, so you can work destructively without committing to anything.
Grain Effects And Synthesis
Every single grain gets its own effect chain — filters, band pass, reverb, modal resonators, ring modulation, pitch detection and formant processing, all applied per grain rather than to the finished sound. Grains do not have to come from a sample either: VCO, noise, buzz and modal modes synthesize them outright, with a sequencer, arpeggiator and random-pitch modes driving how they are placed.
This is only the grain stage. Each track then runs into a full effects suite of its own — EQ, dynamics, saturation, delays, reverbs, phasers, vocoders, convolution and many more.
Spectral Processing
Spectral processing works on the spectrum rather than the waveform: phase manipulation, formant and frequency warping, oscillator bank resynthesis and harmonic/percussive separation among them, at FFT sizes you choose.
Cross synthesis combines two tracks into one sound, in real time, with nine algorithms to choose between.
