Grainfold is a granular synth that turns any sound into an instrument. Record your voice, a glass or the street outside, or import a file, and shape it into loops, playable chords, melodies and evolving clouds of grains. A GRANULAR SYNTH YOU CAN PLAY Granular synthesis cuts a sound into tiny grains and plays them back in new ways. Grainfold makes it hands-on: set how long each grain lasts, how often grains spawn, where they come from and how far they scatter. Reverse them, spread them across the stereo field, give them a shape from smooth to plucked, and play them from the keyboard, MIDI or your fingertips. FOUR REGIONS, LOOP OR GRAIN Mark up to four parts of a sound, each with its own mode, pitch, envelopes, filter and modulation. LOOP repeats a region with fades and crossfade; GRAIN turns it into textures, pulses and harmonies. MELODIES WITHOUT A KEYBOARD The step sequencer plays sixteen steps of any scale in time with the tempo. Or let every grain choose its note: random notes of a scale, a wandering line, a melody that comes home to the key, or a slowly evolving motif. SHAKE TO PLAY In SHAKE mode, balls bounce around the sound as you shake and tip your phone, like a pong ball off the edges of the screen, and the grains follow them. HARDWARE LOOK, CRT SCREEN A silver metal body that catches the light as you tilt your phone, solid keys, big knobs and a waveform on a glowing CRT screen, with bloom and scanlines. Each grain is a spark, as big as it is long. A small spectrogram, an oscilloscope and a 3D spectrogram show what you hear. LOCKED TO THE BEAT Type or tap a BPM. Spawn grains on the beat, set their length, the scan, the LFOs and the delay in note values, and see where every beat falls. A metronome keeps time in any meter. In an Audio Unit host, Grainfold follows the host tempo. MOVEMENT AND EFFECTS Two LFOs per region, ADSR envelopes for notes and the filter, PITCH that keeps timing, SPEED that keeps pitch. Filters, harmonic LAYERS, drive, chorus, DIFFUSE, delay and reverb. PLAY WITH TOUCH OR MIDI In PERFORM, each finger plays a region and moves two parameters; LATCH holds sounds and MOTION loops your gestures. Chords of up to twelve notes from the on-screen keyboard or MIDI, with velocity, sustain, pitch bend and MIDI Learn.
