The things people ask before they download.
Yes — GranSample is free to download, and the sampler, granular engine, mic recorder, effects, and step sequencer are all playable out of the box. An optional one-time GranSample Pro upgrade unlocks all 16 pads, Scale Lock pitch correction, the Modulation Matrix, Sample Chop, and WAV/M4A export. No subscription, no ads, no account.
Granular synthesis chops a sound into tiny fragments called grains and replays them in clouds — letting you stretch, freeze, pitch, and scatter audio in ways a normal sampler can't. In GranSample, five knobs (Size, Density, Pitch, Spray, Spread) plus an ADSR envelope and four window shapes let you sculpt any recording grain by grain, up to 128 grains at once.
Yes. GranSample ships as an AUv3 plugin, so it runs inside any AUv3 host — Logic Pro, GarageBand, AUM, Cubasis, and more. Per-pad parameters automate from the host, and MIDI Settings live inside the extension itself.
Yes. Connect any external MIDI controller to trigger pads with velocity sensitivity and per-pad note mapping. Chromatic mode fans a single sample across all 16 pads at semitone pitches, turning the grid into a playable instrument.
Yes — GranSample is universal and runs on any iPhone or iPad with iOS 16 or later. iPad gets a native landscape layout where the pad grid, properties panel, and step sequencer share the screen without scrolling.
Absolutely. Record up to 60 seconds from your device mic, or import WAV, AIFF, M4A, and MP3 files. Scale Lock can pitch your source into any root and scale so it lands perfectly in tune before it hits a pad.
