GranSample - Granular Sampler

1.3.1: modulation matrix, sample chop-to-pads, .gskit kit sharing, pad names & colors. Pro now $3.99 — rising to $5.99 on Jul 30; existing buyers upgrade free.

A 16-pad sampler with a granular engine underneath. Standalone app + AUv3 plugin for GarageBand / Logic / AUM / Drambo / Loopy Pro. Tap pads, sculpt textures, sequence patterns. Same instrument either way.

Free to try. GranSample Pro ($3.99, one-time) unlocks all 16 pads, the modulation matrix, sample chop, kit export, and WAV/M4A export. No subscription, no ads, no telemetry.

MODULATION MATRIX — NEW IN 1.3 (PRO)

LFO + ADSR envelope on 8 destinations per pad: grain position / size / pitch / density, volume, pan, semitone pitch, playback start. Drag the envelope chart, set depth per lane — all host-automatable in AUv3.

SAMPLE CHOP — NEW IN 1.3 (PRO)

Slice any sample across the pads — equal grid, transient detection, or manual markers you drag to move and flick off to delete. Audition before you commit; the grid shows where every slice lands.

KIT SHARING — NEW IN 1.3

Export any kit as a single .gskit file — samples, settings, effects, patterns, all of it. Send it anywhere. Importing is free for everyone; exporting is Pro.

PAD NAMES & COLORS — NEW IN 1.3

Name your pads, pick from 8 colors.

AUv3 PLUGIN

Load "Digilog: GranSample" under AU Instruments in any AUv3 host. Same 4×4 grid, same Kits, same engine. 900 host-automatable parameters — master, every per-pad slider, every modulation routing. Sequencer locks to host transport; MIDI routes through the host. Kit + pattern + sliders persist in the host project.

LIBRARY

Tap the project name in the top bar: ten factory Kits + your saved Projects in one place. Load, tweak, save as your own — then share it as a .gskit.

GRANULAR ENGINE

Eight knobs per pad. Position scans the sample; grain size + density set the texture from pebbles to glass. Pitch + jitter, spray + stereo spread, four window shapes, an ADSR cloud envelope, Freeze for infinite sustain. 128 grains per voice, lock-free render.

CHROMATIC MODE

Pick any pad as the root and the grid plays as a chromatic keyboard. Every pad shows its note.

STEP SEQUENCER

Per-pad patterns at 16/32/64 steps, per-step velocity, drag-to-paint. Standalone runs its own clock; AUv3 syncs to host transport.

SAMPLE EDITOR

Waveform view — drag the grain region, trim playback range, loop, reverse, normalize per pad. LINEAR or GRAN preview. Works inside the AUv3 plugin too.

EFFECTS

Per-pad AND master bus. Reverb, Delay, Distortion, EQ, Compressor, Chorus, Filter — up to 8 per chain, automatable from any DAW. Each effect ships hand-tuned factory presets; save and recall your own. EQ and Filter draw their curve in real time — drag the handle to set frequency + gain together.

IPAD LANDSCAPE

Pads stretch larger than a hardware MPC. Recorder, properties panel, and sequencer sit in a dedicated right column instead of stacking.

MIDI

USB, Bluetooth (built-in browser), or virtual MIDI. MIDI Learn on every knob standalone, per-pad channel routing. The AUv3 plugin routes MIDI in through the host and emits MIDI out for pad taps.

RECORDING

60 seconds from the mic straight into a pad with a live waveform (standalone). Master bounces to WAV/M4A (Pro).

10 FACTORY KITS, 16 SAMPLES

Late Night Room, Outer Space, Neon City, Midnight Dub, Tape Machine, Crystal Cave, and more. Each Kit wires drums / melodic / textural samples with bespoke granular settings.

UNDER THE HOOD

AVAudioEngine. Lock-free parameter bridge, Hermite pitch interpolation, per-voice declick, zero-allocation render path. AUv3 sample-accurate trigger + host-clock sync.

FREE TIER

Pads 1–4 with the full granular engine, effects, sequencer, mixer, MIDI in/out — same in standalone and AUv3. Kit import (.gskit) is free too.
