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, chain songs. Same instrument either way. Free to try. One purchase unlocks GranSample Pro — everything listed at the bottom. No subscription, no ads, no telemetry. NEW IN 1.5 Swing, in the app and in your host. Choke groups: hi-hats that cut each other off. Resample (Pro): record your beat back onto a pad as a bar-locked loop. A rebuilt AUv3 plugin editor. PATTERN BANK & SONG MODE Eight patterns per project (A–H). Switch live — the change waits for the bar end so the groove never stumbles. Then chain them into a song: tap letters to build, set repeats per section, loop or play once (song mode is Pro). Patterns, song and BPM save with the project. MODULATION MATRIX (PRO) LFO + ADSR envelope on 8 destinations per pad: grain position / size / pitch / density, volume, pan, pitch, playback start. Drag the envelope chart, set depth per lane — host-automatable in AUv3. SAMPLE CHOP (PRO) Slice any sample across the pads — equal grid, transient detection, or manual markers you drag. Audition before you commit; the grid shows where every slice lands. KIT SHARING Export any kit as a single .gskit file — samples, settings, effects, patterns. Send it anywhere. Importing is free for everyone; exporting is Pro. PAD NAMES, COLORS & CHOKE GROUPS Name your pads, pick from 8 colors, set one of 8 choke groups. AUv3 PLUGIN Load "nono.audio: GranSample" under AU Instruments in any AUv3 host. Same grid, Kits and engine, with Sound, Grain and Sequence tabs. 900 host-automatable parameters. Load your own samples without leaving the host. Sequencer locks to host transport; everything persists in the host project. LIBRARY Factory Kits + your Projects in one place — load, tweak, save. 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 — and you can watch them fire. CHROMATIC MODE Any pad becomes the root; the grid plays chromatically. STEP SEQUENCER Per-pad patterns at 16/32/64 steps, per-step velocity, drag-to-paint, swing. SAMPLE EDITOR Waveform view — drag the grain region, trim playback range, loop, reverse, normalize per pad. LINEAR or GRAN preview. Works inside the plugin too. EFFECTS Per-pad AND master bus. Reverb, Delay, Distortion, EQ, Compressor, Chorus, Filter — up to 8 per chain, automatable from any DAW. Hand-tuned presets; save your own. IPAD Pads bigger than an MPC; recorder, properties and sequencer get their own column. MIDI USB, Bluetooth (built-in browser), or virtual MIDI. MIDI Learn on every knob standalone, per-pad channel routing. The 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. Resample the master onto a pad, free or locked to 1–8 bars (Pro). 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 with bespoke granular settings. FREE TIER Pads 1–8 — drums and melody, enough to finish a track — with the full granular engine, effects, pattern bank, mixer, MIDI in/out. Same in standalone and AUv3. Kit import (.gskit) is free too. GRANSAMPLE PRO — ONE PURCHASE, NO SUBSCRIPTION All 16 pads unlocked everywhere — standalone AND AUv3 plugin Song mode — chain patterns into an arrangement Modulation matrix — LFO + envelope on 8 destinations per pad Sample chop to pads Resample to pads Kit export (.gskit) Per-pad ADSR envelope editor Custom backgrounds — wallpapers or your own photo, with dim and pad-opacity WAV / M4A export Made by one person who wanted a granular beat pad that fit on a phone — and in their DAW.
