GranSample - Granular Sampler

Beat Pad, FX & Step Sequencer

Free · In‑App Purchases · Designed for iPad. Not verified for macOS.

1.2.4: scale-locked pitch jitter (Pro), per-grain size/rate/probability randomization, and a fourth LFO destination for density. Musical granular by design. 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 and WAV/M4A export. No subscription, no ads, no telemetry. ■ AUv3 PLUGIN — NEW IN 1.2 Load "GranSample" under AU Instruments in any AUv3 host. Same 4×4 grid, same 10 factory Kits, same engine. 420 host-automatable parameters cover master + every per-pad slider. Sequencer locks to host transport; tempo changes propagate. MIDI in routes through the host; MIDI out emits NoteOn so pad taps can drive other instruments. Kit + pattern + sliders persist in the host project. ■ LIBRARY — NEW IN 1.2 Tap the project name in the top bar to open the Library. Ten factory Kits + your own saved Projects in one place. Load, tweak, save as your own. Red dot tells you when work is unsaved; loading another Kit prompts to save first. ■ GRANULAR ENGINE Eight knobs per pad. Position scans through the sample. Grain size + density set the texture from pebbles to glass. Pitch + jitter, spray + stereo spread, four window shapes, Freeze for infinite sustain. Up to 128 grains per voice; lock-free render so it stays musical when you push it. ■ 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, or 64 steps with per-step velocity, drag-to-paint. Standalone runs its own clock; the AUv3 plugin syncs to host transport. ■ SAMPLE EDITOR Waveform view, drag the grain region, trim playback range. LINEAR or GRAN preview at the top bar. Loop, reverse, normalize per pad. Inside the AUv3 plugin too — handles bound to host-automatable parameters. ■ ADSR ENVELOPE (PRO) Per-pad attack/decay/sustain/release. Drag the live chart. ■ EFFECTS — REWORKED IN 1.2 Per-pad AND master bus. Reverb, Delay, Distortion, EQ, Compressor, Chorus, Filter. Master FX is now one tap from the top toolbar. Each effect ships ~5 hand-tuned factory presets (Plate / Hall / Slap / Punchy Drum / Bass Boost / LP Sweep…); save your own and recall per pad or master. EQ and Filter draw their transfer curve in real time — drag the handle to set frequency + gain together. iPad pinches the curve for bandwidth. Up to 8 effects per chain, automatable from any DAW. ■ MIDI USB or Lightning MIDI keyboard, Bluetooth MIDI via the built-in browser, or virtual MIDI from other apps. Inside the AUv3 plugin, MIDI in routes through the host; the plugin emits MIDI out for taps + future sequencer triggers. MIDI Learn on every knob standalone. Per-pad channel routing. ■ RECORDING 60 seconds from the built-in mic straight into a pad (standalone). Full master bounces to WAV/M4A (Pro). ■ 10 FACTORY KITS, 16 SAMPLES Late Night Room, Outer Space, Neon City, Forest Stream, Toy Factory, Midnight Dub, Tape Machine, Crystal Cave, Sunrise Choir, Dark Matter. Each Kit wires drums / melodic / textural samples with bespoke granular settings. Browse from the Library; reload, fork, save your own. ■ UNDER THE HOOD AVAudioEngine. Lock-free atomic parameter bridge. Hermite pitch interpolation. Per-voice declick. Cross-pad RMS compensation. BT-aware IO buffer negotiation. Zero-allocation render path. AUv3 sample-accurate trigger, host-clock sync, full state preset. ■ FREE TIER Pads 1–4 (Kick, Snare, Hi-Hat, Sub Bass) — same restriction in standalone and AUv3 plugin. Full granular engine, effects, sequencer, mixer, MIDI in/out. GRANSAMPLE PRO — $3.99, one-time All 16 pads unlocked everywhere (Bass, Piano, Rhodes, Guitar, Synth Pad, Vocal, Strings, Rain, Bowl, more) — standalone AND AUv3 plugin Per-pad ADSR envelope editor WAV / M4A export Made by one person who wanted a granular beat pad that fit on a phone — and now in their DAW too.

1.2.4 — musical granular. Scale-lock pitch jitter, per-grain organic randomization on size / rate / probability, and a fourth LFO destination for density. PITCH SCALE-LOCK (PRO) Per-grain pitch jitter now snaps to a scale: Major, Minor, Pentatonic Major, Pentatonic Minor, Chromatic, or Off (continuous detune, the historical behaviour). Jitter range expanded to 24 semitones so scale-lock has room to range a full octave — set jitter wide and listen to the cloud arpeggiate itself across the chosen mode. Same idea as Output's Portal — random pitch that stays musical instead of detuned. PER-GRAIN JITTER Three new knobs in the GRAN tab. Size Jit nudges each grain ± a fraction of nominal length. Rate Jit jitters the spawn interval for drunk timing. Prob is a 0-100% gate — each scheduled grain rolls a dice; misses become silent gaps. Combined at low density they turn a smooth wash into a Borderlands-style organic grain cloud, without changing the average rate noticeably. LFO — GRAIN DENSITY DESTINATION The Granular LFO gains a fourth destination: GRAIN DEN, bipolar ± 2-octave (logarithmic) sweep of density. Joins position / size / pitch. Sample-and-hold + density makes for stuttering rhythms that re-cast every beat. UNDER THE HOOD AUv3 hosts gain 80 new automation targets (5 per pad × 16). Pitch scale, grain size jitter, rate jitter, trigger probability, and density-destination LFO depth are all individually automatable from Logic / AUM / GarageBand / Drambo / Loopy Pro. 628 host-automatable parameters total. NEXT Still working on sample chop-to-pads (slice a long sample across the grid, transient-aligned). Bug reports and feature ideas welcome — email's open. An App Store review goes a long way too. — zhi
