NewA 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.
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.
AUv3 INSTRUMENT EXTENSION Load GranSample inside GarageBand, AUM, Logic, Drambo, Loopy Pro, or any other AUv3 host. Same 4×4 grid, same 10 factory Kits, same granular engine. The plugin shows up as "GranSample" under AU Instruments. iPhone and iPad both, ~80 MB process budget. 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. Save your DAW project, everything's back exactly where you left it.
LIBRARY — UNIFIED PROJECT MODEL Tap the project name in the top bar to open the Library. Ten factory Kits + your own saved Projects, one screen. Load a Kit, tweak it, name it, save it. The red dot next to the project name tells you when work is unsaved; loading another Kit prompts you to save first. Settings is now just settings — every project lifecycle action lives in the Library. No more silent envelope/playback resets when you switch Kits — the full state saves and restores cleanly.
MASTER FX A new Master FX icon next to the Mixer in the top toolbar. Global reverb, glue compressor, mix-bus EQ — one tap to reach. Same chain editor as per-pad FX, just at the master scope. Persists in the project file.
EFFECT PRESETS Each effect ships hand-tuned factory presets — Reverb (Plate / Hall / Spring / Tape / Cathedral), Delay (Slap / Long Echo / Ping-Pong / Tape / Dub), Distortion / EQ / Compressor / Chorus / Filter, ~30 in total. Tap a chip to apply, tweak the knobs, save your own with "+ Save". User presets live in app documents — they survive across projects. Long-press any factory preset to duplicate-and-edit; long-press a user preset to rename or delete.
EQ + FILTER CURVES The EQ and Filter editors now draw their transfer curve in real time. Drag the handle to set frequency + gain together (or frequency + resonance for filters). The curve shape lets you see the parameter relationships you used to have to imagine. iPad: pinch to control EQ bandwidth. Knobs still there for fine-tune.
STANDALONE BUG FIXES — Mic recordings now persist to disk. Project save / load / Kit switch keeps the audio (was lost before). — Switching projects no longer leaks the previous project's audio into empty pads. — Pad Properties gains an Output Bus picker (Main / Group 1-4).
UNDER THE HOOD Lock-free atomic parameter bridge unchanged. AUv3 sample-accurate trigger + host-clock sync. EffectPresetLibrary is write-before-commit so a failed disk write never leaves UI state ahead of disk. Curve math is pure and unit-tested; gestures route through the same updateParameter path knobs use, so audio + UI stay in sync. ~175 unit + integration tests now cover the new surfaces.
NEXT Sample chop-to-pads (slice a long sample across the grid, transient-aligned). Per-pad effects parameters into the AUParameter tree. More factory Kits.
There are purchases inside. The application is still raw. It didn't suit me. 😕
