Same engine either way. Free to try. One purchase unlocks GranSample Pro — everything listed at the bottom. No subscription, no ads, no telemetry. NEW IN 1.7 Your Projects in the plugin: open them from the host's preset menu or the plugin's library, save new ones. Free. Export to Files: a free .gskit copy of any project. PATTERN BANK & SONG MODE Eight patterns per project (A–H). Switch live; the change waits for the bar end. Then chain them into a song with repeats per section, looped or played 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. 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. KIT SHARING One .gskit file holds a project — samples, settings, effects, patterns, song. Import and Export to Files are free; sharing 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.

Pitch + jitter, spray + stereo spread, four window shapes, an ADSR cloud envelope, Freeze for infinite sustain. 128 grains per voice. 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. TRACKS shows every track in one grid; tracks 9–16 need Pro. INT SEQ lets MIDI alone play the pads. SAMPLE EDITOR Waveform view — drag the grain region, trim playback range, loop, reverse, normalize per pad. LINEAR or GRAN preview. Trim works in the plugin too. EFFECTS Per-pad AND master bus. Reverb, Delay, Distortion, EQ, Compressor, Chorus, Filter — up to 8 per chain. Hand-tuned presets; save your own in the app. 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. Background Audio plays on in other apps. The plugin routes MIDI in through the host and emits MIDI out for pad taps.

Read full description

A tape-deck-inspired looper that puts any sound on repeat – to settle someone to sleep, or to start your next song. No setup, no fuss, nothing to learn. Built for creatives and tired people alike. Open the app, press record, and ten seconds later you're up and running. But underneath, it's a real instrument – a real tool. LOOP MODE Some features require Studio. - Trim your loop on a draggable waveform, with visible, adjustable crossfade regions as the tape spins - Tune the pitch, shift the speed, or flip playback in reverse. Three controls for finding sounds you didn't expect - Drop in any audio file – a song, a sample, a voice memo – and shape it with the same tools - High-pass and low-pass EQ filters that snap to useful presets – or slide anywhere you want them - Powerful on-device denoise that reduces unwanted background noise – fans, traffic, or whatever is humming in the room – all without sending your audio anywhere - Studio-quality reverb, delay and tape-style saturation, each with presets that turn even the smallest sound into something with weight and atmosphere - Save a loop to a slot and find it where you left it, two hours or two months later NOISE MODE, DONE DIFFERENTLY Every sound in Noise Mode is original. Some features require Studio. Three categories: - 5 synthetic colors, each generated and tuned, live, in a real audio engine running on your phone - 9 field recordings captured on location with some of the world's quietest microphones – wind in an ancient forest canopy, the comforting crackle of a fire pit, the warm sonic embrace of a road trip, the waves lapping next to a Hawaiian lanai at night, and more – each held to AAA audio standards in capture and post-production. - Nocturne, a 45-minute original composition that loops seamlessly. Written to settle a newborn – and now, anyone who listens. Layer it under any synthetic color or field recording for a soundscape mix that's entirely yours. These sound good out of your phone speaker. Out of headphones, they sound extraordinary. TAKE IT WITH YOU Somnideck doesn't stop at the app's edge. - You're only ever five taps away from turning your latest masterpiece – be it the old-timey horn on your bike, or your child's bubbly laugh, into a custom ringtone you can keep and use forever. And Somnideck automatically boosts it as loud as it can be, so it stands the best chance of cutting through from your pocket. - For creatives: Export any loop as a seamless WAV with the crossfade baked into the audio, so the loop-point is invisible the moment it lands in Logic Pro, Cubase, Ableton, or GarageBand. Normally a complex process in expensive desktop software – Somnideck does it in a handful of taps. STUDIO Studio gives you the full audio creation suite – all 9 field recordings, Nocturne, the complete effects rack, pitch and speed, reverse playback, export, audio import, the sleep timer, and expanded loop storage. The looper, the synthetic noise generator, and one field recording are always free. Available monthly, annually, or as a one-time lifetime purchase. WHO IT'S FOR - Creatives who want a real, inspirational audio sketchpad that lives natively on their phone - Parents at 3 a.m. who need calm, fast - Anyone looking to settle, focus, or wind down at the end of the day PRIVACY Somnideck collects no data. No accounts, no third-party SDKs, no analytics, no tracking. Your recordings stay on your device, and denoise runs locally. A powerhouse that can stay shallow or go as deep as you need. Press record and you're done – or disappear into it for an hour. Both paths are first-class.
