GRAIN
FragmentBreaks the source into grains and scatters them. Every sound in SEED starts here.

Stage 1 of 7
Transform any sound into something alive.
SEED is a procedural sound ecosystem for iPad. Load any sample, and seven processors fragment, shift, resonate and scatter it into sounds you would not have designed deliberately.
For iPad with iPadOS 18 or later. New to SEED? Read the quickstart guide (PDF, 1.2 MB).
Seven processors, one signal path.
Every sound you load travels through the same seven stages, in order. Each stage has its own engine and its own modulator, and each one can be soloed, bypassed or randomised on its own. Choose a processor to see what it does.
PITCH
Shift, stretch, formantShifts pitch, stretches time and moves formants, each on its own. It can also layer up to ten subtly spread voices.

RESONATE
Model and exciteA resonant body that the grains set ringing. Tune its frequency and decay, and decide how hard the grains excite it.

PARTIQ
Emit and evolveReleases particles of new material that live, move and fade, then passes everything on down the path.

SPECTRA
TransformReshapes the whole spectrum of what has been built so far. Hold it, smear it, shift it, tilt it or warp it.

FILTER

SPACE
PlacePuts the sound in a space, from close to far away. It is the last stage of the ecosystem before the effects.

Stage 7 of 7
Randomise with purpose
The SEED button randomises the whole ecosystem. Slight Mutate only nudges it. Lock any control you want to keep, and undo anything you don’t like.
Probability on every stage
Each processor has its own probability, so it doesn’t act on every hit. No two hits come out quite the same.
A modulator for every stage
Each processor has its own modulation, with sine, triangle, saw, square or random shapes, synced to the tempo or running free.
Then four effects, in series.
After SPACE, the sound runs through four effect slots. Put any of these processors in any slot. None of them uses feedback, so nothing turns into echoes or runaway tails.
-
PULSE
A rhythmic pump and gate with adjustable digital grit. It changes dynamics and texture without adding repeats.
-
DRIFT
Keeps pitch slightly unstable, in time with the tempo or free. Wide mode moves the left and right channels separately.
-
JOLT
Short, rolling jumps in time: backwards, forwards or at random, with no echo tail.
-
CRUSH
Drive, hard clipping or bitcrushing, all the way to complete destruction.
From first sound to finished recording.
SEED 1.1 adds starter sounds, microphone recording, sessions, MIDI and portrait mode.
Start with any sound.
Load up to 16 samples from the Files app, or tap Load Starter Sounds to begin with 14 built-in sounds. SEED cycles through them in the order you choose, including random, and plays each one forwards, backwards or in a random direction.
Record a new source.
Capture up to three minutes with the iPad’s microphone. The take becomes a sample straight away, so you can hear SEED transform the room you are sitting in.
Hold it any way you like.
SEED works in portrait and landscape, in light and dark mode, and keeps playing in the background while you use other apps.
- Record what you hear
- Record SEED’s output as a 24-bit WAV file. Play, rename, share and delete recordings in the Recordings browser, or find them in the Files app.
- Sessions
- Save your ecosystem, samples and settings as a session. Continue picks up exactly where you left off.
- Tempo
- 30 to 300 BPM, with tap tempo. Rates from four bars down to 1/32, synced to the tempo or free.
- MIDI
- Play the 16 sample slots from a keyboard or pads, trigger SEED and Slight Mutate, and start and stop from another app. See the note map.
- Undo and redo
- Step back and forward through your changes, including randomising.
- Safe output
- A volume control, a level meter and a limiter keep levels in check. PANIC silences everything at once.

Metron keeps perfect time.
A minimal, sample-accurate metronome for iPhone. Tap the ring to set your tempo, choose any time signature, and play.
-
Tap tempo
Tap the centre ring along with the music. Metron reads your taps and lines the click up with them.
-
Any time signature
Presets for 4/4, 3/4, 6/8, 7/8 and more, or any signature from 1/2 to 16/16, with an accented first beat.
-
Steady from 20 to 300 BPM
Every click is placed to the exact audio sample, so the timing never drifts.
-
Ready to practise
Keeps playing with the screen locked and the silent switch on, in light or dark mode.
For iPhone with iOS 17 or later.
