Pond - Ripple Sequencer

Tap the water and watch a wave play your notes. A calm, generative MIDI sequencer with a built-in synth, also an AUv3 plugin for your favorite host.

Pond is a MIDI sequencer built on one simple idea: drop a stone in the water and let the wave play the notes.

Every cell of the pond is a note. Tap anywhere and a ripple expands from your finger; as its wave front crosses each cell, that note sounds. Where you tap, what notes you've planted, and how the waves overlap becomes the music. Tap with several fingers for several waves. Hold a finger still and you plant an emitter: a spring that keeps dripping ripples in time, on its own.

It plays better than it has any right to. Generate a fresh pond in any of nine scales and a key of your choosing, set an octave range, paint notes by hand with the floating paint bar, and let it run. Turn on wave interference and the ripples behave like real water: overlapping crests play louder, a crest meeting a trough plays softer or cancels to silence, so the dynamics emerge from the physics, and you can see them bloom in the water.

Pond has a built-in 16-voice synth, so it makes sound the moment you open it, no setup. It also speaks MIDI to everything else: pick your USB, Bluetooth, or network synths from a dropdown and Pond plays them directly, send notes to other apps, or load it as an AUv3 MIDI plugin in AUM, Logic, and Cubasis where it follows the host tempo and saves with your session.
