an ambient instrument for iOS. fish for music. shape its decay. leave it running.
Binary Moon is a small instrument with three voices in one. A polyphonic wavetable synth you play with your fingers. A micro-looper that captures the last few seconds of whatever you played, retroactively, so you can fish a phrase out of the air. A spatial channel that holds it all in a hall, a plate, or an echo — and freezes it if you let it.
Made for the kind of listening where you put the device down and pay attention to what stays in the room. Inspired by ambient effect pedals — a looper and a spatial channel running in parallel with the dry signal — rebuilt as a touch instrument with a Japanese editorial design language. Premium feel, low ceremony.
Eight voices. A morphable four-frame wavetable (sine → triangle → saw → square), per-octave band-limited so high notes don't alias. Unison stack with detune, classic ADSR + filter envelope, state-variable filter with all four modes, and a sixteen-routing modulation matrix with two LFOs, two ramps, two macros, and an envelope follower.
Always listening. Press capture and it grabs the last few seconds of what you played, faded smoothly at the boundaries so the wrap doesn't click. Press again and the new layer sums in additively, around the playhead so nothing snaps. Freeze locks the loop. Filter, fade, and speed knobs let the loop evolve as it plays. An always-listening looper in the ambient-pedal tradition, rethought for touch.
Three modes you switch between as moods, not as effects: hall (large reverb), plate (denser, brighter tail), and echo (variable delay with feedback-path low-pass). Freeze captures the current spatial signature and holds it indefinitely — reverb tails decay naturally, echo recirculates near-perpetually. Output stereo width and dedicated filter on the spatial channel.
Pentatonic scale, choose your key from a chromatic picker. Hold-to-play or latch mode for sustained drones. Polyphony with smart voice stealing.
Plug in a Core MIDI device and play across the whole keyboard. Hot-plug supported. CC1 → macro 1, CC2 → macro 2 by default.
Built-in mic, AirPods, USB-C audio interface — route your voice or instrument through Kage and Nami. Fish a phrase from your guitar, freeze it, layer pad melodies over it.
Five factory scenes (kumo, shizuka, yume, kaze, mori, oroshi). Save your own. Family-marked hanko stamps make the library scannable.
Lock the screen and the loop keeps playing. When the audio actually goes silent, the engine pauses itself to save battery — wakes back up the moment something plays.
A clock dial and a pitch slider sit between Kage and Nami, modulating both phases together. Sub-octave pitch shifts on the spatial tail, half-speed loops, the works.
A short loop captured in oroshi — wind through reeds, slow filter sweep, hall reverb.
