ONE.

A song is a place you can stay.

Press Play song to hear the complete arrangement. There is no online service, sound download, or preset launcher.

Compose

The six Feel controls reshape unlocked material. Compose song rebuilds from the visible seed. Shuffle the seed for a new beginning. Variate makes a related version. Every change can be undone.

Arrange

Select a section to edit its length, energy, four-bar harmonic progression and players. Double-click a section to play from there. Duplicate, reorder or add sections. Section loop repeats the selection, not the whole song.

Edit

Select a player, then draw notes on the grid. Drag a note to move it; drag its right edge to change its length. Right-click or Delete erases it. Drum cells cycle off → ghost → normal → accent. Shift-click selects a drum cell without cycling it.

Editing automatically protects that part in that section. Unlock Protect edits to let the composer replace it. The player lock keeps that role across every section. Changing key transposes even protected notes; changing scale preserves their literal pitches.

Patch

The rack follows the selected player. Click an output socket, then a compatible input. Reconnecting the same pair removes it. Audio only routes forward; CV connects only to implemented targets. Echo and Space are shared rooms, with independent sends per player. ADSR always gates voices, including bypass paths.

Perform

Use the on-screen keyboard or A W S E D F T G Y H U J K. Z / X changes octave; Space starts or pauses; Escape clears voices and effects. The expression pad controls tone and space. Sound memories morph from the value actually being heard.

Keep it

Save downloads an editable JSON session. WAV bounces the complete song, or the selected section when Section loop is enabled. MIDI exports separate role tracks, tempo and section markers; another synth will sound different. Record captures live playing and gestures.

Audio starts after your click. Hardware MIDI depends on browser permission and support. Keep the page visible: ONE pauses when hidden to avoid a burst of late notes. Local recovery is best-effort; a downloaded session is your durable copy.

Headphones recommended. Start at a comfortable volume. Ctrl / Cmd Z undo · Shift Z redo · Esc panic
