DJMAX-style keysounds: the notes ARE the melody. Hit them to play it, miss them and that part of the song stays silent. Empty-lane taps jam along in key.
LOCAL FILE ANALYZER
Analyze any audio file (.mp3, .ogg, .wav, .flac) directly from your device. Decodes, analyzes, and generates the beatmap 100% locally with zero server upload.
WHAT IS THIS?
Deterministic algorithmic audio synthesizer. The generator compiles the track directly in your browser's audio engine using a seed. Two players with the same seed will hear the exact same song and play the exact same synced notes on the multiplayer relay.

BACKGROUND VIDEO
Plays the beatmap's video behind the notes when available (osu! & StepMania). Dimmed so notes stay readable.

HOW TO PLAY
MENUS:
Navigate with a controller D-pad or arrow keys. A/Enter selects, B/Esc goes back, LB/RB switch playlist tabs.
STANDARD MODE:
Tap the lanes at the bottom of the screen when notes reach the judgment line. Supports multi-touch chords. On desktop, use keys SDKL.
SYNTH MODE:
Drag left/right touch indicators (cyan/pink) to match the continuous neon ribbons. Perfect hits depend on matching the target circle precisely.
SABRE MODE:
Swipe the oncoming blocks in the correct direction (arrows). Left lane blocks are cyan, right lane blocks are pink. Slashes must match the block color and swipe direction!
OSU MODE:
Click or tap each circle the instant its shrinking approach ring lines up. Hold and follow sliders along their path, and spin spinners by circling the centre. Mouse or touch only — no controller. Use the OSU! search source for real beatmaps, or play any YTM song with an auto-generated map.
PROGRESS BAR:
The song's progress is integrated into the judgment line (Standard Mode) or the central progress circle (Synth/Sabre Mode).
