Click a card to focus it, then play with your keyboard — or just click/tap the frets directly. Everyone connected to the same relay hears everyone else play, live.
The scale section of a real yueqin recording this instrument's tone was tuned against:
Full chromatic range, real sustained notes (CC0 sfzinstruments pack) — hold a fret to sustain, release to stop.
Bonus board, click/tap only — the original 8 accented notes plus the full articulation library. Most of it doesn't have a dedicated key (the main grid above already claims most of the keyboard).
14 real recorded notes (A5–G7, natural pitches only). Hold a key to sustain, release to stop.
Real dagu (bass drum), temple blocks, snare, bangu clapper drum, naobo cymbals, gong, and rattle drum. Hold gong/naobo/rattle to let them ring, release to choke them.
