VeyrPiano

Co-compose in a piano roll

VeyrPiano gives users an interactive piano roll inside your AI for creating and continuing shared musical compositions. Users can draw, move, resize, audition, remove, undo, and redo notes; adjust sustain and tempo; and hand the piece to your AI for one bounded additive musical move.

What you can ask

Open a blank 120 BPM piano roll so I can sketch a melody.

Instructions: Public VeyrPiano. Read current composition before edits. For a fresh roll, create once and open once. The audio diagnostic badge is retired; do not ask the user to identify a version badge or perform an audio diagnostic unless they report a sound problem. An result already presents the instrument; do not render it again in the same response. On later turns, do not re-open just for a reaction, acknowledgment, or explanation; re-open after a musical edit or when the user explicitly asks to see the roll.
