🎸 MIDI guitar · Mustang & other controllersNot connected
Rock Band Mustang: connect its 5-pin MIDI Out to a USB/audio-interface MIDI In, then choose that input here. Chrome or Edge over HTTPS is recommended.
SysEx buttons: connect and grant System Exclusive permission to use D-pad, Minus, Rock Band, and Wi-Fi buttons.
Defaults: D-pad ↓ Interactive, ← Triads, ↑ Shells, → Chord melody; Minus = Smart/Capture; Rock Band = Next; Wi-Fi = reset/Home; Program − (Y) = Clear; Program + (2) = Check/Next. You can remap SysEx buttons below.
Smart mode uses incoming note releases to clear sounded notes; silent fret touches keep open strings alive without creating notes. Open strings expire after the selected grace time. Auto-complete also accepts valid chord-melody voicings. Free Play strum smoothing affects the chord name only. Channel 1 is high e. Release your previous fingering before starting the next.
Audio latency: not measured yet.
Incoming MIDI messages appear here after connecting.
