Tuba Bounce

Tuba Bounce is a MIDI visualizer featuring an animated B♭ tuba. Open a MIDI file or write your own score and watch, note by note, which valves go down and how the music sounds on the tuba.

WHAT YOU CAN DO

• Open MIDI files (.mid) and follow the notes falling over the keyboard.

• Watch the 4-valve tuba in action, with the full fingering chart (B0 to B♭4) and alternate fingerings.

• Compose and edit scores in bass clef, with valve numbers shown under each note.

• Listen with real tuba samples; offline, the app uses a synthesizer instead.

• Export to WAV, MIDI, JSON and PDF (sheet music).

• Save projects on your device, with autosave.

• Change playback speed and switch between light and dark themes.

PRIVACY

No sign-up, no ads, no tracking. Your projects and files stay on your device.
