Change Your Instrument

Tap the instrument name in the Play mode toolbar — it shows the name of the currently active sound. This opens the Instrument Library, a scrollable list of every sound available to your device.

Sounds are grouped by category: Piano, Guitar, Bass, Synth, Strings, Brass, Woodwinds, Percussion, World, and FX. Tap any category to expand it. Tap a sound row to hear a short preview — the keyboard plays a short chord so you can compare textures quickly without switching context.

Tap a sound row to select it. A checkmark appears and the sound is active immediately — you can hear it on the keyboard without closing the library. The selection persists across sessions.

Tip Starter sounds (marked with a filled dot) are bundled with the app and always available offline. Downloadable sounds show a cloud icon until you download them.

Sounds with a cloud icon are available from the catalog but not yet on your device. Tap the cloud icon on any row to start the download — most sounds are between 50 and 400 MB. Downloads happen in the background; a progress ring shows on the row. You can use the app normally while it downloads.

You can add any .sf2 SoundFont file to the library — thousands of free and commercial options exist online covering orchestral instruments, vintage synths, and more. Imported sounds appear under the Imported by You section at the bottom of the library.
