Two keyboards on iPad

Two parts.
One shared moment.

Put tenor sax on one keyboard and alto sax on the other. Compare parts in a lesson, play alongside a child, or add a piano accompaniment beneath a trumpet melody.

Both keyboards share the same key size and note-label settings, so the layout stays comfortable and consistent.

Made for the love of music

A little help before rehearsal.

A spare-time project made for the love of music. No advertising, no sound packs to buy and no account to create. You read the music and play the keys; the app does not scan or import scores.
