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.
