Arenetto
Diatonic Button Accordion
Free
Arenetto is a diatonic button accordion for iPhone and iPad, built around the way the instrument is played: one set of notes on the push, another on the pull, and several notes at once under your fingers.
Choose G-C-F, F-Bb-Eb, or E-A-D tuning. Play with 31 or 34 buttons, switch among five registers, and adjust the button spacing to your screen and playing style. Optional note labels can be shown with sharps or flats when you want a visual reference.
Arenetto is designed for landscape play and direct multitouch, so melodies and chords respond together. Your instrument settings stay out of the way while you play and are saved on your device.
