Hayden Duet System Concertina

Hayden Duet System Concertina is an easy-to-play concertina for both iPhone and iPad. The Hayden system duet concertina layout is very easy to learn to play, with the notes in scale order. The iPad version is based on the full 53-button R. Morse Beaumont with the addition of an extra D# on the LHS. This makes it possible to play all of the commonly available Hayden concertina variations on the app. IMPORTANT: On the iPad version, since you may want to play chords with four or more fingers on the screen at the same time, before playing, disable "Multitasking Gestures" on your iPad (in the Settings app, under the General section, turn the Multitasking Gestures switch to the off position). How to Play the iPhone Version: On the iPhone version, the left side is one octave below the right side. Scales walk from the left and right edges towards the center. On the iPhone version, two of the most common layout options are provided: mirror image and inverted. To play, simply press the buttons. You may also slide your fingers between the buttons. Multiple buttons may be pressed at the same time to play chords. Touch the '?' button to cycle through the following layouts: Mirror image with labels Mirror image no labels Inverted with labels Inverted no labels Touch the "i" to bring up the settings page where you may transpose the pitch up or down up to one octave in semitone increments. Touch the number to the right of the transpose slider to reset the transpose to zero. When transposed, the note labels do not change, just the pitch produced.
