This app has been updated by Apple to display the Apple Watch app icon.
Fixed sample octave offset bug introduced in the last iPhone version. Sorry about that!
Hayden Duet System Concertina is now a universal iPhone/iPad app!
The iPad version is based on the full R. Morse Beaumont model 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: 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).
Thank you to Don Taylor for the gorgeous new iPad version graphics!

You may now transpose the pitch up or down up to one octave in semitone increments on the settings page (touch the "i")
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.
