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!
Ratings and Reviews
Excellent simulation of a Hayden/Wicki duet concertina. Works very well on my iPad 2 (with iOS 8). The sound is very realistic.
Great implementation of a duet Hayden concertina. Works perfectly. If only Michael Eskin would write a Wicki/Hayden Hexagonal Jammer MIDI Keyboard for the iPad!
With Family Sharing set up, up to six family members can use this app.
