Hayden Duet System Concertina

Excellent simulation of a Hayden/Wicki duet concertina. Works very well on my iPad 2 (with iOS 8). The sound is very realistic.With the change to the updated version to make it more "realistic", but eliminating the mirrored left side option, i have lowered my rating. The current version is not nearly as exploration-friendly as the original.

This works wonderfully on the 12 inch iPad Pro. The spacing between keys feels very natural. However, I bought it because I heard you had a choice to invert the left hand (so that the same fingerings are used on right and left) and I would really like to try that before I invest $5000 in a new Concertina. (Yes I will try the iPhone version but I doubt it will feel as realistic)The next step would be to let us change the sounds to a violin or an infinite number of other instruments. Those of us who have invested many hours in learning this keyboard layout would have an entire universe opened to us. To make it more profitable you could charge for each instrument...I know I would buy them all. Please, oh pretty please?Another upgrade would be to simulate all the available Hayden Duet concertinas — the Elise, the Stagi, the Peacock, the Beaumont, the Wakker. This would be very helpful for those considering shelling out big bucks for a couple extra notes. One more idea, which might be impossible — it would be cool — and more comfortable / ergonomic — if we could play left and right simultaneously on two separate iPads. Thanks for making this, and I’m very glad I discovered it today. (For some reason my neighbors are not always happy to hear me practicing at two in the morning, so now they will get better sleep.)

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!
