Hexagonal Keyboard theory and practice

I found Hex Keys very educational. Always wanted to try hexagonal keyboard. This little iphone app can really give you an idea and feeling what it is all about. Very educational.
Of course i hope for ipad vesrion as on iphone u can not really have full potential of hexagonal table.
And pls midi support so i could play with my favorite sampler/synth plugins on the computer.
Here are some info taken from a great midi controller site Axis -64 pro  which after trying this app I am considering buying ( or wait for ipad and Hex Keys pro)
