Since I am exploring the possibilities of the iPad, I wanted to be able to play the Hang. ThumbJam offers a very good sampled Hang instrument already – but the typical layout of the metal U.F.O. was missing. Orphion recently introduced a layout customization, and virtual Midi allows to send the signals from Orphion to ThumbJam.
Oh yes, BTW, this is my first Prezi'ntation to explain how the things work together.
I've uploaded my Hang and HandPan layouts to the Orphion Universe. It should be easy for you to pick them up.
