The details on the Magic Flute are kind of limited. It looks like this was released in 2007 and intended for musicians with disabilities. As the video shows, it can add an extra layer of control for anyone.
The iRig MIDI interface connects the Magic Flute to an iPad to control not only the included SampleTank FREE but also a world of MIDI-compatible apps such as GarageBand.
It is possible to assign breathcontoll in Sample tank but it is very limited and you need to use 2 extra apps to get the job done: MidiBridge and freewi. Maybe we get better control in the future , time will tell. So far I only could control the modulation wheel, any better results? let us know.
