Sundar, a composer and pianist from Chennai, recently discovered that the touch screen provided by the Apple iPad works well for performing Carnatic music (South Indian Classical Music).
The app used in this performance is Animoog. This particular patch, created by Navneeth, is specific to a particular ragam or scale, which in this case is the ragam Desh. Its parameters can be tweaked to suit other ragams.
Sundar is joined by Sumesh Narayanan and Harihara Sharma.
