Hello
If anyone is interested in giving feedback:
The Centre Iannis Xenakis has just published UPISketch, a new software that can run on iPhones or iPads from iOS 9.3, and under OSX.
UPISketch-iOS version is available for free on the Apple Store.
Its purpose is the following:
UPISketch is a sound composition tool, which is based on drawing: the user can sketch and design sound gestures, from existing sounds, by redefining their melodic contour, as in the case of a conventional score. Pitches are, nevertheless, drawn directly at specific time points, without requiring any knowledge of solfege. UPISketch is intended to be simple and intuitive.
