Music content transformations tool

This tool combines music descriptions, signal processing tools (time-stretch and pitch transposition), and high-level control structures in order to change the musical content.

The tool can be included in audio editors and multitracking systems in order to achieve in real time, transformation of original recording according two dimensions: pitch and time. As long as using the usual control parameters for this type of signal processing devices, other higher-level (i.e. "semantic") controls have been incorporated.

This means, for example, that the length of an audio segment can be changed by dragging a graphical handle in order to make it fit a new temporal slot. Melodic changes (i.e. adding or deleting notes, changing tonality, etc.) can be achieved also with high-level controls.
