Recently, I have been encouraging my guitar students to investigate an CS-based interactive approach to guitar performance. This has included the construction of their own DSP abstractions and the real-time extraction and mapping of various hierarchical levels of instrumental pitch data. The following tutorial patch concerns the construction of a simple ring modulator.

You can download the patch from here.

I have been toying with the idea of producing tutorials on a regularly basis, once the doctorate is completed early next year. Please send on your thoughts to info at rickygraham dot net
