I'll try the matlab approach, but i'm afraid of having issues regarding the application response speed. Based on your suggestion, i'll look for some Pure Data integration to achieve this too... Thanks!

I can connect my guitar to my computer and use some effects application, but now I would like to implement my own Wah Wah Guitar effect in C#. And other effects later, but this is the most important by now. Does anyone have any suggestion about a library I could use, or something? I pretend to use a slider as handler of the effect. As "C#" is the name of a guitar note too, have been quite hard to find something related to this development. Most searches just brings lyrics and tabs! :doh: Thanks!
