Hello Maarten and the list, I have been enjoying Tapiir quite a bit, and would like to intergrate it into a performance situation alongside PD & Jack. My question is, what are the possibilities for external control of Tapiir? i.e. : can I send it messages [from PD, for example] which could either change parameters, or use a different .mtd file? If so, what kind of method or protocol would work best? Thanks! D. -- derek holzer ::: http://www.umatic.nl ---Oblique Strategy # 38: "Courage!"
