Hi,
In my _tilde_dsp function I use dsp_add to tell pd that _tilde_perform has
7 variables (my 7 inlets hopefully), and the tutorial says that you return w+(the number of variables passed plus one).
the problem is that you are not passing 7, but rather 9 _parameters_ (ref, 7 vectors, n). You need to count all values, not only the vectors.
best greetings, Thomas
