Hi, Seems like you want another kind of control port, one which returns buffers of control values, just like audio ports return buffers of samples, so you can control a parameter arbitrarily.
I see a bunch of discussion around this issue in the list archives, and it seems like this solution was rejected for performance reasons. Not sure I understand the performance impact though. It doesn't seem like a good idea to hard-code particular kinds of parameter interpolation, linear or otherwise. Jake
