I dont suppose anyone knows of any tutorials on the web to explain these thoroughly, the pd documentation doesnt talk about it really, I just dont know how to assign my general purpose controllers to adding effects or changing volume or something, at the moment they just do nothing except change the number. ie ctlin 16 will make my first controller knob on my midi keyboard change the number attached to ctlin 16 but I want to able to assign that value to a chorus effect maybe, is this possible??? cheers for any help, I know its fairly simple stuff but its just Im only startin out and Its seems confusing thanks adrian
