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
It sure is confusing, but actually also really simple. ;)
It is simple because: Everything in Pd is just a number. (1) So you can use the number you get from ctlin or any other object to do with it whatever you want.
It's confusing, because the problem is not, how to get at that number, but how to built a chorus effect inside Pd. So ask yourself: What kind of chorus effect do I want to control, and how do I get this chorus effect into Pd? If it has reached Pd finally, it will accept a number almost as a natural consequence.
So you should first find an example of effects in Pd. Take a look at G08.reverb.pd in the audio examples. You'll see a feedback control number for the reverb. You can connect this number to ctlin. ctlin will go from 0-127, so you might want to scale the controller to only have a range of 0-100 by dividing it by 127 and multiplying it with 100. Now you'll control the reverb effect by your faders. It *is* simple, isn't it?
(1) or a "symbol", which is a word, or a list, which is several words or numbers, or an audio signal, which is a lot of numbers, but that's about all you'll ever need.
