Im trying to understand Gen but missing proper documention so I dont understand so much.

for example Im using jit.gl.pix for trying to adjust brighness and so on and found out that you can do like this to controll the brightness etc:

though all of them seems to modify the same thing and Im just guessing so maybe something is strange

any guidance in the right direction in how to think regarding gen?

are there any list somewhere of all the parameters thats possible to use?

The param operator uses names only for directing data from the outside Max patcher into the Gen patcher. So giving the param operator different names does nothing as far as the actual processing function of the Gen patch. So if I put a message box in the Max patch with the name "Brightness" and a variable and connect it to a Gen object all the Gen object is going to do is look for a corresponding param operator that is named "Brightness" and it will send the values received from the message box in the outer patch to that named param operator.

The way to think of any Gen object is that you are essentially coding your own external. So you have to set up the appropriate logic within it and that includes the naming of parameters and how those parameters function within the object.

In other words, parameters are user defined in the context of Gen.
