I am unclear on what you are asking here, could you describe the issue in a different manner or provide a block diagram?

Hi Frank, I'm tryng made one overdrive with high gain, based on tube screamer of Ibanez. I want use the pots control like: gain, tone, effect volume. And I'm trying to modify the cube distortion.

Well, the code doesn't compile as is, do you have a flow chart of the program, or block diagram?

hi, the code compile and run but dont change the shape of wave, i cant have a drive only a low gain crunch.
Would somehow mimic the clip of the diodes.

When I try to compile/run the code I get:

Are you running different code than posted above?
