Soundloom and Soundshaper dont let me aply the harmonic distortion. It says something like "data file doesnt exists" I tried to edit the parameters but always says error. Some suggestion?
Have you made a loaded a harmonics file into the first parameter?
This should be a text file with just the harmonic number and the amplitude value on each line.
You need to give it value pairs for the harmonic you want it to add and the loudness of that harmonic, something like this will add even only harmonics with decreasing loudness:
2 0.5
4 0.4
6 0.3
8 0.2
10 0.1
12 0.05
In Soundloom you can press the Make File button to make the file directly, in Soundshaper you can edit it in the black box in the process window.
There is more documentation on this here: https://www.composersdesktop.com/docs/html/cdistort.htm#HARMONIC
thanks, the default file was wrong.
