I discovered that with the free version we can get full access to all the parameters!!
Here is how: Export your patch. Open the file with a decent text editor. GNU Emacs works well for example. The file has some non-ASCII characters used as separators, but the parameter names and values are in plainly readable ASCII ! All the parameter values are in floating point. With the help of the manual, one can decipher all the parameters and values. Edit it to the values you want to set, and import it back. No need to bother with downloading/installing the demo version.
Enjoy!
