Error in the parsing of config file

[Pablo-Arias]

Hi there,

I'm trying to run the cleese example shown in the tutorial—the one that transform the pitch of "really". I'm using the code provided in the tutorial. As well as the same configuration file used in the tutorial. Code is below. It seems that there is a problem in that configuration file, because the config file is missing a "main" element. I feel it's about the way the config file is being parssed, which tries to access "main" but in the tutorial only "pitch" is specified?

Thank you! Pablo
