I have my pisound installed and passed tests according to getting started guide. Also had installed Pure Data per instructions and seemed fine. Now I have tried MODEP running the one-step install. I am able to bring up the MODEP Pedalboards that are provided as examples, but if I try to add an effect to an existing board, or to a new blank board, all I get is Error adding effect.
Any suggestions to solve other than restarting from scratch installing the Rasbian lite?
