Here is a video I did of me explaining the 4CM. I am planning a follow up video to answer all the questions that are sure to follow. I will also be doing a follow up video on how to use the MIDI on the 5150 III with the POD HD 500.
Please feel free to leave your comments, suggestions, and questions.
I don't claim to be an expert in any way. I'm just sharing my 25+ years of experience in hopes of helping people.
