This is the first of a set of four movies I created for Learning Modular Patrons on using the Mutable Instruments Marbles in generative patches, as part of a larger series I am writing on the subject. The first post including this movie are free for everyone to view; the other three posts and movies are for +5v level Patrons and above. That first free post is at https://www.patreon.com/posts/50069929 ; you can subscribe to the Learning Modular Patreon channel at https://patreon.com/learningmodular
