Howdy! This is my first rack; have been adding modules as I learn more about this stuff... I'd like to be making generative music, both ambient and percussive, but I'm still getting the hang of it. Anyone have any suggestions of how I can patch this sucker up to make some basic generative music, or what modules I should add? Thanks!!

Since I'm a beginner at Eurorack, I can't judge if your rack is good for generative ambient music or not.
But I have a pretty small rack myself, and when I try to patch something generative, the Maths - Plaits - Marbles combination is fantastic. So I can really recommend you to buy Marbles from Mutable Instruments.
Good Luck!
