I've been asked to create a simple version of a leslie rotating speaker for college, Ive never used pure data before so the mathematics of it is proving difficult. I have an auto panner and chorus working but I need a tremolo attached to run along side the auto panner at the same speed. Any advice on how to do this or addition help making it sound more like a leslie would be greatly appreciated. Please keep it as simple as possible I'm only a beginner, thanks.
