hi, I'm a beginner on Processing, I have a few questions about this:
I'm a musician and I want that the music I'm playing live is projected as images, but I have no idea what I need to do this,  I'm still learning to program, so I really don't know which code I should use ( if someone helps me with that I would appreciate). In addition to the code, what else I need to catch music that is being played Live pass through to the program?

please someone help me!!!!

sorry for my english, I don't know it very well.
