RNBO and Max with Raspberry Pi - 02 - Adding Pots

This video shows how to get started with RNBO and Max with Raspberry Pi. We take the delay patch built in the previous tutorial and set up some potentiometers and a button to control it, wired directly to the Raspberry Pi and interacting with the RNBO patch.
