Hello all! I am wondering if someone might be kind enough to explain how to connect an expression pedal to logic x. I was looking at a Moog - EP3 (or similar). I want to be able to control the wah pedal on the pedalboard. In addition to the pedal, what hardware do I need to connect it to my macbook pro? But the pedal says it comes with a TRS cable. How do I connect that to my Mac? (I have a midi keyboard M-audio keystation 49, if that helps). Thanks!!
