I am not to familure with MIDI and I am hoping that some of you can help me understand it a little better. I have looked through the forums but I'm not sure I completly understand a few things. You have to have a midi pickup whether it be extrenal (roland) or piezo (RMC), and you have to have a midi module (Vbass).Is peizo better then external? Why? What are some good modules? What are the pros and cons to using MIDI as opposed to a multi effects unit? Can you loop with a MIDI module?
