can someone confirm what is required to add midi to a set of 13 note pedals? as I have read, I believe thet the following is required. Core unit DIN unit MIDIO128 Has there been any recent changes, if I am reading corectly, I have 128 inputs available. I would think that max 32 would be required for this. is there any "all in 1 DIY solution" on a smaller scale? thx chris
