What is the best interface I can buy for around $200 dollars that has a midi input/output? I originally bought the M-Audio Fast Track USB ($100) which has worked well, but I'm going to want to make my own beats so having a midi input would be ideal. (Unless I can somehow plug my keyboard into the Guitar input on the device) Please help. I only have a few more days left to return this. I've read that the Scarlett 2i2 is an amazing interface. Could I connect my Yamaha keyboard to the 2nd XLR jack?
