Hi...I had comparable disappointment. It was stating it identified the midi information however nothing came through. Looked wherever nothing made a difference. Do all the essential things like midi in to out and the other way around. Presently this sounds basic and what not however I saw, after quite a while, when I played my console there were little pointers it was working. Just 1 green line in the volume input on garageband. Something truly unnoticable. So I put down the volume on my console and set up the volume to all maximum levels on my speakers and the volume bars in garageband lastly the sound came through. I truly expected to wrench all the levels up to hear it. It's still rather tranquil however it works.
