Too psyched! I gave a guy from a guitar store $75 for an enormous box of old MIDI stuff. And amazingly, 90% of the stuff is unopened, unused! This is exactly what I wanted, and I almost feel bad opening some of the stuff now, some of it wrapped for 25 years. But I am not a collector. Honestly, I am not much of a musician either, but this is what I like. Looks like I am going to have my Plus and MegaST set up this weekend!
