I've got an sci six trak I bought new ages ago. Always found the interface a little funky, but fun. I learned about LFOs, oscillators and ADSR envelopes on an arp 2600. Now that I have kids, I'd like to give them the six trak and a good midi editor to play with/understand. It looks like MD may fill that need, but no idea how to implement it. I've an iPad 1 and the camera kit along with midi 1x1 tab from E-MU...now what?
