After struggling just to get the elicense software working, I finally have Analaog Factory installed on Mac OS X Snow Leopard; however, I can only use my mouse with the software. The keyboard is plugged directly into my iMac via USB, and it is switched on, but nothing is happening. There is no MIDI light flashing on the software. Also, I can't use the keyboard in Garageband either. This is very frustrating. I had to drive a long time to buy this thing. The manual leads me to believe there was no other step required getting the keyboard to work.
