    Sorry guys. I'm still stuck on the USB - MIDI problem. That article that I read didn't help. I was trying to test my usb to midi cable with the software that it came with. I plugged the usb portion into the usb port of my compter, my computer recognized it. But I don't have anyting for MIDI. Is there any way that I can test the MIDI inputs with and oscilloscope or something.

    Testing a MIDI out is easy enough, but a MIDI in is a bit different. You need a midi signal source... be it a controller, midi instrument, drum machine etc.
    To check an output connect a 220ohm resistor in series with an LED (connected to the anode).
    Connect the free end of the resistor to pin 4 of the 5 pin DIN midi plug, and the cathode of the LED to pin 5. The LED should flash when your computer sends data to that MIDI port from your sequencer (note, controller, sysex data).
