I've need a midi cable that goes from my joyport to 2 regular 5 pin midi connectors for the midi in/out ports on my guitar amp. I cut a regular 5 pin midi cord in half and whoa, two wires wrapped with a ground. I assumed there'd be 5 wires. 1 send and 1 return? What's up with the ground, does the cord I cut off my old joystick (15 wires) use one wire for ground? I planned to hit and miss the connections till I got a signal from pc to amp (or amp to pc) but the ground connection has me nervous. Anybody understand these cords? I went to Radio Shack and called every pc store in my tiny little southern town but they didn't carry anything. Please, please, please help me! I need this to update my amps software and fix some bugs. It will also allow me to store and move my user patches as well as upload some I found on the net. Thanks for your help. Getting pretty desperate here.
