I downloaded a midi file to a "Logic" sequencing program in order to make a CD. The problem was that when we tried to transmit the file from the computer, there was no sound. This is after I connected the midi cables carefully and checked the back of the computer, made sure the "ALL PARTS" was set in the MIDI section of my keyboard for transmitting and receiving midi data from the computer, and that the volumn was up and audio cables connected!
SO, DOES ANYBODY OUT THERE HAVE ANY IDEA WHY THERE WAS NO SOUND TRANSMITTING. (when we hooked up another keyboard, that worked).

THANKS!!!!-WAITING EAGERLY FOR HELP!!!
