I would like to take a Midi file and pass it through a say a Dolby Prologic II reciever and get 5 channel sound. I have found instructions on how to create a 4 channel sound, with L-R-Center-Surround channels. Is there anyway to do this? By the way, in the instructions for the 4 channel sound, it states that in order to have the surround channel, I need to take two midi channels, making one the original instrument and the other an "inverted signal" of the original. Can this be done with Noteworthy Composer or the Jazz Midi Sequencer (the programs I use to create Midi files) while still keeping it a Midi file and not converting to wav?
