Mutiple Channel Recieve On 5080? Options

[alchustriel]

I am having difficulty with all music software I have tried getting my Roland XV-5080 to recieve on all MIDI channels at once. I am running Mac OS X Panther, and have CoreAudio configured so that it send and received to the 5080 on all 16 channels. Unfortunately, when I setup a score or perform sequencing, even though I assign different channels to each staff of track, only track 1 is played. When I look at the MIDI setup screen on the 5080, it appears to allow a selection of only one MIDI channel at a time. I know that I can perform a complex setup and assign MIDI channels directly to instruments on the 5080, but there must be a way to allow program changes on all 16 channels from music software? Do I have the 5080 setup wrong? Is there something I am missing? I remember doing this in OS9 with a Sound Canvas module. There must be way. Any help if greatly appreciated.
