Sorry to say, not confused with the channel and patch numbers. In the Edirol Orchestra plugin the instrument patches for the orchestra "section" corrispond to the channel number. In other words, if I want the Brass section to play I need to go onto midi channel number 3, then I can select a subset patch from the Brass section for say, trumpet.

I thought like you at first it was a simple midi channel cross talk, but, alas no. I even tried reducing to just 1 track set to channel 0. On the plugin this should be Wind section. As soon as I pressed play the patch jumped to 2 which is the String Section (patch 5).

What is controlling the selection? It is obviously a control code at the very begining of the midi event list, but I cannot see this anywhere. It only happens at the begining. If I start the track halfway through it stays on the patch selected indication it is not midi channel dependant.

It's certainly got me completly baffled, lest of which is I can't use the plugin as I had hoped.
