Background: I'm a GPO Newbie (just got mine a couple of days ago, and loving it!) In this case, I'm using GPO Studio with Finale 2004.
I have a "front row" cornet staff that starts with a solo cornet on the first phrase, adds a second player in unison on the second phrase, and the whole row in unison on the third phrase. I'm using a solo trumpet for the first phrase, and I've built two seperate ensembles that play the second and third phrases VERY realistically. If these were 3 different instruments in a GM module, I could embed patch changes that would allow me to switch between the three sounds on the same staff. Is there any way to do something similar with GPO? The only way I've found so far is to do this as three seperate staves, not very print friendly.
