The use of keyswitches in GPO (specifically for bass drum and triangle) and the correct Finale 2005b notation to activate the keyswitch and subsequently get the instrument to perform has defeated me! Can anyone help please? An example Finale .mus file that contains nothing more than a few bars of bass drum and triangle, set up for GPO, would help me to see where I'm going wrong. I'm probably failing to understand the notation method which is why an example would really help. Alternatively, could anyone point me to some downloads of sample .mus and corresponding GPO files please. I've checked the Garritan site for demo files but couldn't find one for Finale that included bass drum and triangle. Thanks in anticipation.
