A 'keyswitch' thread below has dried up just as it was getting interesting! I hope nobody minds but I've lifted the relevant bit and started a new thread because I can't move forward without some help on this please.

And I wrote: "So it's not just me!! I'm getting the same trouble with keyswitches - the notes sound everytime I toggle from GPO and everytime I start playback and end it. I'm sure it's something to do with my set up and I'm sure someone here can provide an explanation although I drew a blank when I posted earlier on this topic. I'm using Finale 2005b and the latest GPO update on a PC."
