Thanks all for recommending the editor. I spent an hour or two yesterday getting some of that figured out and managed to get a couple of homemade accordion sounds that almost fit what I'm looking for. I'm a little disappointed you don't get to hand tweak the detuning on each individual reed, but I've found a setting for a 3 reed set (all 8') that comes reasonably close. It's amazing the difference in the choice of the individual reeds themselves and how they respond to the musette setting.
