I finally (because I'm not smart) got the sounds to work correctly in the Finale template, BUT... I have added other staves to the "score" and everytime I open this "new" template, all the drum staves have piano sounds. I find that if I open the original template (after mapping each instrument a few times a while ago) AND THEN the "new" template (not altering any instrument maps) is the only time I can get the VD sounds.
Is anyone else experiencing this? It took me a while to get the mappings correct in the Original VD Template from tapspace but it does work. So I saved that, and now I have to open this before anything else to get any other template to "sound" correct.
