Mark,I have several templates for my MIDI setup where the percussion maps work just fine. However, unless you have the same platform (Mac), the same version of Finale (2001) and the same MIDI equipment (Yamaha MU90R tone generator), my templates (and others' for that matter) may not work with your setup.
I would suggest that you repost either here or on the Coda online forums with specific questions about what platform and system you are using, which version of Finale, your MIDI setup and a description of what you have done that does not work. Maybe some of us can help you get your own maps working properly.
Good luck.
