There are 2 parts to percussion mapping in Finale. The first is the Percussion MIDI Map. This is part of the XML files placed in your Finale MIDI Device Annotation folder. The second file is the Percussion Layout. This is part of the Percussion Library file. Both of these need to be set for the notation to look correct.
The Percussion MIDI Map is set in the upper box of the Score Manager. That column is on the far right side. If it's not visible, check the Customize View button and then check Perc MIDI Map. The Layouts are set using the Notation Style: Percussion, click settings, and then choose the correct layout.
