We need more info from you, like which Percussion MIDI Map you are using (perhaps a custom Percussion MIDI Map?)

And which Percussion Layout are you using? (perhaps a custom Percussion Layout)

Hi Peter,

I am just using the score manager. I have edited the position of the drum kit on the stave so that the high tom is on the 4th line, the mid-tom is on the 3rd line; the low/floor tom is on the 2nd line; the snare is on the third space. I am not aware that I am using a percussion MIDI map.

Regards

… I am just using the score manager …

You probably mean that you are using the Instrument List in the ScoreManager.

You are!

It is not possible to use a Percussion Layout without a Percussion MIDI Map.

You can customize the view of the Instrument List so that the Percussion MIDI Map is shown.

Unlike a Percussion Layout, a Percussion MIDI Map is not saved (and located) inside the Finale document.

Instead, all Percussion MIDI Maps are located in a special (program-)folder from where they are available in all your Finale documents (a little similar to fonts).

You can create your own, custom Percussion MIDI Maps.

If you send someone else a Finale document that uses a special, custom Percussion MIDI Map, then you must also send the Percussion MIDI Map along with the Finale document (a little similar to fonts).

IMHO, dumb feature. There is no reason that MIDI maps should not be saved with the document. Another painful step I have to go through when changing computers

I'm not sure that's as obvious as it may seem. If one sends a file to someone with a completely different sound setup, the Map I use would be of limited use.
