Set the tempo of the score

The addkey filter adds a key designation of a Humdrum file.

Without options, the addkey tool searches the data for a !!!key: g:dor, such as for G dorian. This will be inserted as a key designation in the header, such as *g:dor using this example.

The key designation can be created/change with the -k option

To also set the !!!key: record with the input -k key designation, use -K.


Future enhancements
