Displaying "conductor" in artist display

[simoncn]

You can set this as the suffix for $conductor. This means you need a separate format item for $conductor, as follows:
Artist.displayFormat={$artist$composer$soloists$orchestra^^^; $conductor^; ^, conductor^; }

This should do what you want as long as there is only one conductor.

Edit: To handle multiple conductors, you can do this:

Artist.displayFormat={$artist$composer$soloists$orchestra^^^; $conductor^; ^, conductor^, conductor; }
