At the moment I use the $keep() function/plugin to strip away various tags I’m not interested in.
How is it possible to use $keep() on the various “performer” tags that classical works come with? “Conductor” appears as a separate tag, but there are a number of varieties of “performer”, e.g. “performer [orchestra]”, “performer [cello]”, etc. The documentation says that these are stored as “performer:”, but this doesn’t seem to work with wildcards.
How can I keep all those performer tags?
Also, how does the $performer() function work to output this stuff? How would I, for example, output a list of all the various performers on a classical release (e.g. soloist, orchestra, guests…)?
The syntax of the $performer() function in the documentation is different from that discussed on this message board:
