Did the developer of MP3tag intend setting a limit on the number of fields in a text file for the Convert: Text file -> Tag function?
I believe I found such a limit. I constructed a format string with fifteen fields in it, including %_filename_ext%. Specifically my format string looked like this:
For one solid hour I tried to get this to parse and it wouldn't parse.
Finally I eliminated the last two fields, %involvedpeople% and %comment%.
And the routine parsed my lines exactly with what remained.
It would appear, therefore, that a line in a text file can hold up to thirteen fields. The program seems unable to parse any line having more fields than that.
I had hoped to create an all-purpose format string that could handle absolutely any information I would want to put into a tag. This includes the %involvedpeople% field, which holds entries for pianists, harpsichordists, organists, trumpeters, and other instrumental (and vocal) soloists (the conductor has his own field), as well as for arrangers. (Like the conductor, the composer has his own field.)
But it would now appear that I must remove certain fields, the entries of which would be guaranteed the same for all tracks in an album. Things like %albumartist%, %album%, and %year%, to name three. I can do that, but it would have helped to have some documentation so advising.
