Trying to isolate the source of a problem in the a MusicXML file, I wanted to use the
<?ignore … ?>
tag to comment out a large chunk of the file. In Dorico this produced the message
FATAL ERROR - internal error: Huge input lookup.
How big a chunk of data can you exclude that way?
Note, the error occurred excluding about 21 Mbytes of uncompressed MusicXML - this is a big project. But 21 Mb isn’t “big” for general file-handling. The complete uncompressed MusicXML file is about 230 Mb and working with that in a text editor is no problem!
