Magic Music Visuals

..I understand. Thank you for sharing your knowledge! I already solved the problem with Applescript, and as you suggested, outside of Magic. I wrote an applescript that searches the last line and writes it into a new txt-file, every 5 seconds until I stop the script.. voila! # Start Repeat set theCo...

..I have to read from an automatic generated and permanently growing textfile wherein only always the last line is interesting to me. The expression only needs to count the lines of my textfile and return that number.. The C++ Mathematical Expression Toolkit Library (ExprTk) is used by Magic, right?...

Plz help, greenhorn here!
Someone knows how to screen only the last line of a text-file? -is there anyone who can help me with an expression please!

Thank you!
