Did you accidentally install all LED stripes the wrong way around and need to swap/reverse all DMX addresses in every DMX universe? Thats what I had to do.
This quick hack parses a "madrix.mpx" file in the same directory, goes though all fixtures to get the highest DMX address in each universe and then swaps the highest and lowest fixture addresses, reversing the fixture order.
The result is written to "new.mpx" in the same directory
