I'm having a number of problems with old MGU files (created by 2012 or earlier versions).

1. Text added in the lead sheet print screen (Composer, Tempo, Copyright etc) is truncated (missing first character) and sometimes duplicated.

2. Printouts of the lead sheet lack the copyright notice, although this is visible on the screen

3. Crashes with one particular file when I click on the Mute button for any instrument.


I still await a response from Support for 1. and 2., and I've recently sent the Apple crash logs and the offending MGU file for 3.

I have a large number of MGU files created with earlier versions, and it's going to be a long and laborious process to load them up in BIAB 2017 and edit the text fields (as in 1.) let alone the inconvenience of dealing with crashes.

If I had information about the file format and the way it has changed between versions, it would be worth my while to develop a conversion utility.
