I have used MusEdit for seemingly forever. I used it up through Windows 10 when I had to upgrade to Windows 11. The install on Windows 11 was quirky. It installed, but, at times, behaved erratically. That said, I have never come across another Tab product that measures up to MusEdit. Guitar Pro, Tabledit and even an oldie but goodie named, "Tabrite" have never measured up to the capabilities of Musedit. It remains my "goto" software for all musical needs. There is a program called, "Noteworthy", which is out of England and I use it interchangeably with Musedit dependent on what I'm doing.
I have been using MusEdit regularly since its inception and it it priceless. I use it for tab, chords in standard and alternate tunings, for guitar, mandolin, banjo, adding my own chords to the chord library. I run it on Windows XP, 7 and 10. Only issue is a false error saying that a file was not saved when saving over an existing file - the file is actually saved. For me Doug's software has stood the test of time. Brilliant.
