Hi Mark
I got 9.11 going by simply rebooting after it hung on opening a midi from Composer. The error sited beforehand was a signature error,whatever that is.

Anyway, I am a happy camper now. The GUI looks great. I can't help but marvel at the vast difference in this version compared to eight years ago, and it was darn good then. I hate to think of the years of work that has gone into your creation. It would have to be a labor of love for all involved.

After the prompting by the opening screen several times, I decided to go through your tutorial. It, in itself, is a masterpiece.

Thanks for everything.
Bernie
