Since my first questions, I was able to install my old version (4.107) The bulk of any work I need to do is adequately handled by this program.
However I did take about 20 minutes to see what I could do with the demo on a duet like Frere Jacques
I read how to link to simultaneous lines and tried that. I kind of understand the possibilities.
When I tried to play the screen after tapping the lines, the program shut down. That kind of sucked; was that a demo limitation?
I will probably get the new upgrade as soon as I am confident about what I can do. Thanks for the reminder; I will probably try again this week.
