If you have more ideas and want to implement them, you will probably find features in Jazz++ to help you. Take some time to see what additional features are listed under the different menu selections. Remember to right-click your mouse when you want to do something special with a specific note or MIDI event.
If the menu choices don't lead you to what you want to do, try the help file. You may come up with a unique idea, but most questions and issues have been raised before you and have been addressed somehow in the program. Search the help file to find how other people have handled your issues.
I hope this "How To" was helpful.
