I have put together a package of high quality source files for making charts.
I use Microsoft Windows and MS Paint with "Transparency" turned on.
Most any basic graphics editor program in any OS will work.
I use the copy/paste commands CTRL+C and CTRL+V to import notation elements into the staff.
You can make charts in one of two ways.
In the graphics editor import the template file into the current project and use Copy/Paste commands.
Open two instances of the program. One for source objects and one for the current project and Copy/Paste between them.
Download for quality source files.
Open with 7zip. www.7-zip.org
To contribute charts to this site you can email them to me. Please make sure they are not under any copyright violation.
