I'm creating a software synthesizer and I want to add musical tunings, mostly those like you can find in keyboards from Roland etc.
Now I don't have them in my mind, and I wish to add at least 5 to 10 interesting ones like the Roland keyboards do. I looked up the Scala archive for .scl files and found 17 tunings that looked good to me, the well known ones like Werckmeister and those that are available on Wikipedia.
The way I want to add them is just like the keyboards, hardcoded, not via .scl format, because I haven't got an .scl parser in my preferred programming language, and more so I have no idea how to make it look good when someone were to browse through thousands of .scl files. I want to preselect the important ones.
I asked people from the Huygens Fokker website whether it's okay to copy a substantial amount of scales into something, but I got no reply.
So, is there a collection of tunings that is public domain and I could use it? I thought an old book maybe. I looked into a book from Werckmeister and I'm struggling to read it.
A CC-BY-SA license as Wikipedia text is would be okay too, but also problematic, because it's share-alike. And compared to how easy .scl files are, I have problems to read the scale tables there, too.
