I've searched their website with hope to find something, but there isn't anything available regarding your inquiry. That's why I recommend downloading the latest version which will also contain the Help manuals. Inside the 32bit or 64bit folder you will find the PDF files that will help you achieve what you need.
Make sure that you have an unpacker installed to extract the archive. The latest version of KORG KROSS Editor
is 1.1.0, therefore if you have a previous installed one, consider upgrading.
