The Reformer Analysis Tool is an open platform. You can share these library licenses between friends, colleagues and the Reformer Pro community. As long you as you have a valid Reformer Pro license, you can use libraries created by other users.
You will need to share both the preference files created by the Analysis Tool and the audio files used to create it to share the library with another Reformer Pro user. This is covered in the Reformer Pro manual.
You will need the rights to share/re-distribute the audio files used to create a library to share it with other users as well as full user privileges to some areas of your hard drive.
