Question: Just curious on GUID generation. Can REAPER guarantee at all times that take GUID won't repeat EVER in a project once it was generated for the take?

    It is very (very) unlikely that the same GUID would be generated twice, but it's possible that some extension or script or a bug in an in-built action could cause multiple takes to share a GUID, yes. If REAPER causes it it would be a bug, though.

    But the number generation itself relies on date/time of import or something so the number itself should never be repeated? I find interest in this kind of stuff lately - can you recommend something from SWELL to see how these things work?

    On Windows and macOS we use the system-provided library for generating GUIDs, which are unique. On Linux we use the system random number generator which should be almost always unique :)

    Now, that's a first...I usually see you writing your own implementation of anything. Awesome, thanks for the info!
