Thanks a lot for your reply!
I gave the "Edit 2" choice a chance, as it seems mor suitable for my needs.
The problem is, I am not that familiar with compiling stuff.
I installed both cygwin and MS Visual Studio. With both I am stuck compiling flext.
If you (or others) have any hints how to this properly, I would be glad.
Or maybe there is someone out there, who allready compiled smpte~ (https://github.com/kronihias/smpte-) for Win10 and can help me with this?
Thanks a lot!
