Thanks Pipeline,
It is kind of frustrating to see Mac version does not have this cross-platform feature. It is not difficult to make markers in Logic Pro X, either, but it won't be as streamlined as working in Windows environment.

Guess that reaper won't read the part markers info from the MIDI file's meta data? If there is something that can extract the meta data and convert them in to MIDI standard marker text, that would do, too.

Best,

Seeph
