Mediabay doesn't show MIDI-Files from other software

I’ve exported some tracks from other software (Reaper, Studio One Prime) to the midi file format. Then I wanted to import those midi files per Mediabay into Cubase - but Cubase only shows those midi files that I’ve exported from Cubase itself and not the midi files from the other software.

Want went wrong?
Anyone who can help how Mediabay also displays the other midi file formats?

Thanks in advance.

You need to tell Media Bay what file locations to scan to find those files.
