MusicTrainerProf User Guide V1.0
1. Overview
The main use-case for “MusicTrainerProf” is to repeat specific sections of a movie or audio-file.
I (as a guitar-player in a live-band) personally need that for learning specific parts of a guitar-song.

2.5. Settings- dialog
A technical restriction for apple-devices leads to the situation, that video-files from the video-library must be copied into an App-folder.
I call that “Cache-directory”. If a video-file was already copied into that cache-area, the next access is using that “Cache-directory”. With the settings-dialog, the size of this caching-area can be seen – and it can be deleted.
2.6. Help- dialog
The help-dialog shows this user-guide-document inside the App.
