If a PDF with the same name of the audio/MIDI file ("songname.mp3" <=> "songname.pdf") is found, it is displayed in the karaoke/mirror windows. Use the "Karaoke > PDF" menu to customize the display format and access other useful commands. The same commands are available in the karaoke/mirror contextual menus.
Tip: you can easily copy and link a PDF file by dragging it on the karaoke window.
If the PDF has only one page, QMidi will automatically scroll that page during playback. If the document contains two or more pages, you will need to sync them to enable automatic page change/scroll.
You can of course do step 3 while the player is stopped. It is not necessary to synchronize all the pages at once: you can adjust the position of a page at any time by rewinding and clicking it at the right time. All actions can be undone using the"Edit > Undo" menu.
Tip: Option-Click a page to move the playhead at the corresponding time. Link a PDF file by dragging it on the karaoke window.
On Mac OS 10.7 or later, you can edit the document layout with unlimited undo support.
