I have some old CD+G Karaoke discs. QMidi will play the audio tracks but no video, is there anyway I can get the video to play?

QMidi cannot currently display CDG graphics directly from CD+G disks. You need to "rip" your CD by using some third party software. This operation will extract your tracks as MP3+CDG files, which in turn will be played flawlessly by QMidi.


I just tried to put in my registration code to my new copy of QMidi and it says:  "either the code is invalid or it doesn't match the name".  Could you please help?

Be sure to use the right version of QMidi:
If your serial starts with "QMDP", download the PRO version, else download the standard version:

NB: To prevent confusion, be sure to remove the wrong version from your HD before entering the registration code.


On OS X 10.9 and later, when I go full screen on my second monitor the menu bar is always present. Any ideas on how to remove it or auto hide it?

The "solution" to this issue is to uncheck "Displays have separate Spaces" under System Preferences -> Mission Control.

MIDI Playback with the Apple DLS Synth is very quiet on Mac OS X 10.7 Lion (*)

Starting from version 2.0.4, QMidi allows you to save the DLS synth volume "compensation" (offset) in the music device setup window. You can boost the volume as needed and save your changes by clicking the "Save Preset" button:

(*) On Mountain Lion (10.8), Apple has fixed this bug.
