What Is Load Catalog CSV?

Most users do not need to use it. It does not add songs, provide karaoke files, provide downloads, or provide music licensing.
External Display Help
KaraokeHost is designed to support an external lyrics display for TV or projector use.
External display behavior depends on your Mac, display settings, adapters, HDMI cables, splitters, TV, projector, and connected hardware.
Common Troubleshooting Steps
If the external display does not appear correctly
- Confirm the TV or projector is connected and powered on.
- Check your Mac’s display settings.
- Confirm your HDMI adapter, cable, or splitter is working.
- Use KaraokeHost’s display reset option if the display window is misplaced or appears black.
If a song does not appear correctly
- Confirm the file type is supported.
- For MP3/CDG songs, make sure the MP3 and CDG files are a matching pair.
- For ZIP files, make sure the ZIP contains matching MP3 and CDG files.
- Try another file to determine whether the issue is file-specific.
If key change or tempo control does not behave as expected
Key change and tempo control are available for MP3/CDG, ZIP/CDG, and MP4 karaoke songs. If the setting does not seem to apply correctly, stop playback, confirm the song type, adjust the key or tempo again, and try playing the song from the queue.
Key change and tempo control are available for MP3/CDG,ZIP/CDG and MP4 karaoke videos in KaraokeHost.
