Why does the note arrow appear when I am not singing?
This occurs when the music is so loud that the microphone picks it up. Increase the microphone threshold setting until the problem goes away.
What is the "microphone threshold" setting?
This causes low volume sounds to be ignored. If you find the music is playing so loud that it causes the note arrow to appear when you aren't singing, increase the threshold setting. For most microphones a setting of 8% works fine.
The built-in microphones in laptops do not work well because the audio speaker is usually extremely close to the microphone. This requires a very high threshold setting, which negatively effects the games ability to detect the note being sung.
How can I sing karaoke without the original artist's singing?
You will need to use a music file (MP3, OGG, etc) that is only an instrumental and does not have the original artist's singing. There are also some tools available that attempt to reduce the volume of the vocals in your existing music files, however they typically do not work well. Search for "vocal removal".
SingSong supports a special naming convention to make it easy to have both normal and an instrumental music files for the same song. For example, say you have these files:
When either of these MP3 files are played, they will use the same note file. The "(Kar)" part of the music file name is ignored when looking for a note file.
Why do I sometimes score when my arrow is far from the required note?
Because SingSong doesn't care what octave you sing in, the top note in the sing area is the same as the bottom note. For example, sing the note at the top of the sing area then sing a little higher, you will find that you are now singing the bottom note. Sometimes if the required note is very close to the bottom you will be able to sing the top note and still score. This happens because all difficulty settings except "Expert" don't require you to hit the required note exactly in order to score.
Why don't the lyrics scroll smoothly?
They should. Make sure you have the latest version of Java installed. Some versions of Java 5 do not scroll smoothly. Java 6 is recommended. Also check that you have the latest drivers for your video card.
