The Function Button Help:


This button allows you to open an audio file (WAV or MP3) and will allow you to search anywhere on your computer using the normal windows explorer.

The window alongside the open button displays the following:

  • Song/file name
  • Song length (minutes/seconds)
  • Current song position (minutes/seconds)

The song position indicator also gives you a visual indication of where you are in the song. You can slide this along to choose any position you wish.

Key Slider

This is a simple visual indication of the key relative to the original key. You can change the key by +/- 6 semitones.

Note: When you load a new song this will automatically reset to 0.

Tempo Slider

You can use the tempo slider to change the tempo and you will be able to see the difference to the original as a % or in Beats Per Minute (see below).

Original BPM/New BPM

The Original BPM window defaults to 100 Beats Per Minute for all songs – the New BPM window will indicate the difference relative to the default 100. This is adequate for most applications, as you will change the tempo whilst you are listening to the song and save the changes when it sounds right.


If you prefer to be precise with the BPM you can press the detect button. This will scan the whole song to determine the real tempo then display it in the Original BPM window. This may take a few seconds depending on the speed of your computer.
