Playback Level Slider, SyncPlayer Window
Adjusts the playback volume or balance of the Audio and MIDI files.
If your computer is running Windows XP, the slider controls the balance between the audio and MIDI playback volumes. As you slide it upward toward the Audio file, the Audio file's playback volume increases and the MIDI file's playback volume decreases. Conversely, as you slide it downward toward the MIDI file, the MIDI file's playback volume increases and the Audio file's playback volume decreases.
If your computer is running Windows 8, 7, or Vista, the slider controls the combined playback volume of the Audio and MIDI files together. Sliding it upward increases the total volume, while sliding it downward decreases the total volume.
