Preset voices, tones, and styles refer to sounds that come with your weighted keyboard. They are often a mixture of sung notes, instrument sounds, and even everyday sounds. If you are composing a song, but want to include a sample of a drum beat or a horn melody, then a preset style will be useful. They allow you to create original content by combining different notes from different sources. You can usually record your own sounds and use them too, but the more preset options there are, the less work you’ll have to do.
