Before diving into downloads, it is crucial to understand what a "style" actually is. Unlike a standard audio backing track (MP3), a style is a MIDI-based pattern that follows the chords you play on the left side of the keyboard.
If a style doesn't make sound (only drums are playing), you are likely missing specific voices. Go into the [Mixer] and reassign the Right Hand (R1) voices to a GM (General MIDI) sound like Piano or Strings. Yamaha Psr E463 Styles Free Download -
