These samples represent various instruments, such as pianos, strings, drums, and more, and are usually compressed for space efficiency. While acting much like a sampler in the way it produces sound, its distinguishing characteristic is that it does not record audio itself; instead, its functions focus on playing these pre-made audio samples back.
