The sampler is a computer that converts sound into numbers, the zeros and ones of digital code. In its early days, the sampler was used primarily as a quote machine, a device for copying a segment of prerecorded music and replaying it on a keyboard at any pitch or tempo. But because the sound has been converted into digital data, the information can be easily rearranged. This means the source can be disguised to the point of unrecognizability, and it opens up a near-infinite realm of sound-morphing possibilities.
