caption_attribution_description: My beloved Casio SK-1 shares this shot with its genetic relative, the Realistic Rap-Master. Radio Shack sold the Rap-Masters long after the SK-1 was out of production, but the internals are amazingly similar.
context_page_description: The Casio SK-1 is a small sampling keyboard made by Casio in 1985. It has 32 small sized piano keys, four-note polyphony, with a sampling bit depth of 8 bit PCM and a sample rate of 9.38 kHz for 1.4 seconds, a built-in microphone and line level input for sampling, and an internal speaker. It also features a small number of four-note polyphonic preset analog and digital instrument voices, and a simple additive voice.
  All voices may be shaped by 13 preset envelopes, portamento, and vibrato. It also includes a rudimentary sequence recorder, preset rhythms and chord accompaniment. The SK-1 was thus an unusually full-featured synth in the sub-US$100 home keyboard market of the time.
  The SK-1 includes one pre-arranged piece of music, the Toy Symphony, which is played when the "Demo" button is pressed.
  The Radio Shack version of the Casio SK-1 is called the Realistic Concertmate 500.
  The SK line continued throughout the late 1980s, including the SK-2, SK-5, SK-8 and 8A, SK-10, SK-60, SK-100, SK-200, and SK-2100.
