| Notes | 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, 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-$US100 home keyboard market of the time.
The Radio Shack version of the Casio SK-1 is called the Realistic Concertmate 500. The Casio SK-1 is the predecessor to the Casio SK-5
