This video looks at the Casio SK-1: Everyman’s Sampling Keyboard.
The SK-1 is a small sampling keyboard that was made by Casio in 1985. It has 32 mini 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.
