Seaweed Factory has released Casio SK-1 Rhythm and Tone Sample Pack, a free sample pack containing rhythms and tones of an unmodified Casio SK-1 sampling keyboard.
Though the sampling feature of this keyboard is wonderful, the lo-fi drums and tones are also pretty neat.
All samples were produced using a unmodified Casio SK-1 Sampling Keyboard. Normalization was used across multi-samples, but dynamics between notes are preserved. Some samples are labeled to indicate note or drum pattern. All eleven drum patterns are sampled at the default rhythm. The fill pattern for each rhythm is also available. Each of the eight built-in voices has been multi-sampled at octave intervals of the note C. Individual drum hits have been extracted from patterns.
This sample pack is free to use in commercial and non-commercial productions, the redistribution is prohibited.
