Casio SK-100 sampling keyboard (1987)
The SK-100 is a larger version of the famous SK-1 and SK-5 with more keys and features, including the ability to store two custom drum sequences, which can include samples. The sampler function itself has a great 8-bit / 10.113kHz lo-fi sound.
This track features vocal samples from my 2011 release "Time Over" featuring Ayika.
Casio SK-1 sampling keyboard (1985)
All sounds you hear in the track were made using the SK-1's sampler or its factory sounds
The SK-1's sampling rate is slightly lower than the SK-100 at 9.38kHz; both sound grainy and interesting.
