It's a mini version of the famous VL-1 and has some of it's features. It's monophonic, has 29 keys, 3 tones, 10 rhythms, a demo melody, a sequencer and a calculator. But it's missing the ADSR function, octave switch, volume control and output jack. It has two small piezo speakers and a rather beepy sound.

It has 7 demo songs included, but this is none of them. I made one on my own and combined it with the voice from the demo tape that was provided with the keyboard. I cheated a bit and sampled the some sounds and added delay and reverb. Because contrary to what the narrator wants us to know, the possibilities are not endless. So it wouldn't be possible to play this demo with just the CKX100 alone.

The SA-7 is identical to the SA-9 except for the colour, and more or less identical to the SA-1 which has an output jack and a diffrent demo tune. But there are a lot of Casio SA keyboards that use the same chip and share the same sounds. Some have drumpads, more demo tunes and/or a higher polyphony, a diffrent housing and sometimes less sounds.
