Na sprzedaż legendarny keyboard AMSTRAD CKX100 (lata 80-te). Działa także jak klawiatura MIDI - posiada wyjście MIDI. Brak zasilacza, ale działa na sześć baterii. Działa, ale z tego co pamiętam dwa klawisze są nieme.

main voice sound is based on 2 layered static digital waveforms with independent simple envelope; with some low tones mild sample aliasing noise gets audible. The sound is stereo; the 3rd keyboard octave is panned to the center, lower notes only to the left channel and higher notes only to the right. Percussion is made from thin sounding low resolution samples.
