The CasioTone 101 (CT-101) is a VERY basic analog synth from Casio circa 1981. The keyboard has 49 full-size keys and is finished in satin black painted metal, has wooden end-cheeks and a wood grain finish underneath the front of the keys. It gives your studio a good analog/vintage feel. Most sounds are very basic and fairly unusable. However, its organ tones are pretty good as well as its 'Cosmic Tone' patch, which uses two oscillators tuned an octave apart, and as the keys are held down, the sound drops an octave as oscillator 1 fades up, and oscillator 2 fades down. The CT-101 has been used by The Human League, Blondie, Vince Clark, Severed Heads, Goldie, and Moby.
