Vintage digital phase distortion synthesizer from the 80's. All functions, buttons, and keys tested and working. In near perfect condition, which is amazing for its age. Purchased from original owner. Includes hard travel case which has been refoamed, original power supply with box, EZ-CZ memory expansion card, and original owner's manual. It even has posts on either side for attaching a guitar strap so you can play it like a keytar!
From manufacturer: The CZ-101 featured Casio’s original “PD sound source,” newly developed in the lead-up to Casio’s debut on the synthesizer market. PD, which stands for Phase Distortion, modified the phase angles of waveforms to generate complex overtones. Enabling tones to be produced with ease by anyone and everyone, the model opened the door for synthesizers—until then very difficult to operate and the province of only a specialized subset of users—to be enjoyed by many more people.
