CS01

An analog synthesizer with speakers and a 32-key mini-keyboard.
This battery-powered synthesizer is equipped with a strap pin like an electric guitar so that it can also be played as a shoulder keyboard.
The tone generator is analog, but the pitch detector is digital. At first glance, it looks like a synthesizer for beginners, but it is also compatible with breath controllers for more expressive performances.
Chick Corea has even used it onstage.
