The Casio HZ-600 is the “professional” version of the HT series keyboard synthesizers.
“Checking out the basic features of the Casio HZ-600 synthesizer. All keys and buttons work properly. MIDI IN and OUT also work as demonstrated along with Roland Fantom X6. A little bit of reverb added to the Casio with help of the X6.”
