via this auction "The CZ-3000 has 16 oscillators, making for sixteen voices, and each of the oscillators in a two-oscillator patch can be independently programmed. The keyboard also utilizes key-splitting (where half of the keyboard plays one sound and the other half plays a different sound). All the preceding CZ synths before it had only 49 keys, and the 3000 is adorned with 61 keys. The CZ-3000 was also one of the first models to have both a pitch wheel and a modulation wheel."
