Yamaha CP-20 Electric Piano Keyboard, 1977, made in Japan

Модель CP20, выпущенная в 1977 году, в основном повторяла CP30, но имела немного другой дизайн (форма корпуса очень напоминает стрингс-синтезатор SS30), клавиатуру в 61 клавишу и другой набор пресетов (два фортепиано и два клавесина). Кроме того, она отличалась отсутствием второго канала и, соответственно, имела только один выход (что делало ее практически полным аналогом электропиано Roland MP-600). При этом инструмент все равно имел внушительные габариты (1080 x 571 x 155 мм), весил лишь на 14 кг меньше, чем CP30, и стоил лишь на 500$ дешевле.

Features

For the musician on tour, the CP-20 Electronic Piano combines the qualities of touch, expression and sound variety in a very portable, rugged package.

If you’re a studio musician, the CP-20 gives you the ability to shift from one color sound to another — easily and quickly — on the same keyboard, a key- board that feels very similar to an acoustic piano.

If you’re a composer, the CP-20's wide variety of sounds can help you over- come that “one-color" tired-out sound you may now be working with. The piano’s flat top is just right for scoring.

In fact, for any keyboard musician, the CP-20's unique combination of sound and features make this a very versatile instrument.

The CP-2O is velocity sensitive, just like a traditional piano. This means that when you strike the keys harder, it gets louder (continuous loudness variation, not a stepped change). Yet the CP-20 has no strings or rods to get out of tune, no complicated action to stick or break. The CP-20 is an all electronic piano; the only moving parts in the keyboard are the keys and the reliable leaf switches they activate.

Yamaha worked closely with top performing artists during the combo keyboards' development. Their many valua- ble suggestions helped perfect the touch, the sound, the features - in fact, the whole concept — of the Yamaha Electronic Piano. Thus, the CP-20 is an instrument developed for you, the musician and artist. When you play the Yamaha CP-20 Electronic Piano, feel its responsiveness, and hear its repertoire of sounds, you will understand why Yamaha, with over nine decades of keyboard instrument experience, is the leader in contemporary keyboards.
