Casio has added two new models to its Celviano Grand Hybrid digital piano line: the GP-310 and GP-510. Both feature full-length Austrian spruce piano keys plus a true grand piano hammer mechanism, using the same materials and processes as those in C. Bechstein grand pianos. They also offer an enhanced touch response algorithm in the keys, an upgraded six-speaker Grand Acoustic System, and a new equalization option. Other notable features include the built-in song library, an improved harpsichord tone, equalization options, and an improved Concert Play mode.
Casio Celviano Grand Hybrid GP-300WE comes with three popular grand piano sounds, as well as the Natural Grand Hammer Action Keyboard. The Grand Acoustic System, combined with the multi-channel amplification system, creates an immersive sound field like that of a nine-foot concert grand. GP-300WE also features five touch sensitivity levels, 60 preset songs, 26 built-in tones, 10 user songs, Concert Play mode, Duet mode, and USB audio recording and playback. GP-300WE has a natural white wood finish and GP-300BK has all the same features in a black wood finish.
