The Yamaha CLP 635 provides the playability of an acoustic instrument but in a more compact and digital design. The famous Yamaha CFX and Bosendorfer Imperial grand pianos are sampled to give two different dynamic and rich piano tones. The graded hammer action on the GH3X keyboard enables expressive performances. A range of 19 different voices on the CLP 635 offers the performer the ability to play in a number of different styles and the 256 note polyphony makes sure performances have that organic sound. The built in 16 track recorder has a direct USB output and allows for capturing your own compositions.
