Yamaha Reface keyboards are designed around the practical needs of contemporary musicians. The name of the series, "reface," is a conflation of the idea of reimagining and the legacy of Yamahas many groundbreaking keyboard instrument interfaces. Among the innovations that is hearkens back to are the legendary Yamaha Combo Organ, DX7 and CS5 keyboards. This is the reface CP, which has as one of its chief orientations the thrilling electrified string pianos from the CP80. The reface series is small. Incredibly small. But unlike miniature keyboard instruments of the past, the reface touch is satisfying and expressive, and the sound is nothing short of spectacular. The reface family of keyboards features built-in speakers and is battery operable so you can create on the go. An aux line in allows you to play along with MP3 players or whatever other audio device you wish to use. Add MIDI and USB connectivity, and the prefaces capacity to interface with external devices is vast. Reface CP puts a van full of iconic 70s stage keyboards and vintage effects into a portable retro-styled package without sacrificing sound, playability or polyphony. Choose Tine, Reed, Clavi, Toy or classic Yamaha CP80 electric grand piano, then, enhance your sound using the built-in drive, modulation, delay and reverb effects.
