Piano quality only possible from YamahaThe Pure CF Sound Engine is the result of years of piano-making history combined with state-of-the-art sampling technology and expertise. Yamaha is the industry leader in digital piano technology, and you can hear this in the sound of digital pianos that utilize the Pure CF piano sample. The P-115 includes the sound of Yamaha’s renowned CFIIIS 9′ concert grand piano and is faithfully reproduced, allowing for incredible dynamics and expressiveness making Pure CF-equipped digital pianos worthy of the Yamaha name.Authentic to the touchYamaha’s GHS (Graded Hammer Standard) weighted action has heavier touch in the low end and lighter touch in the high end, just like the hammers inside an acoustic piano. Great for the aspiring pianist, practicing on the GHS action builds the proper finger technique for when the time comes to perform on an acoustic piano. Plus, the matte finish of the black keys are less slippery when playing for extended periods of time.Enhanced sound system will be music to your earsThe tweeter position has been improved in the P-­115 to be in line with the ears of the performer. Melody lines and treble passages are brighter and more expressive as a result. This new configuration ensures that the instrument sounds sparkle and come alive across the entire tonal range.Groove along in performance or practiceThe P-115 has on-board drum rhythms for practice or performance. There’s a variety of rhythm patterns to choose, from basic rock to shuffle and swing beats. Use the rhythms to add an element of fun to your practicing, or simply use them as a virtual drummer for your performances.Professional reverb makes a wide range of Voices sparkleThe P-­115 is loaded with a variety of rich Voices, from pianos to electric pianos, organs, strings, bass and more. These Voices can be enhanced by four different reverbs that you can adjust to your preference.(Recital hall) Clear reverberation, as heard in a medium-­sized hall used for piano recitals.(Concert hall) Bright, bold reverberation, as heard in a large hall where orchestras perform.(Salon) The relaxed reverberation of a large room suitable for chamber music.(Club) The crisp reverberation of a live music venue or jazz club.Show off your playing by using Styles (accompaniment)You can sound like two players all by yourself using Pianist Styles. Simply play the chords in your left hand and the Pianist Style will transform them into lush accompaniment patterns.
