The DGX-660 contemporary digital piano gives aspiring pianists a fun way to enhance their learning experience. Players of all abilities can feel what it's like to play with a band and sound like a pro. The built-in USB Audio Recorder captures your musical inspirations when you're ready to share your accomplishments.
Choose your piano, and choose where you'll play it!
Welcome to your personal "Piano Room"! The DGX-660 provides a dedicated virtual space where you can choose from a variety of pianos and acoustic settings, creating your personalized practice or performance environment. Simply select your desired piano, then choose acoustic spaces from a plain room to a club stage to a concert hall. You can even adjust the position of the virtual piano lid!
Sing along while you play!
Simply connect a microphone to the DGX-660 to either sing along with your playing or with pre-recorded karaoke song files from Yamaha Musicsoft. Hear what you sound like with everything mixed perfectly together from the built-in speakers. View the lyrics on the included score display. Three convenient presets are provided for different vocal performance situations. You can even create and save your own original microphone settings including professional reverb and chorus effects.
Go wireless with your iOS device
Optional wireless adaptors from Yamaha stream audio and MIDI to and from your iOS device with compatible music apps. The Chord Tracker app takes full advantage of this technology, allowing you to play back songs from your iOS device song library wirelessly through the DGX-660's speaker system. Chord Tracker analyzes the audio songs stored in your iOS device and then displays the chord symbols for you. It can even create an XF song file that plays back the entire song using the DGX-660's accompaniment Styles.
World Class concert grand piano sound - Pure CF Sampling
The Pure CF Sound Engine is the result of years of piano-making history combined with state-of-the-art sampling technology and piano expertise. Yamaha is the industry leader in digital piano technology, and you can hear this in the Voices that utilize the Pure CF piano sample. The sound of the renowned Yamaha CFIIIS 9' concert grand piano is faithfully reproduced, allowing for incredible dynamics and expressiveness, making the DGX-660 worthy of the Yamaha name.
Authentic piano touch, 88-note weighted GHS keyboard
The Yamaha Graded Hammer Standard (GHS) keyboard features a weighted action with 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 and strength for when the time comes to perform on an acoustic piano.
Damper Resonance
Damper Resonance digitally reproduces the sympathetic vibration between strings on acoustic pianos. Just like an acoustic piano, when the damper pedal is used in a performance, other strings add sonic color to the notes you play until the pedal is released.
Easy-to-read score and lyric display
The crystal-clear LCD can be switched to score or lyric display, showing you notation for any MIDI song that the DGX-660 is playing. Read the music for your favorite built-in songs, or follow along with songs downloaded to a USB device from Yamaha MusicSoft. Even see the score for songs you've created yourself on the DGX-660!
Live! Cool!, and Sweet! Voices
Authentic guitars, lush strings, punchy brass… the highly acclaimed Live!, Cool! and Sweet! Voices feature a unique blend of long, stereo and multi-layered samples that capture the essence of each instrument, right down to genuine resonance, expression and vibrato.
USB Audio Recording/Playback
Record performances or MIDI songs as uncompressed, CD-quality audio (WAV) to a USB flash drive using the Audio Recorder. From there, you can copy songs to your computer to make CDs, share over the Internet or transfer to your portable music player. You can also playback uncompressed WAV files stored on a USB flash drive.
Chords played simply. Sound like a pro!
Smart Chord makes you sound like a pro, even if you're just learning how to play. With a single finger on your left hand, Smart Chord will create entire chords from simple Pop triads to complex jazz 7th and 9th chords. Accompaniment Styles create the rest of your virtual band so you can get straight to playing music.
Style Recommender - Choose styles the easy way!
Style Recommender helps you find styles quickly and easily when you know how the music should feel, but don't know which style is right for the part. Simply play a few notes in the rhythm of the song you want to perform, and Style Recommender will offer a list of matching Styles to choose from.
Let your mobile music device be heard!
Use the Aux line input to connect your portable music player or even another instrument and hear the playback through the speakers of your DGX-660. The DGX-660's speaker system is powerful, clear and fine-tuned for playing back music of all types.
