Main Features of the ep-90/70
Authentic piano performances
High-quality concert grand piano sounds, and a keyboard that’s a true pleasure to play
assure an even more realistic piano-playing experience.
• Captures the brilliant resonance

The sound of a grand piano has a more brilliant timbre than that of an upright piano.
This is because the sound of a grand piano contains a greater amount of high-frequency
components. The piano sounds of the ep-90/70 reproduce this characteristic of the grand
piano.
• Reproduces the extended high-frequency response

One of the features of the acoustic piano is that for the approximately one and a half
octaves at the top of the range, there is no damper to restrict the vibration of the strings.
This allows the vibration of the string to continue whether or not the damper pedal is
pressed. Since this also allows these strings to vibrate sympathetically with other strings,
they can sometimes be heard sounding independently from the low and middle-register
strings.
The ep-90/70 faithfully simulates these characteristics of the acoustic piano.
Eight Tones for use in a wide variety of musical genres

The ep-90/70 features not only piano tones, but eight different internal tones that you
can use in a variety of musical genres.
Three Metronome sounds

The ep-90/70 provides a metronome that lets you use three different sounds. You can
easily adjust the tempo and time.
Record your own performances

The ep-90/70 makes it easy to record your own performances.

Adding Breadth to the Sound—Chorus Effect

The ep-90/70 allows you to add chorus to what you play on the keyboard.
By adding the Chorus Effect, you can give the sound greater dimension, with more
fatness and breadth. The settings of the Chorus Effect are memorized independently for
each sound.
When the power is turned on, the Chorus Effect will be applied to the “E.Piano” and
“Vibraphone” sounds. The Chorus Effect will be turned off for the other sounds.
