Main Features
●Naturally responsive 88-Key Balanced Hammer Effect keyboard (with aftertouch), drawing on our extensive
experience and expertise in piano-making.
●Wide range of dynamic and authentic voices. Use the Category Search function to quickly call up the sounds
you want, based on their instrument type.
●Half Damper function that lets you finely control the decay of the sound—and expressively recreate the
complex charactistics of acoustic instruments, especially piano and stringed instruments.
●Includes the newly developed Damper Resonance—an Insertion effect that reproduces the rich harmonics and
unique sound characteristics of an actual grand piano when using the damper pedal.
●Stretch tuning used on many Voices—the same kind of tuning as used on an actual acoustic piano.
●Arpeggio feature, which automatically plays a variety of sequenced phrases in response to the keys you play.
This function lets you easily call up various melody and rhythm patterns—over 1,700 types—providing instant
inspiration for song creation and performance.
●Versatile Multi mode lets you set up the S90 ES for playing multiple instrument parts from your sequencer
software, giving you all the sounds you need to realize complete, professional-sounding songs. Moreover, the
corresponding Multi Library lets you have the proper instruments for the selected type of music called up
instantly and automatically.
●Extensive effect processing, with Reverb (20 types), Chorus (49 types), eight separate Insertion blocks (each
having two blocks and a total 117 types), Master Effect (8 types), and a digital equalizer (3-band Part EQ and 5-
band Master EQ).
●Comprehensive real-time control with four Control Sliders—letting you adjust filter, levels, effects, EG, and more,
while you play.
●Master mode—for using the S90 ES as a master keyboard controller (with independent Zones), and for easily
reconfiguring the instrument between Voice/Performance play and Multi play in live applications.
●Remote Control—for operating your favorite sequencer software from the S90 ES.
●Three Modular Synthesis Plug-in System slots, which let you upgrade the S90 ES with a completely new
synthesizer or sound-processing engine. These Plug-in boards give you more voices, more effects, more
polyphony and more instrument parts. Plus, special Plug-in voices have already been programmed and stored
to the S90 ES, ready to be played as soon as you install the proper board.
●A full rear panel of input/output connections provides maximum interfacing flexibility. These include Assignable
Outputs, A/D Inputs, MIDI, and two USB. Moreover, an optional mLAN16E board can be installed.
●Two USB connectors—USB TO HOST for connecting to computer, and USB TO DEVICE for connecting to
storage devices, such as a hard disk drive or flash disk.
●Compatibility with Yamaha's powerful Voice Editor and Multi Part Editor software—featuring comprehensive,
intutive editing of all parameters from your computer.
