The Best Features of the "S" Series
The Great Sounds of MOTIF and More!
Over the years, Yamaha S series synthesizers have set new standards for sound quality, features and value. And with the new S90 Music Synthesizer, that tradition continues. Developed to be our most feature-packed S series synth to date, the S90 inherits the best features of the S series line plus the great sounds and user interface of our award-winning MOTIF synthesizer. In addition to superb piano action, a powerful arpeggiator and 24-bit effects, the S90 gives you 110MB* of wave samples more than any other keyboard in its class. And as if that weren't enough, we generously equipped it with three expansion slots for Modular Synthesis Plug-in System boards, so you can add new and exciting synthesis possibilities according to your musical needs.

110MB of Incredible Sounds!
The S90's huge wave ROM hosts one of the most extensive voice libraries ever available in one keyboard. Here you'll find some of the best piano sounds in the world, including a brand-new grand piano voice featuring three layers of stereo samples that switch dynamically according to how hard you strike the keys, for the ultimate in piano expression. Plus there's an exhaustive selection of bread-and-butter sounds from the amazing MOTIF music workstation, including many of its popular electric piano, strings, bases, synthesizers and drum kits. And for those who want even more synthesis power, the S90 provides three expansion slots to add Modular Synthesis Plug-in System boards.
Although loaded with powerful features, the S90 is surprisingly easy to use. Its intuitive user interface, centered on a 240 x 40 dot LCD screen and rotary encoder, lets you quickly navigate through menus and edit various settings. A Function Control matrix and four physical sliders give you instant access to and realtime control over part volumes, filter cutoff, effects, EQ and other frequently used parameters. And with the S90's convenient Category Search function, pressing a button is all it takes to find the sound you're looking for.
88-Note Keyboard with Exceptional Piano Touch
The S90 uses the same Balanced Hammer Effect (BH) keyboard found in the MOTIF 8. Based on the Graded Hammer Effect keyboard found in Yamaha's best digital pianos, this weighted-action keyboard provides an exceptionally smooth and realistic piano touch yet, because it features an even balance from top to bottom, voices such as drums and synth basses will feel more responsive to your playing. And for even more performance expression, it also features aftertouch.
Advanced Master MIDI Control Functions
Not just a great synthesizer, the S90 also makes a wonderful MIDI controller. Equipped with four assignable data sliders, it provides extensive realtime control over external synthesizers. Plus four programmable keyboard zones let you create complex split and layered voice combinations using a mix of internal and external voices. Entire MIDI setups can be stored in User Performance memory and recalled at the touch of a button.
Equipped with a USB-to-MIDI interface, the S90 is ready to connect to your USB-equipped Macintosh or Windows computer without the need for any additional hardware.
The S90's realtime performance arpeggiator packs a wide range of patterns and styles, giving you musical inspiration at the flick of a switch. In addition to conventional arpeggio patterns, it's loaded with an impressive array of musical phrases, including guitar strumming, drum grooves, keyboard riffs and more. Instead of trying to clone these performances with computer-generated algorithms, the S90 uses a more musical approach: It uses MIDI data recorded by real musicians. You can even program your own patterns and layer several arpeggiated voices together in a Performance.
SmartMedia' Playback Sequencer
The S90's playback sequencer lets you play back standard MIDI files (format 0) directly from a SmartMedia card. Use this function to build up a library of up to 100 songs, any of which can be instantly called up at the touch of a button great for live performance! Chain playback is also possible. The included File Utility software makes it quick and easy to transfer MIDI files from your computer to a SmartMedia card, so you can leave your PC at home the next time you do a gig.
Connect to the Future of MIDI and Audio with mLan
Yamaha's new mLAN interface technology makes it possible to route all your digital audio and MIDI signals both input and output through a single, high-speed IEEE 1394 cable, greatly simplifying the process of connecting and configuring your digital musical equipment. Equipped with an expansion slot for optional mLAN interface boards, the S90 gives you access to this amazing music network technology.
Plug in to the Power of the Modular Synthesizer Plug-in System
With three expansion slots for Modular Synthesizer Plug-in System boards, the S90 is potentially four synthesizers in one! Offering new synthesis capabilities from FM to physical modeling as well as more polyphony, effects and multitimbral parts, these plug-in boards let you customize the S90 with the exact synthesis power you need, whenever you need it. The voice data for every plug-in board currently available is already stored in the S90's ROM, so you'll have a great selection of new sounds the moment you install a plug-in board.
