110MB of Sounds

The S90's wave ROM hosts an extensive voice libraries. Here you'll find good piano sounds , including a new grand piano voice featuring three layers of stereo samples that switch dynamically according to how hard you strike the keys.
Plus there's an exhaustive selection of sounds from the MOTIF music workstation, including many of its popular electric pianos, strings, brasses, 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.

Advanced Master MIDI Control Functions

Not just a synthesizer, the S90 also makes a 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.

88-Note Keyboard with Piano Touch

The S90 uses the same Balanced Hammer Effect (BH) keyboard as the MOTIF 8. Based on the Graded Hammer Effect keyboard found in Yamaha's digital pianos, this weighted-action keyboard provides smooth and realistic piano touch, because it features a 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.

USB-MIDI Interface

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.

SmartMedia Playback Sequencer

The S90's playback sequencer lets you play back standard MIDI files (format 0) directly from a SmartMedia card. You can 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 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.

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 and realtime control over part volumes, filter cutoff, effects, EQ and other frequently used parameters. And with the S90's Category Search function, pressing a button is all it takes to find the sound you're looking for.

Interactive Arpeggiator

The S90's realtime performance arpeggiator packs a wide range of patterns and styles. 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.

Plug in to the Modular Synthesis Plug-in System

With three expansion slots for Modular Synthesis 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 ready selection of new sounds the moment you install a plug-in board.
