The AT-90S is based on a traditional organ console design and is impeccably crafted from the finest American woods. The elegant dark walnut cabinet features an illuminated console panel and 25 wooden pedals, which cover a wide range of registers and free you from the common single-octave limit. An adjustable music stand is also included for easy sheet music positioning.

The AT-90S lets you fully enjoy the highquality organ sounds that form the foundation of organ music: jazz organ, pipe organ and theater organ. And unlike other Ateliers, the AT-90S is equipped with a footage sound source that combines ranks of different lengths to produce a rich, full-bodied sound—just like a real pipe organ. There’s even a Digital Harmonic Bar function that can modify the volume balance of each footage for flute-type voices.

The AT-90S features a variety of onboard effects including rotary, sustain and enhanced reverb based on Roland’s RSS (Roland SoundSpace) technology. A built in speaker provides incredibly rich sound, while Auxiliary output jacks for the RSS ambiance can be used to connect the AT-90S to an external audio system, making it possible to enjoy the rich ambience of a concert hall or cathedral right in your own home.

The AT-90S front panel is designed with a simple, straightforward button layout so that players will feel comfortable from the moment they first sit down. A large, clear color touchscreen makes it easy to access the many exciting features of this advanced, yet intuitive instrument.

In addition to organ sounds, the AT-90S features stunning pianos, strings, brass, guitars and more. New Active Expression Sounds add a highly expressive touch to your performance, from the unique fortes of brass and woodwind instruments to the subtle harmonies of layered organ sounds. Additional “Human Voice”sounds such as Gregorian Choir, Jazz Scat and Soprano Voice are also provided—complete with phrases like “Amen” and “Hallelujah.”

One of the AT-90S’ greatest features is its wide range of music styles (rhythms and performance patterns), which were produced by professional musicians from around the world. Create lush accompaniments using the Big Band or March styles, or use a simple acoustic instrumental style to complement a vocal soloist. These styles are so realistic, it feels like you’re playing with a live band! The AT-90S also has a variety of “Style Orchestrator ” functions that add diversity to the accompaniments based on the selected style.

The AT-90S can even help you select the optimum settings for your performance. 16 different accompaniment settings for each music style can be accessed simply by pressing the One Touch Program button. A helpful Music Assistant makes it easy to load optimum rhythm, tempo and tone settings by selecting keywords on the LCD panel. And with the Quick Registration function, you can enjoy brilliant registrations created by world-renowned organists.

Take your playing further with unique features like Harmony Intelligence, which creates beautiful harmonies based on left-hand chords. A floppy disk drive lets you load commercially available Standard MIDI Files (SMFs) and view song lyrics or notation right on the LCD, and lyrics can even be displayed on　an external monitor using the built-in video output.　The LCD panel also displays musical sequences for easy composition and arrangement with the onboard multitrack recorder. Features like these are only found in a genuine Roland Atelier like the AT-90S.
