Superb built-in sound sets, sourced from world-famous pipe, theater, and jazz organs.

AT-100 has harmonic bars, which provide instant access to a full palette of distinctive organ sounds. From 16-foot to 1-foot, different pipe lengths producing different pitches can be used in combination. Each foot length can be adjusted while playing as well.

The AT-100 has a lower waterfall-style keyboard, which is ideal for glissando and other expressive organ-playing techniques. In addition to 61 onboard key, the AT-100 provides a damper pedal for proper piano playing. Furthermore, the lower keyboard can be split into separate zones. Different instrument sounds can be assigned to up to three lower keyboard zones. This split function makes the lower keyboard equivalent to multiple keyboards!

Strings, brass, and guitar — a wealth of superb musical-instrument samples are built in. True-to-life jazz -scat vocals and choir samples are also included.

Built-in Active Expression capabilities allow you to use the expression pedal to accent what you play. And, right down to the strength of bowing, you can make instruments such as violins really come to life. Active Expression lets you play more instruments with more feeling and authenticity.

The design of every instrument in AT-100 is faithful to the way traditional organs are played. The concept is to give you the same freedom, comfort, and familiarity while layering sounds and effects as you play in real time.

Swing, country, bossa nova.... With AT-100 you can play along with organic rhythms from around the world, recorded by professional drummers. The Arranger feature (automatic accompaniment) allows you to trigger rhythmic patterns from the lower keyboard, and giving you a taste of what it's like to play along with pro musicians.
