Superb Organ Sounds

Like other top-grade Atelier models, the AT-15 offers a selection of exceptionally authentic, high-quality organ sounds including full organ, jazz organ, pipe organ and theater organ. You can also take advantage of a variety of orchestral voices for more enjoyment in virtually any music genre.

Realistic Rhythms

You can have even more fun performing with realistic rhythms that are actual recordings of professional drummers.

High-Quality Reverb

To further assure a rich, atmospheric organ sound, the AT-15 features a high-performance reverb. Thanks to the incredible room-filling ambience this creates, you'll think you're playing in a cathedral.

Split Function & Authentic Piano Performance

For extra performance versatility, you can use the Split function with the 61-note lower manual to select two different instrument sounds. The AT-15 also offers a damper pedal to let you perform as if you were playing an acoustic piano when using a piano voice.

Registration Buttons

The eight Registration buttons located between the upper and lower manuals enable easy operation while playing. Just press a button to quickly change voices and other panel settings, such as volume balance, solo split point and reverb, for incredible ensemble performances. You can also store registration settings on a floppy disk.

One Touch Program for Automatic Accompaniment

Fun comes easy with the AT-15. Simply select a rhythm such as Big Band, Latin, Waltz or Contemporary Pops, and press the One Touch Button. Then play just one or two notes with your left hand and Automatic Accompaniment provides accompaniments with the feel of a real band. After that, you can enjoy playing the melody with an amazing accompaniment.

Harmony Intelligence

For even more single-finger playing fun, Harmony Intelligence automatically adds beautiful harmonies to your right hand performances.

Floppy Disk Drive Flexibility

Whether you're a beginner or more proficient player, you'll enjoy the advantages the AT-15's floppy disk drive offers. You can exchange data with other AT Series models, so you can immediately use registrations and Music Files created on an Atelier organ by your teacher and friends. And you're ready to listen to or play along with the wealth of SMF (Standard MIDI Files) available from around the world.
