Main Features

■Main Features

❍Highly Realistic Rhythms and Automatic Accompaniment Functions

All rhythms use data from performances by professional drummers, featuring high-quality patterns with all the grooves and subtle nuance of the real thing. In addition, you can use automatic accompaniments that are perfectly matched to each rhythm to enjoy the feeling of playing with your own band in the background.

❍Developed Active Expression Sounds

For some of the sounds, moving the expression pedal will vary not only the volume but also the tone, or add other sounds. From pianissimo to fortissimo, the tonal character of the sound itself will change as you perform a crescendo, or strings may appear behind the piano, creating dynamic changes in tonality.

❍Human Voices

In addition to a full complement of organ tones, the AT-15 also features tones that express a wide range of human vocal qualities, including “Jazz Scat,” which changes according to how firmly the keys are pressed, and “Classical” tones that perfectly express that choir image.

❍Split Function

The 61-key lower manual can be split into separate sections, with each being used to play a different tone. Using the Split function lets you perform with the richness of performance expression rivalling that of three-manual and even four-manual instruments.

❍Registration Buttons

The AT-15 features eight highly visible and intuitive buttons for calling up registrations, which allow you to switch among tone and rhythm settings instantly. Furthermore, these are located between the upper and lower manuals for better access when performing in real time.

❍Harmony Intelligence

The Harmony Intelligence function automatically adds harmony to the upper keyboard sound according to the chord you play in the lower keyboard. This gives you greater tonal depth and a more powerful performance.

❍High-Quality Reverb

In addition to often-used “HALL” and “ROOM” type reverbs, the AT-15 also includes “LARGE CHURCH” and “CATHEDRAL” reverb settings, which feature extremely long reverberation times and can be used to add enormous presence to your organ performances.
