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.
