Outstanding sound and user-friendly features for organ playing fun
Expanded Performance Possibilities
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.
61 notes
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.
Damper Pedal
Ideal Features
“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.

Available Music Files
With the AT-15, you can use music files that carry any of these marks:
General MIDI
General MIDI is a set of recommendations which seeks to provide a way to go beyond the limitations of
proprietary designs, and standardize the MIDI capabilities of sound generating devices. Sound generating devices
and music files that meet the General MIDI standard bear the General MIDI logo. Music files bearing the General
MIDI logo can be played back using any General MIDI sound generating unit to produce essentially the same musical
General MIDI 2
The upwardly compatible General MIDI 2 recommendations pick up where the original General MIDI left
off, offering enhanced expressive capabilities, and even greater compatibility. Issues that were not covered by the original General MIDI recommendations, such as how sounds are to be edited, and how effects should be handled, have
now been precisely defined. Moreover, the available sounds have been expanded. General MIDI 2 compliant sound
generators are capable of reliably playing back music files that carry either the General MIDI or General MIDI 2 logo. In
some cases, the conventional form of General MIDI, which does not include the new enhancements, is referred to as
‘‘General MIDI 1’’ as a way of distinguishing it from General MIDI 2.
SMF with Lyrics
GS Format
The GS Format is Roland’s set of specifications for standardizing the performance of sound-generating
devices. In addition to including support for everything defined by General MIDI, the highly compatible GS Format
additionally offers an expanded number of sounds, provides for the editing of sounds, and spells out many details for
a wide range of extra features, including effects such as reverb and chorus. Designed with the future in mind, the GS
Format can readily include new sounds and support new hardware features when they arrive. Since it is upwardly compatible with General MIDI, Roland’s GS Format is capable of reliably playing back GM Scores equally as well as it performs GS music files (music files that have been created with the GS Format in mind). This product supports both the
General MIDI 2 and the GS Format, and can be used to play back music data carrying either of these logos.
XG lite
XG is a tone generator format of YAMAHA Corporation that defines the ways in which voices are expanded
or edited and the structure and type of effects, in addition to the General MIDI 1 specification. XGlite is a simplified version of XG tone generation format. You can play back any XG music files using an XGlite tone generator. However, keep
in mind that some music files may play back differently compared to the original files, due to the reduced set of control parameters and effects.
‘‘SMF with Lyrics’’ refers to SMFs (Standard MIDI Files) that contains lyrics. When Music Files carrying the ‘‘SMF
with Lyrics’’ logo are played back on a compatible device (one bearing the same logo), the lyrics will appear in its display.
