Exquisite Traditional Organ Sounds

The AT-SL Series offers a rich variety of stunning jazz organ, pipe organ, and especially theater organ sounds that are better and more powerful than ever. There is also a footage sound source feature that lets you change the “pipe footage” right on the console. Use the Digital Harmonics bar function on the touch screen to freely adjust the drawbar levels and volume of each footage, for an expanded number of sound combinations. In addition, you can choose from a range of highly customizable organ effects such as Reverb, Rotary, Sustain, and more. This is the way an organ should sound!

Hundreds of Voices for World Music

In addition to fabulous organ sound, the AT-SL Series also offers hundreds of high-quality, realistic instrument voices from around the world and across the centuries. There are many more strings, accordion, and choir variations, as well as exciting new traditional instrument sounds, such as Chinese Er Hu, to expand your musical expression. Of course, you can combine these voices with organ sounds to create an almost limitless repertoire of performance options.

More Active Expression Tones

The upgraded Active Expression function now has even more instrument voices to add a rich, expressive touch to your performance. You can increase the volume while adding a varied selection of instrument sounds to your playing — such as the unique textures of brass, the mood and movement of strings, or the subtle harmonies of layered organ sounds. Get ready for rousing organ-playing fun!

Enhanced Manual Percussion

Manual Percussion allows you to play percussion effects on the lowest 15 notes of the lower manual. These 15 notes let you accent or fill in percussive patterns in real time during your performance, while to the right of these notes the lower manual plays using normal registrations. There are 14 percussion sets to choose from.

Outstanding Piano Performance

Each model in the AT-SL Series has an extended 76-note lower manual and incredible stereo-sampled grand piano sounds, for authentic piano performance. There is also a damper pedal that provides the same effect and expression as an acoustic piano. The lower manual has a Split function too, in case you want to add different instrument sounds to your piano playing.

Powerful Speakers and Sound System

All AT-SL Series sounds are delivered with awesome power and resonance through multiple full-range speakers. A mighty 30 cm woofer gives you truly thunderous bass. Models with a woofer also feature the RSS (Roland Sound Space) Reverb audio enhancement system, which produces a room-filling, cathedral-like ambience.

Expanded Realistic Rhythm Section

One of the greatest features on the AT-SL Series is the wide range of rhythms and musical genres it puts at your fingertips. The greatly expanded built-in rhythm section is sorted into categories, and provides numerous rhythms for each genre or style. Best of all, the rhythms incorporate actual drum and percussion phrases recorded by professional drummers, so the nuance, timing and stress are all astonishingly alive and real.

Instant Expressiveness: Style Orchestrator

The Style Orchestrator buttons let you instantly change the style of the automatic accompaniment to one of four arrangement variations. From simple to elaborate, these arrangements add an exciting new level of real-time expression to your performance.

Edit the Rhythm with Rhythm Customize

The new Rhythm Customize feature lets you edit many of the internal rhythm patterns. You can change the drum voice, add a cymbal to the beat, adjust the timing, and make other edits to create your own unique rhythm patterns. Use the onboard floppy disk drive to save your original pattern for use on any Atelier organ.

Convenient Rhythm Search Function

With the Rhythm Search function, finding the right rhythm is a breeze. You can search using your choice of name, beat, tempo, genre or group to quickly select the ideal rhythm for the style of music you are playing.

Music Assistant with Search Feature

The new and enhanced Music Assistant, now with an easy-to-use search feature, puts more performance options in your hands. From a vast collection of the world’s best-loved songs, simply select the keyword that most closely suggests the character of the song you want to play — the Music Assistant instantly selects the optimum rhythm pattern, voice for the melody, and other panel settings. With hundreds and hundreds of Music Assistant presets, you’ll never run out of things to play.

Large Color LCD Touch Screen

The AT-SL Series’ large, full-color LCD touch screen makes playing the organ more effortless and enjoyable than ever before. The simpler screen layout and new color scheme let you perform the same operations with fewer steps, making it easier to select instrument voices for your performance, to access and control rhythm, reverb, split point, and other panel settings onscreen, and to switch to the notation display at the touch of a finger. You can also jump smoothly between Upper, Lower, and Pedal tone edit screens. Virtually every onboard function can be accessed and adjusted using the touch screen, for a single point of control. It’s easy, intuitive, and fun.

More Onscreen Features

With the simplified, color-coded LCD touch screen, the Composer, Track Mute, and other functions are easier to use. You can play along with commercially available or downloaded Standard MIDI Files and save the results, or mute a specific voice or part right on the screen, and play the solo part yourself. The series also features Roland’s famous DigiScore, which lets you display the notation of Standard MIDI Files or your own recorded songs onscreen. It’s loads of fun.

Quick Registration for Professional Sound

The Quick Registration feature lets you effortlessly select from an extensive library of registration presets created by world-renowned professional organists that cover a wide range of genres. The Quick Registrations can also be used for getting hints on how to select and layer sounds when creating your own registrations. Watch how quickly your repertoire grows.

Compatible with Any Atelier Organ

The built-in floppy disk drive lets you exchange data with other AT-Series models. You can immediately call up registrations, performance data, and music files created on any Atelier organ, or use commercially available or downloaded SMF data.
