Get to steppin'

Modern musicians, performers, and producers need to move quickly from programming drums and samples to playing synth lines and back again. ATOM SQ was designed as a versatile and expressive MIDI pad controller for contemporary music production. Its unique design is optimized for both classic TR-style 16-step beat sequencing and drum pattern editing in Studio One or playing instruments and launching clips in Ableton Live—yet its staggered and RGB-lit 32-pad configuration is instantly familiar to anyone who’s played a controller keyboard. Advanced features let you change the keyboard scale, and a built-in arpeggiator and user-configurable touch strip make the ATOM SQ the most expressive controller you’ll ever use. In fact, it’s the best PreSonus Studio One MIDI controller available.

A complete production toolkit

Included with ATOM SQ, Studio One Artist music production software enables you to compose, record, and produce without getting distracted by the tools or hemmed in with track limitations. Easy to learn and intuitive to use, Studio One’s unique drag and drop workflow and powerful tools will let you produce faster than ever before. Also included are two carefully-curated loop libraries with custom Impact XT kits. New to version 5: Studio One Artist now lets you use your favorite third-party VST and AU plug-in effects and virtual instruments. You also now have complete support for Studio One Remote to use as a second screen or as remote Studio One control on your iPad® or Android™ tablet. And with ATOM SQ, you have the most flexible PreSonus Studio One MIDI controller available.

Ableton Live integration and more

ATOM SQ is also a unique Ableton Live controller, designed for production and live performance. You can launch clips and scenes during a performance, select devices and edit parameters, navigate tracks and scenes, control each track’s volume, panning, and send levels—plus do all your drum programming in Ableton from the ATOM SQ! Ableton Live Lite is included, so you can get to creating right away. It comes with all of Live’s essential workflows, instruments and effects—everything you need to record songs, create hands-on with your controller, take music made in your apps further and so much more.

However, wherever.

ATOM SQ is highly configurable. MCU and HUI modes plus a powerful MIDI mode let you control your favorite DAW or virtual instrument with ease. You can freely remap instrument parameters to different hardware controls, so your rotary encoders can control everything from filter cutoff to drum tuning, for the ultimate drum programming experience. You can colorize the RGB LEDs as you please to color-code your loops and samples. ATOM SQ’s LCD screen is used to display context-sensitive information, and uses a dynamic button system that changes functions depending on the task at hand. Need to add more swing to your arpeggiator or change the CC assignment of a controller? The LCD screen details functions you need, right when you need them for the job at hand.

Navigation and transport control

ATOM SQ is more than an expressive pad controller—it also lets you navigate many aspects of Studio One without a mouse and keyboard. You’ve got transport controls for stop, play, record, and a dedicated Click Track toggle. You can even zoom in and out of your timeline and navigate among your tracks, all without skipping a beat.

Wherever sound takes you...

With its unique staggered-pad layout, contextual screen design, and customization tools, ATOM SQ lets you stay in the moment of creation. Its small-footprint, USB bus-powered design means you can slip it right into your bag and produce anywhere you and your laptop might happen to go, and the complete suite of integrated software lets you start creating right out of the box. Whether you’re in the studio, on stage, or on the road, ATOM SQ gives you the freedom to create, wherever sound takes you.
