Model Expansions transform ZENOLOGY and compatible ZEN-Core hardware into entirely different instruments with their own sonic personalities, features, and preset tones. From rare and sought-after classics to the designs of tomorrow, Model Expansions give you unprecedented access to the historic and ever-evolving world of Roland synthesizers.

Legendary Sounds at
Your Fingertips

Our vintage-inspired Model Expansions capture the essence of legendary Roland instruments with astonishing realism and authenticity. With expanded polyphony and boldly modern interfaces, they deliver the unique sound and experience of the original hardware—without the expense and maintenance.

The Past Is Just the Beginning

For future Model Expansions, the possibilities go far beyond vintage. The power of the ZEN-Core Synthesis System enables exciting, never-before-heard Roland synthesizers that may—or may not—be inspired by existing hardware.
