OPAS Classic – the original and best-selling orchestra management software in the world.

OPAS Classic is indeed a classic. With a 20-year history spanning over 230 clients in 27 countries, this Windows Desktop version of OPAS has established the winning combination of price, performance, security and features.

OPAS Classic continues to be a feature-rich, stable option to manage your orchestra. It runs on Windows as a stand-alone or networked application.

With the release of OPAS Next – the cloud migration of OPAS Classic – we are no longer actively selling OPAS Classic in North America. We remain committed to providing first-class support to our clients who use this application.
