Sinfonia Flex

Introducing Sinfonia® Flex — A New Way to Book Sinfonia

We’re excited to announce a major evolution in how productions can license Sinfonia®: Sinfonia Flex.

Since our founding in 1999, Realtime Music Solutions has been dedicated to advancing orchestra enhancement technology for musical theatre. Our flagship product, Sinfonia®, has powered hundreds of thousands of performances worldwide, across professional, educational, and community stages. Unlike a static click track, Sinfonia gives you total creative control—flexible cuts, custom keys, dynamic vamps, mixing tools, and, above all, real-time tempo and performance shaping. Nothing else comes close.

The Challenge We Wanted to Solve

Until now, every Sinfonia booking included the full instrumentation for a given orchestration. Customers could mute or unmute individual instruments to tailor Sinfonia around their live musicians—but the licensing model always required booking the entire orchestra. This ensured maximum flexibility, but it also meant a higher cost for productions that only needed a small handful of instruments.

The Solution: Sinfonia Flex

Sinfonia Flex changes that.

You can now license only the specific instruments you need—right from the booking request. We’ll build your Sinfonia configuration around those selected parts and price it at a significantly reduced rate compared to a full-orchestra booking.

This is ideal for groups who want Sinfonia’s quality and control but don’t need the entire orchestration. For example:

• Maybe you only need the specialty colors from Reed 4.

• Maybe you need Reed 4 plus more violins to fill out the string section.

• Maybe you have a nearly complete pit and just need Sinfonia to support a couple of missing chairs.

There are countless combinations where Sinfonia Flex delivers exactly what you need—no more, no less.

Designed for Real-World Use

Selective booking introduces new creative and technical considerations (e.g., what if your chosen Sinfonia Flex instruments are tacet for long stretches?). To address this, we’ve added new tools and features that make it easy to shape the show around your specific ensemble and performance conditions. Sinfonia Flex isn’t just a new pricing model—it’s a thoughtfully designed workflow.

Pricing & Next Steps

Pricing varies based on the type of production and selected instruments, but you can count on it being a clear fraction of the cost of a full booking. We’re happy to provide quotes—and even happier to help you get started with the free trial, which lets you explore how Sinfonia Flex can support your production.

We’re here to make your show sound full and fantastic.
