About Symphowave

Symphowave, LLC is an independent software company registered in Florida, USA.

We're not a platform, a label, or a music library. We make the software that sits between a host and a good night — the unglamorous layer that has to just work while a room full of people waits for the next song.

  • Built for the booth

    Our software is shaped around how a show actually runs, not how it looks in a demo. Every feature earns its place on a live gig.

  • Buy it once

    One-time pricing, no subscription, no per-show fee. You bought it, you own it, and it keeps working.

  • Independent

    We're self-funded and answer to the people who use our software. Ship it right, support it properly, keep it honest.
