Baryon Desktop is free to download and explore. A 10-day Baryon Pro trial lets you evaluate the full performance toolkit, and a paid Baryon Pro license keeps it for live use. Embedding or redistribution needs a separate Commercial/OEM license.

​
The plans

​
Baryon Desktop — Free

Download and run the app with no account. Free covers exploring the instrument and personal, non-commercial use:
  • the full real-time cymatic visualizer and core visual controls
  • live audio from a file, a microphone, or system audio
  • a starter set of presets

​
Baryon Pro trial — 10 days, included

Every install includes one 10-day Baryon Pro trial. Start it from the License panel (in the app menu) or from any Pro gate — no account, no credit card, no network connection required. While it runs, everything in Baryon Pro below is unlocked. When it ends, the app returns to Free; nothing is taken away from Listener Mode.

​
Baryon Pro license — paid

Unlocks professional, live-use capability:
  • Performer Mode with show-safe controls
  • external display / output into VJ and production tools (Syphon on macOS, Spout on Windows)
  • local OSC and MIDI parameter automation for show-control and hardware control-surface workflows
  • commercial performance rights — use Baryon as your instrument in paid shows, festivals, and client gigs
Additional routing and deeper hardware profiles are still being developed.

​
Commercial / OEM — separate

A separate license, not the Baryon Pro license, is required to embed or redistribute Baryon — shipping it inside another product, an installation, hardware, a hosted service, or a redistributed app. Contact licensing@baryon.live. This is the same boundary that governs the open engine; see the engine licensing for how the source-available license and commercial use fit together.

Free versus Pro at a glance

Commercial performance rights come with the paid license; the trial is for evaluation.

How licensing works

The Baryon Pro license is designed to stay out of your way during a show:
  • No account required. Your purchase creates an entitlement on our side; the app holds a signed, locally verifiable proof of it. Activation is a link or a token — never a login.
  • Verified locally. The app checks the signed proof on your own machine, so a network outage at a venue never blocks a performance. Offline grace is built in.
  • Online only when it helps. Connectivity is used for activation, moving your license between machines, revocation, and updates — never to run a set.
  • Subscriptions refresh, they don’t reissue. While billing is active the entitlement stays active and the app quietly refreshes its local proof. Your license is not replaced every month, and a short outage never interrupts a show.
License terms are presented at the time of purchase.
