Baryon Desktop 1.2.0

Released August 14, 2026. Baryon Desktop 1.2.0 adds two-way OSC and MIDI control, an OSCQuery-powered TouchDesigner surface, OSC Structure Export v4, expanded visual controls, and a more tightly synchronized Performer output path.
Version 1.2.0 changes render defaults and the engine response. Recheck any show-critical presets before performing. Max Quality is now the default profile; switch to Auto when you prefer adaptive quality targeting 60 FPS.

​
Control Baryon from OSC and MIDI

The new Control I/O panel accepts OSC and MIDI control-change input in Performer Mode.
  • Learn knobs, faders, buttons, color controls, and camera targets from one searchable MIDI target list.
  • Map an XY surface to independent horizontal and vertical orbit axes with Orbit XY learning.
  • Control camera distance and trigger Camera Home or Orbit Center.
  • Choose Session only for temporary OSC/MIDI changes or Remember to save changed visual settings.
  • Use Immediate takeover for synchronized or motorized controls. Use Pickup for fixed physical faders when you want to avoid value jumps.
MIDI notes, pitch bend, aftertouch, relative encoders, camera pan/roll, and camera-motion recording are not part of this release. See Parameter automation for setup, addresses, MIDI learning, takeover behavior, and camera ranges.

​
Keep external controls synchronized

Controller Output sends Baryon’s current control values back to compatible OSC and MIDI surfaces. A TouchOSC fader or XY marker can therefore follow a change made inside Baryon instead of displaying stale controller state.
  • MIDI returns the values for learned mappings to the selected output.
  • OSC returns every current-valued public automation target to the configured output host and port.
  • Buttons and other actions have no persistent value to return.
  • Recent MIDI output is ignored if a virtual bus echoes it back as input, including delayed or out-of-order fader values.
Earlier camera-only feedback settings migrate to the broader Controller Output configuration where the saved transport information is still available.

​
TouchDesigner control surface

The updated baryon_osc.tox queries Baryon’s OSCQuery server and creates TouchDesigner parameters for the current public control surface. Changes travel both ways when Controller Output is enabled. The component discovers Performance, Camera, Volume, Appearance, Motion, and Logo controls. It keeps Baryon’s input port, OSCQuery endpoint, controller output receive port, Bonjour discovery, and generated controls together in one component.

​
OSC Structure Export v4

OSC Data Out now supports up to 160 active modes at 15, 30, or 60 Hz. Protocol v4 adds transactional topology and state updates, bounded packet paging, recovery keyframes, explicit stream retirement, response-frequency metadata, and first and second circular spectral moments.
Replace older OSC Structure receivers before enabling Data Out from 1.2.0. Use the current baryon_osc_structure.tox or implement the v4 commit rules described in OSC Structure Export.
The 160-mode setting is a transport and active-field capacity. It does not mean that every frame contains 160 modes or that the spatial field resolves every audible frequency.

​
Visual and engine changes

Version 1.2.0 expands the shared control surface:
  • Shape switches between a spherical clip and the full cubic domain.
  • Boundary switches between reflective Neumann behavior and a fixed-node Dirichlet boundary.
  • Pattern Persistence controls how long recognizable cymatic structure is retained.
  • Spectral Chroma adjusts spectral color vividness without blending in the configured static colors.
  • Max Samples, Laser Bending, Caustic Strength, and Laser Focus expose the current presentation and optical controls.
  • Max Quality is the new default profile. Auto and Custom remain available for adaptive frame-rate control.
The audio-to-field and observer path also changed: modal source coupling, damping, spectral color, water-medium response, and field observation were revised. These changes can alter a saved look even when its stored control values are unchanged. See the Control panel reference for the current labels and behavior.

​
Performer output and reliability

Display, Syphon, and Spout now share one authoritative program-output state. The operator preview follows that stage instead of becoming a second output owner. Recovery, display disconnects, resolution changes, and helper restarts therefore preserve one clear live-output path. Performer output remains opaque over black. Use Add or Screen blending in a receiver when black should disappear. See Program output for platform setup. Version 1.2.0 also improves:
  • MIDI device reconnect and unavailable-device recovery;
  • live-input status and file-playback recovery;
  • file queue and compact player behavior;
  • support diagnostics and renderer-memory reporting;
  • display precision for OSC float values such as 0.4; and
  • WebGPU recovery and native-output diagnostics.

​
Upgrade checklist

1

Update the app and TouchDesigner components

Install Baryon Desktop 1.2.0 and replace older copies of both TouchDesigner .tox components.
2

Recheck render performance

Open a representative preset. Keep Max Quality when the system holds the desired cadence; otherwise select Auto or set a Custom FPS target.
3

Verify Control I/O routing

Confirm OSC In, OSCQuery, Controller Output, MIDI input/output, and OSC Data Out ports. Learned MIDI mappings are separate from OSC addresses.
4

Test the real receiver path

Move controls in both directions, reconnect the controller, and verify a real TouchDesigner, Syphon, or Spout receiver before a show.
Listener Mode runs on macOS, Windows, and Linux. Performer Mode, stage output, OSC/MIDI automation, and the Baryon Pro trial remain available on macOS and Windows; Linux Performer support is not included in 1.2.0.
