Beam for Max v0.1.14 (RC1)

Beam for Max 0.1.14 (RC1)


We are happy to share a new Beam for Max version, which is also the first release candidate for Beam for Max 1.0.0!

Fixture profiles v3

Introducing a new fixture profile format with improved support for various fixture properties.
This allows us to better support a larger range of fixtures and grow the fixture library faster.

Fixture color spaces

Improved color and intensity translation from Beam’s color modulation keywords red/green/blue to different fixture color spaces. In a fixture profile, the relevant channels are specified as additive (intensity/red/green/blue/white) and subtractive (cyan/magenta/yellow) components, for which an appropriate color space can then be chosen, replacing the fixture profiles v2’s transforms.

The currently supported color spaces are:

  • dimmer (intensity)
  • RGB (red/green/blue)
  • RGBI (red/green/blue/intensity)
  • RGBW (red/green/blue/white)
  • RGBWI (red/green/blue/white/intensity)
  • CMYI (cyan/magenta/yellow/intensity)


A single fixture profile can now contain multiple DMX modes within a single profile.
This eliminates the need for a separate fixture profile for each mode.


Added support for fixtures with cells and subcells of any level, such as pixel bars and fixtures with multiple fixture “subgroups”, with all the cell information stored within a single fixture profile.
Eliminates the need for multiple fixture profiles for every fixture cell/child type to describe a single fixture profile, as is needed with v1 and v2 profiles with aggregates/children.
Patch Editor now supports editing tags of individual cells and children.

Test any attribute

A fixture’s testOn value in a patch (activated using the Test button in Beam for Max’s Patch Editor) previously only had impact on intensity and color channels, but it is now possible to test any attribute of a fixture, such as pan/tilt of a moving head, or strobe rate of a strobe.
When Test is active, Beam for Max sets a fixture’s channel to the highlight DMX value specified in its fixture profile.

Fixture metadata

Profiles now contain info about fixture manufacturer, model and profile version. This is part of the profile metadata dict that beam.core returns on get_profiles_metadata.

Updated fixture library

  • Added 141 new fixture profiles.
  • Existing profiles were converted to use format v3.

Support for legacy profiles

Profiles with schema v2 (the version Beam for Max worked with until now) continue to work, and profiles schema v1 (Beam for Live 1.x) are now supported, but are both deprecated, and some features are not supported.


  • Added fixture profile v3 JSON schema documentation file (Beam for Max/docs/tutorial-patchers/sbf_v3.schema.json), as a reference for users who want to create own fixture profiles.
  • Beam for Max - Setting up tutorial patcher:
    • The v3 schema included in the section about fixture profiles.
    • Embedded “Generic RGB” example profile updated to v3.
    • Added links to forum and fixture profile requests site.
    • Fixed paths in comments referencing files within the package.


  • beam.sig: fix for a crash when inputting dicts from another thread (with Scheduler in Overdrive).
  • Demo Set visualizer: fix for the visualizer sometimes not opening (node.script: Unhandled Message: "openvis" error).
  • 16-bit attributes DMX value precision: fix for an issue where modulation values were incorrectly translated to DMX values of attributes with coarse and fine channels.
  • Package info: adjusted description and updated logo.
  • Updated Beam for Max EULA.
  • When Beam for Max is not authorized, DMX values of all output universes is periodically set to 0, instead of pausing output, as the latter proved to be confusing for new users.
  • beam.dmxio: show pop-up when output is paused, as beam.output does.

You can download the package here.


Before I update, are there any specific instructions for updating an existing installation to the new v3 schema?


Hi David, thanks for the feedback that helped with fixing the beam.sig issue!

  • As mentioned, fixture profiles v2 still continue to work.
  • Any patches that are referencing fixtures that were previously v2, but are now replaced by profiles v3 should continue to work.
  • To make fixture profiles v3, you can use the JSON schema as a reference, in combination with some of the factory profiles in the misc/profiles folder. Besides just opening the schema as is in a code editor, you can also try one of the online JSON schema viewers.
  • If you need help converting older profiles to v3, please reach out.
  • As always, please thoroughly test everything.

Please let us know if you have any specific questions.
