Atmos Object audio doesn't appear in Multichannel Gain plugin, Logic Pro 10.7.8
In Logic Pro Mac 10.7.8 (most recent iteration) when mixing to atmos, I have the Multichannel Gain plugin applied both before and after the Atmos plugin, and I'm not getting any sound out of either multichannel gain plugin. This happens when I have the multitracks converted to objects; however when I leave them as bed tracks the multichannel gain works as it should. Can anyone help me with this?

      Thanks, Adam.

      I want to make sure the song stays under -18 LUFS. When I have a mix that contains both beds and objects, do I need to monitor 2 separate Loudness Meters, one for the beds (before the Atmos plugin) and one for the objects (after the Atmos plugin)? Sorry if this is a newbie kind of question, but I can't seem to find this out.

    Hi,

    No worries. This isn't that intuitive. As the expense of giving you another link, we did do a write up for this here:     https://professionalsupport.dolby.com/s/article/How-Should-I-Measure-Loudness-in-Logic-Pro-Using-the-Integrated-Dolby-Atmos-Workflow

    In a nutshell Atmos loudness measurement is done from a 5.1 render so all the bed and object audio is included. Making overall gain adjustments can be a bit tricky. We do have the Dolby Atmos Album Assembler that allows for gain, limiting and EQ to applied to Atmos masters. It is designed to be used in conjunction with the Dolby Atmos Renderer but you could get close without monitoring and import the result back into Logic for QC. There are trial versions of both:     https://customer.dolby.com/content-creation-and-delivery

      Is there a workaround to make overall gain adjustments to the atmos mix (beds and objects) without the Dolby Atmos Album Assembler? It looks great, but I can't afford it.

    Hi,

    You can use VCAs to make global gain adjustments in Logic Pro.

      I selected all the tracks in the mixer and selected "Options" > "Create New VCA for Selected Channel Strips." Then when I try to control the loudness using the master VCA fader, the object tracks visually decrease in volume in the Level Meter, but the bed tracks don't. This happens whether I monitor through 5.1 or the Apple Renderer.

      I searched on YouTube and google and can't find anything that addresses this specific issue. I would greatly appreciate it if you could give me a little more guidance. Thank you!

    You'll need one VCA for the bed and then it is up to you how many VCA's you want to use to control the Objects. You could use one or use multiple VCA's for each group of instrumentation if that makes sense for your project.

    Best,
