Setup - Zoom OSC with XP24

Zoom OSC with XP24:

We have created a Zoom OSC configuration for our XP24 panel. This means that everything is taken care of automatically by Reactor.

By standard it's set up to auto populate, meaning that as users join the call they will be assigned a button. From there you have full individual control. You will have settings like, toggle mute and video, and more advanced settings like if the attendee is in spotlight or pinned. And all of these settings is right at your fingertips!

We have made it easy to change settings for all your attendees by making dynamic user commands. 


Step 1

Control - Zoom OSC from XPoint24

How to run Zoom OSC from XPoint24

Here is a run-through of the standard configuration for Xpoint24

Global Settings

The first thing you will see when you start the meeting is global settings in the top row, and a user row on the bottom.image-1651753663068.png

  • Auto Populate
    This is on by default, and therefore the Host user has been assigned slot User 1. When Auto populate is active, attendees will automatically get assigned a button from the lower row. This can be set to be default or not in the core config.

  • Reset all
    This button resets all the attendee buttons.

  • From first
    This button resets all the attendee buttons, and populates them randomly from the beginning.

  • Empty
    This button puts all the attendees that are not on buttons already, on the next free buttons. This is helpful, if you do not want to use Auto Populate, but needs to get a lot of attendees down on buttons easily.

  • Lower hand All
    This gives the ability to lower all raised hands from one button

  • Meeting - Hold to end
    Hold for X seconds, and the meeting ends for all user

  • User Count
    Here you can see how many attendees is in the meeting

  • Set Speaker/Gallery
    The top of this button changes the view state between speaker and gallery view. When in gallery view, the sides of the button changes the gallery page.
  • Allow Unmute
    Toggle if attendees should be able to unmute themselves 

  • Group
    Grouping attendees can give you the same individual control of users (See Attendee settings
    ), just for a group of attendees. To group attendees, hold this button, and press the attendees you want to group.

  • Select User
    This can be used by placing a 'Selected User' on one of the attendee buttons. Then this user can be changed easily by cycling through them on this button. This makes it easier to manage a lot of attendees without having them all on different buttons.
