Using ZoomOSC in your Zoom meeting

Events have undergone a massive change in the last few months. Online events have taken a new meaning. It means we can expect to see a new level of creativity and skill to transform the simplest of video meetings into an engaging new experience. It opens up the possibility of removing geographical limits. d the geographical limits.

During this time, we all have used various meeting platforms like Zoom, Microsoft Teams, Google Meet etc. Among these, Zoom has become a name of household name simply because it is being used in primary school classes, board meetings, major events and much more.

We have used Zoom and the other tools in more than a hundred big and small events. It has a rich feature set but from a creativity viewpoint, we were always looking for ways to extend functionality or simplify workflow. This means we noticed good features and limitations in certain scenarios.

Can we do more with Zoom, has been our constant focus.

In my research for plugins, study of the APIs I came across the OSC protocol and that discovery led me to ZoomOSC. This service extends the core Zoom meeting functionality and makes it easier to delivery good meeting experiences.

You basically use the ZoomOSC client to extend the Zoom capability. It makes use of Zoom’s API and uses the OSC protocol to give you more power. The power to connect many things. Over the course of the next few posts, I will detail them all. (

First things first, ZoomOSC by default runs on IP or localhost and port 9090. You always have to ensure that you use these values in you OSC software or hardware to interact with ZoomOSC.

Initial Challenge – How do I test? 

The initial question that I was faced while testing ZoomOSC is to have a meeting setup with multiple participants. If you are a group of people with similar interests and want to check the ZoomOSC it will be easier to test it, but even if you’re alone or a small team, there are several ways by which you can setup and join meeting with multiple participants. I have listed few below:

A) One of the easiest ways is to use multiple devices to join the meeting like most of us have at least 2 to 3 devices that can be connected to the zoom meeting. Use your main/primary machine to host a meeting. Join that meeting from your mobile phone, tablet, iPad or secondary machine. By this method you can join the meeting with as many as participants as many devices you have. 

B) Another way is to make use of small shall script that will open multiple instances of ZoomOSC application. You can create that script yourself or there are some available if search on Google. You can also send a request in contact form if you want and I can provide one for you.  

C) If you are not confirmable with writing or running a shall script there is also an easy method to open multiple instances of ZoomOSC client on the same mac. This will work same as the default ZoomOSC app works. The steps to open multiple ZoomOSC instances are:

Open your Applications window in finder.

Right click on ZoomOSC app and click on “Show Package Contents”.

Goto Contents-> MacOS and click on ZoomOSC to open new instance of ZoomOSC.

This way you can open as many instances as you want and keep joining same meeting with different names. This works similar to the shall script, you are just doing all steps manually. 

The next step is to make use of ZoomOSC in a live meeting scenario. I will post soon.
