# Assimilate Scratch

{% hint style="info" %}
OmniScope automatically discovers the Assimilate Scratch plugin when Scratch is running. The **Assimilate Scratch** source will appear in the Connect dialog without manual configuration.
{% endhint %}

The SDI plugin for Assimilate Scratch is installed automatically on Windows. On macOS, select **Options / Install plugins…**

Now the SDI plugin needs to be configured in Scratch. On the main page select System Settings…

Then “Configure..” in the SDI Settings section:

And finally select Nobe OmniScope plugin in the list and set the options as follows:

**Make sure** the Channel 1 is enabled! Otherwise the signal will remain black in OmniScope.

Once the setup is done you can now connect from OmniScope using Assimilate Scratch source.
