If you see the warning message displayed below, click **Setup MidiJack** to complete the installation.&#x20;

{% hint style="info" %}
This adds the scripting define symbol **MIDIJACK** to the Player Settings, which enables related features in Timeflow. If this symbol is missing then script compile errors will report that the type or namespace 'MidiJack' cannot be found.
{% endhint %}

If for some reason the auto-setup fails, the scripting define symbol may be added in Project Settings / Player, as shown below.

After scripts are done recompiling, the warning will go away and you can now start using MidiJack. With a MIDI device connected, enter play mode to test input.
