During the first task I made a video player, that can be controlled by clapping or other loud noises.
You can find the patch right here File:Felix task1.maxpat
If you have any trouble using or understanding the patch, just watch this video I made
https://youtu.be/OLNWtlZIGB4
-edit-
I added a simple interface, so the patcher now automatically opens in presentation mode, to show only the buttons and objects necessary to run the patch. You can disable the presentation mode and see the whole patch by clicking this button on the bottom left corner of the application.
Also the patch now looks slightly different from the patch in the video, and the interface cannot be seen in the video, so don't be surprised.
