There are links to example patches here: Organelle Patching Tutorial Videos
This might be because you have closed the mother.pd file.
This video says to use the USB Drive for patching, but that is not necessary for the Organelle M. You can patch right from the SD Card with the M. Everything else in the tutorial can be applied to the M. (Please note that you will see a shortcut to a USB drive on the Desktop even if you do not have a USB drive connected. This is normal.)
