Well, you need to have the latest version of H9 Control installed, v1.6. You can check what version you have by clicking on the Settings button in the bottom right corner of the screen and going to About.
If you have the latest version installed, you should find the Looper algorithm grouped under the TimeFactor algorithms (in the Algorithm screen) at the bottom of the list. When you open up any Looper preset, by click on the Info button in the top of the screen, a detailed help file will open up.
