There is an English User and Installation manual for the Farbwerk360. Google is your friend. I just typed "Aquacomputer Farbwerk360 Manual" into Google and the very top link took me right to the download of the English PDF file. I tried to attach the PDF file but got an error saying the file is too large. It's 1.189MB and the upload file size limit is 1.05MB.
Here is the link to the download.
Farbwerk360 English Manual
You can absolutely control individual LEDs. Aquasuite has a very nice selection of RGB patterns, most of which can be completely customized. I switched from Corsair iCue and am never going back, especially considering that Corsair has decided to drop support for a bunch of their own products, including the 2 H110-i AIO coolers I own.
