Some people sugest to use Rocksmith DLC Builder for creating CDLC's instead of the RocksmithToolkit. So i'll give it a shot. But is there any manual or tutorial available on how to use this program?

There are, here is one by Arrov. He just recently added a how to using DLC Builder to his guide:

I will also suggest to use DLC builder, as certain things are much much simpler, and easier to get done, with less errors than Rocksmith ToolKit. I am not bagging on the Toolkit, but I got nothing but errors when I started my first chart couple years ago. I just gave up after them not working.

Recently I attempted again with [toolkit] and again errors.

I am not saying it is idiot proof, The first laptop I tried it on, adding a preview didn't work as well as something else although the chart worked. I went to add lyrics to my first chart that turned out ok (using DLC Builder) and it completely messed up the DD.

Life called me away to concentrate on other things at them moment for me to say why and what I did wrong, and get back to trying to make a couple charts. My point was though all though not idiot proof, It is really much simpler to use (for me).

Hmmm nice HMI, but wwise 2019-2022 is like impossible to get. This forum hosts 2013, and you can find he new 2023+ version. But nothing is compatible.

It's almost like there's a page on CF in order to download WW2021
