Do i need CabMaker?

Hello,

i have been reading, searching the forum, and asked my Kemper dealer questions about CabMaker.
i have successfully updated my OS to he latest version, and i have got RigManager on my computer.
i made a backup of my Kemper, and eagerly await the 4.0OS !!!
So my reading/research has been fruitful up until this point, but to no avail concerning CabMaker :

i've read various things whether as i need to install CabMaker 2.0, OR NOT?!?

My learning curve is 'slow as Mole Asses', i guess! ;op

Anyone care to kick me in the right direction concerning CabMaker, plz?

tyvm, paults.
For now i just wanna learn my Kemper, and play guitar with the Kemper's loaded presets.
I'll keep learning & gaining knowledge, and then attempt to convert IR files to Kemper Cabinets and such.

thanks for setting me straight on this.
