As im a bit new in that world i dont understand yet how the attenuator, mults and so forth will help me: its a way to increase the potentiality of each module by adding more connexion available ?

Not exactly, they allow you to control your signals in different ways. Maths has attenuators but using those as simple attenuators will quickly become old, and you'll be looking for more. Luckily, attenuating cables exist, I bought some at Schneiders. Attenuators will attenuate (reduce) a signal, useful when sending an LFO to say a filter cutoff, you don't usually want your cutoff being moved for the entire range, the attenuator allows you to control that range.
Mults allow you to copy a signal (say an envelope triggered with your voice, to send it to both VCA and filter), etc. I won't go over what all utilities do, but someone already did, more or less : https://learningmodular.com/ Chris was also involved in the writing of an amazing book as well: https://learningmodular.com/patch-tweak/ Both video courses and the book are fantastic learning resources, a lot of effort went into those. There's also a lot of good free stuff on Youtube as well, for example my favorite Youtuber is Ben DivKid (), his videos are very informative even you don't have the module being demoed, as most techniques will apply to a lot of systems/modules.
