@farkas is right. My first manual about a modular subject was for the Make Noise O-Coast. The pedagogy of this manual invited me to continue towards modular.
One Make Noise exception: the Maths manual. Fortunately Demonam has been there :) https://w2.mat.ucsb.edu/mat276n/resources/systems/CREATE_teachingSynth/manuals/8c_Maths2013-V1.11-printable.pdf
Otherwise, for their nice readability: Mutable Instruments.
