@whale-av I understand the the mechanics of pd. However, the tutorial did not mention how I can create saw, square and triangle waves. I need help with that.

Hi, I am wondering if it is possible to create an additive synthesiser for a verbos harmonic oscillator: https://static1.squarespace.com/static/52cddaa9e4b0999c86f84b8a/t/56145344e4b0e58796be4889/1444172612979/harmonic+oscillator+postcard.pdf

There are two parts to it, namely the oscillator core and the harmonic mixer. For the oscillator core, it has to output saw, square and triangle waves. How do I do that in pd?
