Upvoted, I consider these valuable for somebody that's going to systematically learn synthesis but for someone just looking to make sense of oscillators/ROmplers/wavetables, filters, envelope and what not, i would just do tutorials on whatever you own: microbrute, bass station2, mopho, ES* models in Logic etc (also probably wounldn't spend much time on theory of Yamaha FM, Kawai additive, Casio phase distortion, which had more marketshare at the time of the SoS series)

Or read the books by Brian Shepherd (Refining Sound) or Rick Snoman (Dance music manual). For somebody serious, there's books by Miller Puckette and Charles Dodge
