[chuck-users] FLOSS manual new paragraphs

Hi, as I mentioned few weeks ago I started updating the ChucK FLOSS manual (ChucK_FLOSS https://omnibook.pro/chuck). today I also added a new paragraph (Synthesis Basics - Part I https://omnibook.pro/chuck/_full/#synthesis-basics-part-i). the idea is to expand the tutorial chapter offering a gentle introduction to ChucK, that covers several aspects. it would be great if you guys could have a look at it, and give me some feedback. I apologize in advance for my bad English. of course this is a FLOSS manual, so please feel free to contribute :) cheers, Mario
