I use regurlarly ableton analog, NI Massive and FAW Circle, whith which I can produice more or less any sound i like, but I can get, at all, how synthesis works and how to make a sound with it.
Do a Google search and you can find many references on Frequency Modulation (FM) synthesis and how to use it, compared to subtractive synthesis, additive synthesis, and other types.
Crude analog frequency modulation synthesis was a feature of some early analog subtractive synthesizers. However, a powerful form of FM synthesis in a digital implementation became extremely popular in the early 1980s with the release of the Yamaha DX7 family of synthesizers. There was a lot published on FM synthesis around that time.
