If I could advise some specially worthy readings, that would be the "Synth Secrets" series of articles from Gordon Reid, which started publication in Sound-On-Sound in May 1999.
This is a major effort of vulgarization towards synthesis fundamentals (and much beyond), with minimum mathematics.
The Mg Modular V, being a full modular synthesizer, is a perfect tool to practice such theory. The "Synth Secrets" in one hand, the MMV in the other hand, and the MMV user's manual in a third hand, in a short time you will get pretty nice analog synthesis skills, which is *the* key to synth programming (inspiration being another subject).
And as we live in the best of all possible worlds, these articles are freely readable
online (Secret #1 starts at the bottom of the page).
Hope this helps
