I've been watching these videos ripped from VHS done in the 80's (I think) from the New York School of Synthesis. A bit cheesy but very informative for the beginner. I really enjoyed them and learned a lot so I thought I would share.

Intro to Synthesis Part 1 - The Building Blocks of Sound & Synthesis


Intro to Synthesis Part 2 - Types of Synthesis & Programming Examples


Intro to Synthesis Part 3 - Additional Synth Features, Performance Controls
