I want all those synths he's got. Man, so retro! Painfully so! I'd give up my daw and interface just to have a decent couple of analog Rolands or Oberheims and a 8 track cassette mixing board. At least for a while. Might be fun.
Also I came across this the other day, I think it is a very good intro to understanding not only how different parameters of a synth work, but how to train your ear to identify certain sounds. Its basically a piece of software which teaches you, and then quizes you and gets you to identify and make the sound with its in built synth.
However it is fairly expensive, check it out its called "Syntorial"
