There's more to the re-issue fervor than merely nostalgia or the cheap thrill of owning an old classic synthesizer. There's also the desire to work with a simpler instrument free of menus and that allows a 100% direct experience of designing sounds and making music. It's the pleasure of dwelling for a whole session on the fundamentals of analog synthesis - which are rather basic; but that's where all the magic is. Some of us just don't need or want a plethora of features and even find them distracting; they also make a control panel annoyingly crowded. Personally, I don't care whether a synthesizer is a re-issued vintage or a brand-new design. But there certainly aren't many modern keyboard synthesizers that fit the above description, so the natural tendency is to look to the re-issues. For example, I would love to find the modern equivalent of something like a Roland SH-02, but with a four or five-octave keyboard. What a pleasure it would be to work with such a clean basic spacious panel. But there's no keyboard synthesizer available that comes even close. So, people like me end up looking to the re-issues. That's not nostalgia, it's a love of simplicity and directness in synthesis.
