Recently I got myself an old but still decently functional Yamaha DX7 IID. Out of the whole Yamaha DX lineup of synthesizers that changed and defined the sound of the '80s, DX7 was by far the most popular and accepted. Vintagesynth.com calls it "one of the most popular digital synths ever". It introduced FM synthesis to the widest possible audience, yet it got the reputation of being extremely hard to program (mostly because of it's unfriendly interface), so pretty much everyone stuck with presets that plagued great majority of records released at the time.
My introduction to powerful and extremely flexible FM synthesis was through Ableton Live's Operator which got me instantly hooked. To be honest, apart from FM (and my Korg X3R's own unique algorithm), I haven't got that much clue about more usual synthesis methods. Which is a bit strange considering how many people are in exactly the opposite situation. That's why DX7 seemed like the most natural choice for me, and is supposed to replace X3R in time. And I admit - it's also a bit of a fetish thing :)
The model I purchased is the second generation DX7 (tagged DX7 IID) with few considerable advantages, such as keyboard split and dual modes and pan control (the original was entirely mono).
All in all this is just one short post obviously meant for bragging. But I intend to seriously devote my time to this classic machine and for that purpose I opened up a separate page (see the link near the bottom of the right side menu) to stock up all the useful resources for like minded DX7 enthusiasts.
