Yamaha DX7 Synthesizer


From WikiPedia – – The Yamaha DX7 is an FM Digital Synthesizer manufactured by the Yamaha Corporation from 1983 to 1986. It was the first commercially successful digital synthesizer. Its distinctive sound can be heard on many recordings, especially Pop music from the 1980s. The DX7 was the moderately priced model of the DX series of FM keyboards that included DX9, the smaller DX100, DX11, and DX21 and the larger DX1 and DX5. Over 160,000 DX7s were made,[citation needed] and it remains one of the best-selling synthesizers of all time.

    There is something curiously interesting about the DX7. After its introduction every manufacturer including Yamaha tried to surpass its design (a very normal thing to try and make it better) in terms of sound and looks. So they added the capability of layering and even effects and even took synths a step further and turned them into sample playback devices producing real sounds such as pianos, guitars, sax, etc. All really great, except that now we are re discovering that the DX7 had such an attractive and amazing sound characteristic which does not need any effects to enhance its sonic beauty. The DX7 is highly sought after now. The magic never left. It's as though time allowed every one to do what they thought were improvements and here is a dedicated site proving that the DX7 ranks among if not the best synthesizer in history. I predict that many musicians that own the Motif Es', Fantoms, and the Tritons and Oasys keyboards will hit those great music spots around the world and start playing their DX7's with NO EFFECTS so that the world can once again hear the sonic beauty of this vintage phenomenon. THE YAMAHA DX7!!

    This is a really great synth of which I have reviewed at least twice before here, and at Harmony Central. I am back to offer some advice and a few words of warning when you inevitably have to have a new backup battery installed. I had this done a couple of months ago and was altogether not satisfied with the result. Luckily, due to research I managed to rectify the problem myself.

    When I got the synth back, one of the keys (second A# from the top) was stiff and felt as though it was sticking or, even worse, the key pin or spring was damaged. I had to open the bonnet and lift out the keyboard unit and beneath, there is a wide ribbon cable that connects the keyboard into the internal CPU. This cable had not been replaced in exactly the right place (there's not a lot of room so it has to be put back in exactly the right place so as not to get caught in the key mechanism). Once I managed to get it in the right place it was good as new but for anyone who has to go out to a technician for a new battery, before you come away, check ALL of the keys (I think I checked them all except this one!) and if you experience anything wrong make them put it right!

    One final endnote, there really is no other synth out there like the DX7. Well done Yamaha, even all this time later!

    What a curious synthesizer! I got my Mark 1 DX-7 last year and I like it a lot. First of all, right now I am doing industrial tracks, and since it can make sounds that sound like hitting metal, well that is very useful. And then there are those digital harsh sounds it can make which is also very useful in industrial music. But, its is also GREAT at other odd sounds that only FM can bring. Like, stormy pad sounds ("St. Helens"), or unique metallic PWM sounds. Or droney pads or nasally, buzzy sounds (Like "Wasp Sting") It's great with basses, and can reproduce a slap bass sound almost flawlessly. The keys are a whole lot like the ones on my Dad's Ensoniq EPS. I love those membrane buttons and how they click. It is very heavy, but not too heavy, and is a headache to program. But I don't do it manually, I use DX manager. I actually did see how bad it was to program, and I programmed the Fulltines sound with a datasheet. It gave me a headache, and I had to take a break. But it sounded like Fulltines, and I was happy. This is a cheap, historic, interesting synth and you need to buy one before Trent Reznor breaks them all.
