Yamaha DX7S / DX7IID / DX7IIFD

Yamaha DX7IIFD Image

The DX7, a classic FM synth, gets a make-over with three significant updates. The updated models feature a more sturdy chassis with actual push-buttons replacing the cheaper and less reliable membrane buttons of the original DX7. The two real time sliders (that allow for control of user-programmable parameters in real time) are larger than before. Internally, the biggest improvement is the updated 16-bit digital circuitry for cleaner and much less noisy sound quality. Patch memory has also been doubled from 32 to 64 voices. Additional general improvements include enhanced MIDI support, micro-tuning capabilities, aftertouch controlled pitch bending, and multiple LFOs.

The DX7IID and DX7IIFD (pictured) models also added bi-timbrality with keyboard split and layering capabilities. This allows two voices to be layered in dual mode, providing very rich combinations of sounds that would otherwise be impossible with the original DX7. Voices could also be split across the keyboard, for a two part multi-timbral performance capability; again, impossible with the original DX7 (or the DX7S, as the S stands for single timbre).

The DX7IIFD added a Floppy Drive (that's what the FD stands for) offering one megabyte of memory space (equal to 40 RAM cartridges) for thousands of voices, fractional scaling, SysEx data and more.

DX7 Centennial

Pictured above in silver and gold is the DX7 Centennial, released in 1987 to celebrate Yamaha's 100th anniversary. Not just a new paint job, this limited edition model has 64-voice internal RAM memory and 64-performance memory, 32-note polyphonic stereo output (2 x 16 voices), and a 76-key velocity and after-touch sensitive keyboard that glows in the dark. Only about 300 were made and it originally retailed for $3,500!

Like the DX7, these updated models may have been used by The Crystal Method, Kraftwerk, Underworld, Orbital, Talking Heads, Brian Eno, Depeche Mode, D:Ream, Front 242, U2, A-Ha, Enya, The Cure, Stabbing Westward.

I bought this synth and was very dissapointed with it having being used to the VST models. Yes the sound is far crisper on the hardware and more satisfying to play but it's just such a cheap catalogue of sound possibilities which is difficult to get away from.
I will side on the fact that if you want to sit on a sound and tweak it for 10 minutes to get what you want then this is for you...I just could not be bothered - not that I didn't understand it, I just don't have the patience to tweak something that would end up sounding dull or typical anyway.

Madonna also used DX7II on her Whos That Girl Tour. You can se it clearly in the intro on the music DVD.

If you own this synth a copy of "the complete DX7 II" (Howard Massey) is highly recommended, if hard to find now, it taught me a lot more about FM synthesis than anything else I ever read or heard.

Still prefer the output of the MK2 to the MK1, cleaner yes but doesn't mean 'worse' as that can sometimes mean.

This synth is from another planet, doesn't sound like anything else out there, in a good way. If you're looking for instant gratification, look elsewhere because this is not the kind of machine where sloppy and accidental tweaking brings the gold.. The difficulty of programming is heavily overstated, FM in itself is easy to learn but takes a lifetime to master, but the interface is as logical as it can be given the controls available, it was much easier to grasp than I had expected, this at least goes for the II. The keyboard has a wonderful feel to it and the synth itself is a tank. A misunderstood and unfairly judged synth by those who are ignorant and cannot stand exploring new things. A true legend in synth history.
