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.

Here's my DX7 mk1 ..........http://youtu.be/_hHdqNTD8lU
It broke today after I had spent weeks programming eps and amazing electric basses and Oberheim funky analog stabbing bass sounds. I love this keyboard and hopefully will close a deal on a DX7s for $200

I have a Mk2 DX7S, a fabulous keyboard for the jangly electric pianos. The keyboard has a semi-weighted, heavier spring feel than the average synth, I like it.. Does anyone know if the mk1 Dx7 has the same springing as the Mk2.??

You totally missed my point, which was I don’t understand how the TG77 can possibly be noisier than any older synth, since it had better DACs and other circuitry than all synths that came before it. The unit David heard must have had some problem.

As for your reply, which was unrelated, I’ve no interest in an fruitless debate over sound quality and how useless words like “special” are for describing it.

Incidentally, though, I get a bit confused by how people pay so much money for a mark I DX7 with its puny single timbre, specifically because they want poor sound quality ;)

Daniel: It's not just about the outputs. You can't say that just due to higher bit and so on that it sounds better. Often better spec converters can sound more sterile and loose the special sound character that was in the older concvertes
