Yamaha DX11

“The Yamaha DX11 – successor to the more famous DX7 but with some crucial differences. Wheras the DX7, DX100 and all the previous synths in the DX family built everything out of Sine waves, the DX11 offered other waves like saw waves to construct much more gritty & interesting sounds.

But my personal favourite thing about the DX11 is its chip is incredibly close to the soundchip in the Sega Megadrive! So if you want to recreate a lot of the iconic sounds of Sonic 2, Streets of Rage & all the rest – this is the synth to do it,

The synth is all fully functional and in good condition since it’s older than I am, scarcely a mark on it. Its only flaw is the Ram battery has expired – all this means is that if it gets unplugged any user data doesn’t get stored. In practice you just factory reset the synth when you first turn it on (edit+16+32) turn off & on again and everything is working as it should.

I’ve been using it like this for several years, but after a few thin paycheques i’m having to trim down my audio gear & sadly that means this has got to go too. A Ram battery fix is a fairly easy job – i’ve done it before with another synth but never got round to it with this.

By the way this has a two pin power flex but includes a normal 3-pin Uk plug adaptor.”

“Yamaha DX11 FM Synth. Great condition!

All keys are fully functional with no problems at all.

Works perfect. There is a small chip (see picture) but it doesn’t affect any functionality of the synth.

This keyboard was taken care of and kept like a baby for the few years I’ve had it. ”

“Selling a Yamaha DX11 in cosmetically very good condition. All keys, sliders, wheels, and aftertouch work. There is, however, a bugginess where some of the higher patches selected will go into a function or edit mode instead of straight to the patch. The workaround, I have discovered, is to press the “internal” button right after, to actually go to those patches. This occurs when choosing Bank B as well, and is remedied the same way. My guess for the permanent fix is to upgrade the firmware EPROM chip.

That aside, it’s a very clean board and it sounds great. Selling as is and asking for $100 cheaper than the current going rate considering the abnormal behavior.”

” The synthesiser is in excellent working and cosmetic condition. I’m no longer using it enough to justify keeping it and would rather it go to a good home. It’s a great synth and I’ve used it on loads of recordings. I especially like the synth toms and pad sounds. ”

” I bought this as a non working unit. The power supply had some loose solder joints which have all been repaired. Factory settings were dumped into it with sysex MIDI and sound superb! The synth was disassembled and cleaned head to toe! I was planning on keeping it so I did a very thorough cleanup of all the contacts and inspected all boards for corrosion. The buttons were ALL replaced ALL 48 TACT SWITCHES ARE NEW! No hard pressing or anything at all which is VERY nice. New battery installed so that’s good for another 20+ years.” Click here to search for synths on eBay

“Great vintage synth in exceptional condition for its age. Its not mint but for a 30 year old keyboard, it has minimal scratches and cosmetic marks. I don’t think it has seen serious use and it certainly hasn’t been heavily gigged!

Recently serviced with new RAM battery – this keyboard is good for another 30 years! ” Click here to search for synths on eBay
