Yamaha DX9

Yamaha DX9 Image

The DX9 was a not-so-special spin off of the aggressively popular DX7. The DX9 wasn't a great synth, it had all of the headache problems associated with its DX7 relative. Difficult programming and limited MIDI implementation to name a few. Still, it is a 4-operator FM synth like the other DX synths and is capable of interesting sounds.

In the mid eighties when the DX9 appeared it was a welcome cheap alternative to the DX7. But current DX7 prices have nearly hurled the DX9 into obsolescence. Also, unlike the DX100 which is famous now for its gritty house-bass sound, the DX9 doesn't have any particular sounds that set it apart from other synths like it.

Yes, a DX9 is a 4-op FM synth. And yes, so is a DX100. But there are much more differences than just the keysize! The DX100 is (more-or-less) SysEx compatible with DX21, TX81Z, V50, and some other 4-op FM synths made by Yamaha. The DX-9 is NOT SysEx compatible with these models. And also the FB-01 is a 4-OP FM synth, that is NOT SysEx compatible with the DX100 nor with the DX-9. Let's not spread inaccurate information on the internet.

some interesting sounds to be found in here. but if you cant afford a dx7 ,this should do the trick until you understand it capabilities and itch for more. i do happen to enjoy this more than the sy77 i used to own but dont get me wrong the sy77 is far superior to dx9 but i seem to like membrane programming and simpler 4-op limitation. i say let fm synthesis live forever and yes i have much dx9 love.

When all has been said,and it has,it is a good midi controler,use mine to run my jv1080.though it can produce some massive subsonic noise and I have used the celest sound modified in recordings,There are many better synths to have,though for the price if you have a limited budget ,or are just curiouse....why not. have had mine for years with no problems.

To clarify a few erros in previous posts and the review the DX9 is a 4op FM synth (same synth architecture as the DX100, DX27). The differences are the key size and amount. Their synth engine, buttons, and layout are identical.

Any sound you can make with a DX100 you can make on the DX9 using the same parameters, etc. The DX7 has a different architecture (it's a 6 op synth for one) and it IS capable of sounds the DX9 is not. There are also differences sound structure and keyboard (velocity, etc). Finally there are different DX7 versions but all are 6op. Unlike the DX9/27/100/etc.
