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.

"The famous LatelyBass can be created on every 4op Yamaha FM synth to a t, of course that includes the DX9 as well."

I seriously doubt it! A key part of that sound are the non-sine waveforms that were only introduced in the TX81Z, 3 years after the rather pitiful DX9 was released. DX100/21/27/FB-01 don't have those either. Nor the 6-op DX7/II

And as already said, DX9 has lower max modulation index than the other, 'proper' 4-ops

EG rates have different ranges, key and rate scaling are different and so on

So please, do tell us how you can recreate the overrated LatelyBass exactly...

I really wonder who writes these reviews:

"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."

The famous LatelyBass can be created on every 4op Yamaha FM synth to a t, of course that includes the DX9 as well. Yeah, most presets are crap, who cares, get yourself a decent editor and make some of your own. Good things come to those who get up their lazy behinds and create new sounds instead of waiting for others to do it for them.

Also, DX9 does not have the higher maximal modulation index (I) of other 4-op synths by Yamaha. It has the same max ~13.123 as DX7, whereas later 4-op synths go all the way to just over 25. Except FB-01 at ~12.566, but that is another beast.

Why the same I as DX7? Oh, something else that should be made totally clear: DX9 is literally just a DX7 with 2 operators disabled. It offers nothing to compensate like other 4-op synths did (higher I & later, 7 other waveforms). If you want proof it is literally a crippled DX7, check the service manual of either: it is named the DX7/9 Service Manual.

"Still, it is a 4-operator FM synth like the other DX synths"

This is misleading. Not all DX synths had only 4 operators. It's worse in the context of a paragraph where you just mentioned the DX7. That has 6 operators, as do its more advanced relatives the DX5 and DX1. Poor wording like this risks misleading people that the DX7 family is only 4-op and hence that they can get a DX9 and have 'almost' a DX7, which is completely false.

Hi all
If You have an IPhone try the dxi fm app. It's a 4 operator fm synthesizer with filter and effect processing. Use it with my setup. I wonder how close it comes to the DX9. I have a DX7s now and Will try to compare Them.
By the Way for IPad it has several waveforms like DX11/ TX81z etc

I once had a DX-21 and I loved that synthesizer. I Think the DX-9 is underrated.

Cheers
