Dear Friends

I'd like to ask, has anyone managed to track down the schematics of these rom cards?
I found some internal pictures for them, and i'd try to track, but if anyone else has done it ... :)

Thank You in advance!

Nine sine waves from 6 operators? Do tell.

If you can find patch lists for downloadable sound banks, there's one I placed into my bank called Jumpies that sounds right for the stuff EVH used on 1984.
Also note that the DX7 can be configured so there's nine sine waves, so it'll do useful drawbar simulations. (This was covered in a Keyboard Magazine item some time ago)

Thank to everyone for the great information. The other thing is how to hook the DX to a computer, and, Mac is my preference since I own an iMac and an iPad. I also may purchase a MacBook Air or Pro for this and some other jobs. I also have iConnectMIDI which I’m pretty sure will make the connection since it has USB, midi and lightning connectors. Now to start reading the great stuff you guys sent and getting things going. My main program to load or dial in the the OBX sound Van Halen uses on Jump. One of the bands I play with is doing a Van Halen tribute set in 4 weeks and I would like to use the DX instead of my SK1-73.

Important news… I will order KX88 membrane panel, if another 19 owners are interested in the purchase and it will be produced. He offers also DX7 (classic and new), Kawai K3...

Hello from Sweet Discrete,

I hope you are all safe and well.

Just a brief update to let you know the following :

1. DX7 MK I membrane panel batch no.2 is ?on its way, so please place your order, as we cannot guarantee supply. If demand diminishes we may not order another batch going forward.

2. We have secured a Yamaha KX88 and may develop this next, depending on interest. We are looking for a minimum of 20 orders to give confidence it's a go, but would need to be selling 50+ to be a realistic business venture !

3. Manufacturing centre has been moving, in the middle of this pandemic and untold complications have arisen, plus some supply issues, but mostly all behind now so progress is expected...

4. Please, if not already done so, subscribe to our YouTube channel :?

5. Stay safe, be lucky, bye for now

All the best,

Excellent post, Bruce!

Hello Kevin,

Just to add on to what Bruce said, there is a free Oberheim plug-in called
“Obxd” available as an Audio Unit or as a VST. Works great in GarageBand,
MainStage, ProTools and Logic Pro X. There is already a “Jump” preset
available in this AU. Check it out.

For storing patches from your DX7 and for uploading patch(es) to it "SysEx
Librarian” works well (in addition to your DAW of course).

Happy Gigging,

Hi Kevin,

I won't say that you *can't* get an OB-Xa sound on a DX7, but it's
definitely a 'walking against the wind' task! The OB-Xa is an analog
subtractive synth, a la Moog Arp, Prophet, etc. EVH used a pair of
sawtooth or maybe mid-width pulse waves and some detuning. One can
simulate this with an FM synth, but the end result is far from perfect,
IMHO. It's definitely outside the 'sweet spot' for FM synthesis. (Think:
snappy basses, realistic brass, and shimmering bells.)

The Jump! sound is easy to create on just about any analog or virtual
analog poly synth around: Dave Smith, Roland, Korg, Behringer, Arturia,
even a Nord Electro or Stage. But not so much on a DX7.

OTOH, it will still probably be better than an SK1, if that's your only
alternative!

________
The general rules for analog waves on an FM synth are:

Wave Op1 (Carrier) Op2 (Modulator)

Sawtooth 1.00x 1.00x
Square 1.00x 2.00x
Wide Pulse 1.00x 3.00x
Thin Pulse 1.00x 4.00x or 5.00x

Go easy on the amount of the modulation. A little extra modulation from a
third operator at the start of the wave may help to add grit; it should
have a very short envelope. Use an algorithm like #3 or , #4. Start with
the 2nd chain muted, and get a saw wave sound that you are happy with on
the first three operators. Then duplicate that sound on the second three,
and use frequency detune to get the proper mix and swirl.

One other thing: FM synthesis tends to be a bit more 'cold' and sterile
than analog synths. Players sometimes complain about a "lack of bottom
end." I often compensate by adding in some sine wave to fill in the
bottom, but one can't layer sounds on the DX7, limiting your options. You
might try getting the base sound with just two operators, using something
like Algorithm #5 or #6. Use operators 1-2 and 3-4 for the sawtooth/pulse
sound, then turn off operator 6 and mess around with the level of operator
5 (sine) to fatten the bottom end.

Good luck!

Regards,

-BW
