DX7 Stuck in Voice Mode.

Unread postby EAGARDENER » Fri May 29, 2009 9:13 pm

About 6 years ago, my DX7 locked in Octo Mode. I had a service rep work on it for three hours. Paid 300.00 for the service. Result - stuck in octo mode.

I upgraded to another keyboard, but I thought I might drag the DX7 out to see if there might be some way to get it up and running.

Does anyone know how to either get me out of octo mode, or reset to factory settings?

Thanks.

By the way, first post here...so, bear with me.

Hi EAGARDENER,
Welcome to the Forums! I would assume you are talking about a DX7 with E! as that is the only octal mode I'm aware of on DX7s. Let me check my files and see if I can come up with something.

The only procedure I found in my notes (actually an article called "Ghost in the Machine" by Mark Davis from Electronic Musician published May 1989) was for the DX7 mkI with E!.

"The following set of procedures will completely reinitialize a DX7 with an E! board. If you don't want to clear the voice banks, skip sections A and B.

A. Choose a RAM bank.
1. Press Internal Memory Select:
2. Move the data entry slider to choose a bank number.
3. Choose a voice to activate that bank.

B. Erase that bank. Press:
1. The Function button
2. The operator Select button twice.
3. Button 19 three times (answer Yes to bank erase).

Remember to do the above steps to all voice banks.

C. To initialize without erasing voices, do the above procedure, but answer Yes only to Patch Map erase and Keyboard Preset erase. (Button 19 toggles between three parameters while in Function/Operator mode, Bank, Patch Map, and Keyboard Erase Preset).

D. Enter the Function Page to clear and set the Global Function Data. Note that some buttons have more than one function, so to set each parameter for these buttons, simply press the buttons repeatedly until the screen displays the proper function. Press:

1. The Function button.
2. Button 2 (set to Poly).
3. Button 3 (set pitch bend range to 12).
4. Button 4 (set pitch bend step to 0).
5. Button 5 (set Portamento mode to retain).
6. Button 6 (set port/gliss to off).
7. Button 7 (set Portamento time to 0).
8. Button 8 (Midi volume=7, DX volume=7).
9. Button 9 (aux patch=000, main patch=000).
10. Button 10 (Midi curve=Lin1, DX curve=Lin1).
11. Button 11 (Midi high=127,Midi low=16, DX high=127, DXlow=000).
12. Button 12 (Midi shift=000, DX shift=000).
13. Button 13 (keymode=normal, random detune=0).
14. Button 14 (Midi transpose=00, timbre=63).
15. Button 15 (Midi high=127, Midi low=000, DX high=127, DX low=000).
16. Button 16 (Midi out channel=01).

E. Now clear the other Miscellaneous registers. Press:
1. The operator select buttons.
2. Button 7 (cont=off, seq=off, key=off).
3. The operator select button three times.
4. Button 13 (set the led brightness to a comfortable level). Your E! equipped DX7 should now be properly initialized."

Hope this helps.
Clyde

Hey Clyde, this is useful stuff :D

Could I possibly copy this to use in my website? A DX7E! reset procedure would make a good entry (I'll dig out my old '7E! and see if it works).

Cheers.
Steve.

Hi Steve,
That is reprinted directly out of Electronic Musician, I would guess that if you give them credit and list the publication date it would not really be an issue. It really is a great article, that month was Part 1 and had things for:
DX7, DX7II, DX7 E!, DX21/27, DX11, TX216/816, TX81z, TX802, TX7, FB01, RX15, RX11, RX21, RX5, RX7, QX3, QX7, QX5, QX21, Kawai K1, K3, K3m, K5, K5m, M8000, MK10/20, Q80, R50, R100, Korg M1, DSS1, and more, I think they did Part 2 of the article the following month or a couple of months later, I can probably go back through my back issues and find it. The other day I also ran across a copy of Yamaha Aftertouch magazine with the V80 FD on the cover, article has a couple of pictures and preliminary specs. That was the synth that was coming out after the DX7II series, was announced at NAMM and they had a prototype there, several months later it was quietly dropped from production plans and shortly after they announced the SY77.

Turns out I've got a DX7IIFD with E! (been a long time).

Also resurrected all the old instruction manuals and some other related DX7IIFD Books namely:

1. E! for the Yamaha DX7II Series
2. DX7II FD/D Digital Programmable Algorithm Synthesizer Owners Manual
3. The Complete DX7II. by Howard Massey (comes with flexible record disks of: Audio cues 5-28, Audio cues 29-53, Audio cues 54-61, Audio cues 62-71, Audio cues 72-83, Audio cues, 84-90).
4. E! Update For the Yamaha DX711 by Steve Preskitt and Dan Walker.
5. Yamaha DX7IIFD - A New Beginning - Volume 1 - by Lorenz Rychner.

Its like traveling back in a time machine. Long time between this old boy and my KORG...

I checked, I don't have reset procedures for the DX7IIFD with E!, perhaps you can find it on the internet somewhere (and I had a IIFD w/E! many years ago).

Yes, I tried the reset, but it didn't work.
As it turns out, I'm stuck in voice mode and can't seem to get out of Bank 1. Also, I can't change sounds or get sounds or hear sounds.

Readout:
Voice (TR01)E!
BANK 1 E1-01 FFFFFFFFFF

I want to access:
Bank 1 A1-01 (name of sound)

When I turn it off then back on, it should read the above, but it goes back to the first readout.

Stuck here... LOL!!!

BTW this is a ver. 1.20 (1987 I believe).

I'm kind of surprised that the manuals/booklets about the DX7II w/E! didn't have a reset procedure. When I sold my IIFD w/E! back around '91 I sent all of the E! info to the buyer.

Steve, I noticed tonight that they finally took down your site, do let us know when you get it to it's new location as your site is a valuable resource!
