Hey everybody -

I'm having a desperate problem with my DX-7 II, so maybe you guys can
help.

Everything was working fine, untill one day, I power on, and all of
the Internal sounds come up on the LCD as digital garble (like symbols
and heiroglyphics. They also dont produce any sound.

The cartridgde, on the other hand, works fine.

How can I fix this problem? Will I need to do a hard reset somehow?

It is almost certainly the internal backup battery
which has curled its toes up and died... In the DX7
MkI, the battery is soldered directly onto the main
circuit board, so assuming that the MKII is the same,
you will need to wield the soldering iron. A friend
has done just this on my DX this week. He has fitted a
battery holder, so in another 20 years, it will be an
easy job to install battery No 3!

So, the good news is that fixing the battery is no
great problem. The bad news is that your internal
sounds have gone for good unless you have a backup
somewhere... You will need to restore sounds into the
internal bank either via MIDI and a SysEx copy, or
just copy one of the cartridge banks there to remove
the garbled data which you have now.

Good luck!

Adrian

A friend did mine, but it's a CR2025 I think It would
be better to open the synth first and check - it is a
disc-shaped thing about the size of a 10 pence coin.

The yamaha part number is "PC-900040" and they say it
is a "special type", but it is actually a very common
one (if you are in the US, Radio SHack have them. In
the UK, MAplin or even Boots). The only difference
between the Yamaha part and the standard battery is
that the yamaha one has solder-tags on so it can be
soldered directly into the board. If you buy the
standard one, you will need a holder for it too.

Good luck!

Adrian

Hi, can anyone gimme a link where i can download a dx27/dx100 editor?

I would be very gratefull

Hi,

Here are some DX21 .mp3 demos and information.
DX21 is an 4-operator FM synth with an analog chorus.

http://homepage.mac.com/synth_seal/html/

Hi Group,

     I am a new member and I would like to know how to program my DX7
to get the "synth horn" sound as I hear on Don Henley's 1985
hit "Sunset Grill."

     What should the proper settings on my DX7 be in order to achieve
this crafty sound??? Should I also use a sustain pedal with my DX7?

     The 'horn' sound was actually done on a Synclavier II guitar
synthesizer, according to widoworx, who gave me the answer at
the "Synthesizer" group. Link:
http://groups.yahoo.com/group/synthesizer.

     If anyone here at the YamahaDX group has any proper answers as to
this, please let me know anytime on or off the list.

Thank you,
Benjamin Edge (My2Fights)

I will be out of the office starting  2005-07-05 and will not return until
2005-07-11.

Jag kommer att svara på meddelandet när jag kommer tillbaka.

Hello:

I just bought a DX7.

Just a few questions that I need answered that I could not find doing
a search.

1.  When I do that internal test (function, 16 + 32), my LCD flashes
on and off.  I have to turn the DX7 on and off for it to get back to
normal.  ???


2.  For the life of me, I can't seem to get my DX7 to receive patches.
  I've hooked it (MIDI in and out) to my korg and things seem to be in
order.  I can import sysex data using DX MAnager, but no sounds come
up on the screen.  Currently, voice #1 is a bunch of scrambled
characters and the rest are blank.  ???

3.  Currently, I have not found a way to import or export sounds.  I
must have imported something because I used to have a internal memory
sounds but now I don't.


thanks for your help.


Lane

This sounds like a low battery problem. It's just been
discussed on the list - try looking at the past
messages (within the last couple of weeks, I think)
using the group.yahoo.com interface. There were
descriptions on where to get the parts and how to fix
it.

You definatly need a new battery,there are lots of
posts on the site as to how this is done.If your not
good at soldering take it in to have it done.Your
board will only be good for parts if you mess up.

I don't know of one, but I plan on writing a DX27 editor as soon as I
can afford to buy one (hint to all the people who have downloaded the
TX81Z Programmer but haven't registered :-)  I don't know if I'll do
the DX100 or not.  I think the DX27 editor would cover it, but I'm
not sure.

Matt Gregory

I need lots of DX-7 and other files saved to HD and discs now I have
Dx-7 back and TX-81Z but I hate Acrobat: it refuses to show a save
function ever and snaps to pages instead of scrolling smoothly.
I wish people linked alternate methods and obvious ways to save for
printing and archiving.
Is basic free Acrobat designed to bar saving now under Win98SE or am I
obsolete/not upgraded/too poor??

How can I save these files without forwarding everything to someone
else or printing every single page upon receipt? This has driven me
crazy for a year and I think in years past it was not an issue.

Please do not tell me to get with times and WinXP everything.

Go to link below and get details on battery/voltage test in diagnostic
and how to load default ROM patches again, maybe by hand.

A. Which model DX-7? Mark I or other? Memory carts are different.
B. I didn't think you could transfer non-Yamaha, non-DX files into a
DX-7 at all. If you pump Korg stuff in, it may wreck what you have.
Always back up data before fiddling around, even if onto paper only.
Patch CHANGE info does not always transfer well , especially since
Yamaha did what they pleased with MIDI in the Eighties- DX-7 ain't
General MIDI spec. Dumping Korg patches to DX-7.........forget it.

C. Buy all the good RAM carts you can find, the ones for your specific
model run. Save some for me!
Import/save patches via DX Librarian or DX Manager or such on computer
with MIDI in/out cable and adapter. Don't use a non-MIDI cannon plug.
D. When into the diagnostics, +1 entry button goes forward through
tests, Test 1 should come up, -1 backs up.
Try to get March 1984 Keyboard mag scanned at the article that runs
you through this at back of magazine. I have it but no scanner. Some
tests destroy all data, some never were implemented[ there are about
11.
E.Gather lots of info before you do things; I think a round C2032
battery installed by tecjhnician is neede: you WILL lose all internal
patches during.
http://www.thedx7.co.uk/

Thanks for ALL your help.

I've installed the battery.  DX Manager says I'm dumping info into the
DX7 but my voices do not change.  I've dumped a cartridge into memory,
turned the synth off and on and they are still there....so that is
good...the voltage reads 2.9V instead of 2.8V like it did before.

What I meant with my Korg is that I can control the Korg with the DX7
and visa versa.

But when I first put my new battery in, all I heard were beeps and
boops  (LCD scrambled) comming from the "blank canvas" when I pressed
keys down.


All I want to do is get my synth back to the way it was in 1983.
Stock.  I have two RAM cartriges with it but do not seem like the
stock sounds.

So, it still seems that it is not accepting MIDI transfer to the unit.

Any suggestions?

Don't expect same sound as other synths, especially a Synclavier.
Edit/compare best horn sounds you have already and keep checking via
Google, oy, for best fit if you find/make nothing suitable.

Are you turning off the memory protect for internal? You may also have
damage inside not fixable by new battery, or battery is not put in
right or incorrect one.

You're talking about the manuals on the Yamaha site?  You need to
click on the links to the files with the right mouse button (or left
if you're left handed) and select "Save Link As" or "Save Target As"
or some menu item like that.  Don't open it in the browser and then
try to save it with the File menu.

You can configure Acrobat to do continuous scrolling in the View
menu -> Continuous.

I agree Acrobat sucks ass, but what can you do?


> I wish people linked alternate methods and obvious ways to save for

Acrobat is the cheapest way to go for putting existent documents
online.  If there was no Acrobat, there probably wouldn't be any
Yamaha manuals online.

I use version 5 of Acrobat.  It does everything the new ones do,
but without most of the bullshit.

You have to save it with the web browser as stated above, unless
I'm just misunderstanding your problem.

I haven't done this with my DX yet, but on some
keyboards, you need to tell the unit to wait for SysEx
data before you send it from the PC. Also, you need to
make sure that the MIDI receive channel is set to the
same one as used by the PC (usually 1).

I will have to do this with my DX - I've just replaced
the battery in that too.

Most important thing to check is the memory protect
is turned to off.If its not you will get no where,also
the dx 7 only recieves ,and transmits on midi channel
1 you have to set it up in the funtion control.if you
need step by step let me know.

Hey....thanks again.

I bought another battery.  This time it reads 3.0V on the display
which is an upgrade from the 2.8V and 2.9V of the other batteries.

I can set memory protect to on AND off and DX Manager still seems to
think that it is sending everyting ok.  "Long Syses Sent: 4103 bytes"
  "Midi output completed, OK"  It says that when the memory protect is
on AND off.

When I try to send DX Manager says, "MIDI long message error: invalid
sysex"

hummm.......????

Yeah, the DX Manager is just telling you that the /sending/ of the data
turned out ok, but the DX /receiving/ the data is a different story.
There's no direct way for a computer program to know whether or not the
unit actually received it, since DX7's don't send any kind of
acknowledgement when they receive data.


> When I try to send DX Manager says, "MIDI long message error: invalid

>

Have you tried going into the Options menu of DX Manager and trying the
different synth types (MKI, MKII) to see if it has any effect?

Matt Gregory

Can you elaborate a little more? Is the vocalist a
real person singing, or some piece of equipment called
a "vocalist" that has a MIDI port.

MIDI is a method of sending digital electronic control
signals between digital musical instruments, effects
and computers (though these days they are largely the
same thing once you take the cover off). It's bits and
bytes, and NOT audio at all.

The control signals indicate things like "this note
was pressed on", "this note was released", "the pitch
bend wheel has been moved this much", and the device
that's connected does whathever it's been programmed
to do with that information (including doing nothing).

So what are you wanting to do with the vocalist and
MIDI?

Is MIDI not really a hexadecimal protocol and not binary on/off
gigital? The patch-making and guts are digital but the MIDI signals
are hex. Avocoder sung into and signal converted to MIDI MIGHT trigger
a DX-7, maybe not, depending on Yamaha MIDI and the vocoder and other
things.
Rather a mess.

If you want to trigger MIDI from a non-MIDI instrument, you need to take the
analog signal (which is normally a CV [control-voltage] signal) and convert
it to a digital signal which speaks MIDI.

There are several CV-to-MIDI and MIDI-to-CV devices.  Paia has kits you can
build yourself, or you can find ones from Moog and other vendors which do
just great.

My IC15 chip slot has a 1/2 a chip in it.  It seems there is a chip,
but  not the "top" portion.

From looking at pictures of other DX7's (battery replacement pics) I
noticed that this slot is indeed empty on other machines.  What gives?

Can I take it out?
