a strange problem with MIDI OUT in my CASIO CZ5000 - anybody has a clue?

a strange problem with MIDI OUT in my CASIO CZ5000 - anybody has a clue?

2006-08-10 by mr_shtootzky

Hello everybody,
My CZ5000 behaves in a strange way when I connect to its MIDI OUT an 
interface which I bougt recently: SWISSONIC MIDI-USB 1×1 (you can see 
one here  http://www.thomann.de/thoiw2_artikel-185425.html ).

And now let me explain what the problem is about.
The MIDI transmission itself seems to work fine both ways. I even 
managed to load patches from PC to CZ with CZ Sysex Editor, although I 
am quite a newbie. The synth sends all messages to the PC and works OK 
as a controller too.

However not everything is OK. When moving pitch bender and modulation 
wheels you can hear (throug headphones and line out) some strange noise 
artifacts which correspond to what I assume is the mididi data stream 
being sent to MIDI OUT. Not very audible, but annoying and there 
shouldn't be any such noise at all. It is the same with the keyboard - 
only to hear it you have to switch it to "local OFF". Each key when 
depressed produces a slight "tick" in the audio, again hardly audible, 
but it shouldn't be there. 

It is strange, because all this happens only when the MIDI IN cable 
from this interface is connected to the MIDI OUT of the CZ, and what's 
more - it happens regardles of the interface itself beeing connected or 
disconnected from the USB port in the PC.

The other strange sympthom is when I connect the MIDI IN plug of the 
interface to the MIDI OUT of the CZ when they are both live, sometimes 
the CZ gets something like an impuls which causes it to light several 
leds on the panel for a moment and blink the LCD, like it gets a kind 
of a RESET or something? But once the plug is in it sets fine and works 
OK. Strange, isn't it? It shouldn't happen though.

I tested the interface with my other equipment: the KORG Poly 800 and 
Roland MC-303. Everything's fine. They both seem to work perfectly with 
the interface. 

I should stress that the above problems with CZ do not occur either 
when I connect it either to Poly or MC-303 with ordinary MIDI cable. 
They communicate perfectly. No noise artifacts, no resetting the CZ.

So both my CZ5000 and SWISSONIC interface seem to work perfectly fine 
provided that they are not combined together.

What do you think is the cause of my CZ's strange behaviour?
Is it the interface (some tricky malfunction, bad design? It's a cheap 
model but looks and feels very solid and has even a THROUGH switch.)? 
Should I return it to the seller for a refund then? Or is it something 
wrong with MIDI OUT in the CZ itself (this "resetting" might point to 
that)?

Anyway I need some clue and I would appreciate all good advice.

Best regards
Marcin

I have two CZ 5000 that begins to reset ( I hear a sound click near MODE
SECTION and the LCD and the lighs blinks and the synth resets to A1 preset
... sometimes its occurs repeteadly) ... and some days after the sounds
begins crazy :(

the two begins to have this problem after 1 month of using every day ( I
bought the first past year and the second two months ago ) :(


I bought the CZ 5000 service manual and i will try to find someone here im
Bazil who may fix them :)

Hi Patrick,

  My CZ5000 was doing the same thing when I first got it. In the 
center of the keyboard there is a brace that supports the top. There 
is a little rubber pad on this brace that keeps the boards in the top 
of the synth from shorting out on the brace or the keybed assembly. 
On my synth this pad was laying in the bottom of the synth because 
the adhesive had gotten old. Remove the top then use a couple of Ty-
Wraps to hold this pad to the top of the brace also make sure the 
brace isn't bent down because something heavy was set on it. Bend it 
up if it is. Voila, now the synth doesn't reset back to A1 and 
restart every time a button is pressed (or randomly). 

  Let me know if you need more help with this... You can e-mail me 
offlist if you wish. I have the Service Manual too.

  I'm not sure about Marcin's midi problem. It almost sounds like a 
midi feedback issue...

My problem with my cz 5000 is that after it begins to reset to A1 without
pressing any button ( it resets sometimes continuously , i turn off the
synth and it stops , but some minutes later the problem returns ).


Some days later the problem stoped and the synth begins to demonstrate other
problems like strange sounds , polyphony reduced to mono and no button
responds. i turn off the synth and turns on . The problem disapears for some
minutes.

These problem begins to apear after some days that a ised the Cz 5000 for a
long time of programing ( 3 or 4 hours playing with it without turn off )

Often a symptom that appears after a certain length of time is the result of 
something overheating.  Start by checking the power supply: check that the 
voltages are appropriate and without excessive ripple, and that nothing is 
blown or overheated.
