EX800 scrambled patches

EX800 scrambled patches

2016-02-07 by pvanadrichem@...

Hi everybody,


My EX800 has been experiencing problems. Basically, from when I bought mine, it used to lose its patches occasionally: all patches would change into this nonsensical white-noise-with-square-wave-and-lfo jumble. Also, the midi channel was set to a nonsensical channel (f.i. H87). I managed by sending a sysex patch, which always fixed it. Now it seems to be getting worse: everytime I turn the EX800 off, it loses its patches.


Anyone had this or a similar experience?


Best regards and thanks for your input here!

The lithium battery is dead. Replace it.

No. Sorry, I should have said that: I did replace the battery, that's the first thing I did. Maybe the battery doesn't make contact?

This sounds similar to a problem I had with my Poly-800. If I unplugged it from all power sources for more than a few minutes, some (but not all) of the patches would get scrambled.

I was told that it was one of the memory chips. (It's the first chip in the series on the motherboard; I don't remember the number, sorry.) The guy replaced that, and since then, no other patches have been scrambled.

Unfortunately, I also can't seem to load anything from my tape, which worked properly before I had this $5 chip replaced. He didn't use the same, exact chip that was there, since they're not available any longer, he said. I'm thinking this could be my problem, but I hope you can get the chip you need!

Good luck!

Steve
