[sdiy] Odd MKS-70 Behaviour....

[gmuir at sympatico.ca]

Hi all,

A DIY repair question.... ;-)

I'm just getting around to cleaning up the SuperJX I picked up last summer, and as far as I can tell it is 
fully functional except for one ANNOYING feature.

Every time I shut the machine down, the MIDI parameters get scrambled. For example, the control 
channel becomes 1X (literally what the machine reads!!), and I get similarly odd results on both the 
individual A and B channels. While I CAN go through this little routine upon startup forever and ever, I 
am generally concerned that this might signal a bigger problem on the horizon.

So far, the only things I can think of are:

1. The backup battery is on the way out;
2. Bad RAM chip;
3. Partially scrambled software.

BTW, if I recall correctly I'm on version 1.04 (which I plan on upgrading soon in any event).

Any other ideas?

Cheers and thanks!

Gavin.
