Slightly offtopic, but it's a shame looking through this thread from the start and seeing all the dead TinyPic links. So much lost...

sorry for stupid qustion but what battery do?
what if u take battery off the music still come out?

it holds the settings that are useful in a studio environment
ie you might want to use SC-55 for only certain midi channels - the battery will hold that setting
for retro-gaming use the battery is not needed - you will get a battery-low message on startup but other than that everything will work like we want for games

Just opened my Mk I and a tiny leak from the battery contained by the plastic housing, as some others have found.

No battery low warning message for me beforehand.

I've left the slot unpopulated, working fine.

Thank you for the warning!

Today I bought a Boss DS-330 for very cheap and opened it up to change the battery, which did not leak over time.

Because it came without the adapter and I wanted to test it I went to the attic and dug up my SC-33 to get its adapter and I heard an unnerving rattling inside this SC-33.
After opening it I found 2 surface mount capacitors going around loose inside the cabinet. They have leaked and came off the board, leaving trace damage of course.
Since I don't have these caps laying around I took some regular ones (47uF 10V, originals were 47uF6V), cleaned the board as good as I could and soldered those in place.

Luckily it still works but I might have to open up all my midi devices to check on this before it's too late?

yes harsh conditions have a disastrous effect
I hope Salient you also neutralized the capacitor acid with something like vinegar/lemonjuice - cleaning with IPA alone is not enough

Yep, I used vinegar and after some bubbling away I cleaned everything again with IPA before soldering in the new capacitors.

Hopefully just an attic problem but a good heads up, thanks.
I'd have so much more space in my house if the attic wasn't such a high/low temp/humidity risk...

These particular capacitors from around mid-90s japanese equipment are all failing, basically a form of capacitor plague. Bazillion video cameras, VHS machines etc. are dead because of them... If they haven't leaked yet, they're going to...
My Roland RAP10 is going to get new capacitors, it already has few that were leaking (all removed now and waiting for new parts). Friend's RAP10 had some actual damage from these capacitors already. Ticking timebombs...

There doesn't appear to be a battery in the MT-32 old or new versions, according to this photo I found.
