is there any warning before the internal RAM BATTERY goes out?

[chimney chop]

...or does it just fail suddenly.

just got the Indigo 2 and the "warranty void if removed" sticker is intact so i'm kinda worried i'll lose all my saved patches soon if the battery has never been changed.

the manual suggests replacing it every 3 or 4 years

anyone?

is the 3 or 4 years the manual suggests an underestimate of how long the battery lasts or is that pretty accurate?

any info would be greatly appreciated from those who have had to change their battery.

thanks!

Don't be too paranoid about your battery, that said... stay vigilant in checking it.

Things can go badly real quick. My old KORG POLY-61 went from being a nice functional poly synth, to a retarded turd with corrosion on the main PCB in a matter of a few years.

how do i check it?

The Korg Poly 61 is and has been NOTORIOUS for that happening and that is *not* a typical result of a battery simply needing changed in any synth. With a fully functional synth O.S., you will typically get a warning on screen upon power-up of "low battery warning", giving one time to sort it in a reasonable amount of time.
Just as it is pragmatic to back-up your computer DAW projects/files onto an external HD, it's good practice to save your precious patch and multi-set-ups with well-labled seperate folders containing sysex dumps in say the rare event your studio cat whilst on a catnip buzz runs through your cabling, causing unexpected power disconnect! Trying to say good practice to not wait until a battery change to do back-ups.
Both warranty sticker seals are still intact on my Virii KB and KC and know they have never been changed and still doing fine.
It would actually be fitting for a future Virus Synth to be fitted with plutonium battery, reflecting their namesake and call it Virus Half-Life, with optional lead shield and lead-waterfall action weighted keys!!!

Not tryin' to cop out, but ask Access directly for details about battery maintenance. They should be able to help, hopefully.

will do!

would still like to hear from anyone who's had their virus battery die and/or had it changed.

Hi, you can see the battery (a standard CR2032 lithium flat, disc-shaped battery) in my re-potting thread. http://infekted.org/virus/showthread.php?t=31443

For example, you can clearly see it here, in the centre, along the bottom.



Looks like it's just a simple clip holding it in place, no soldering needed.

BTW, I have an old Virus Indigo v1, and I haven't needed to change the battery yet. The same with a 15 year old Korg Trinity which has the same type of battery.

I think the standard Virus hardware warranty only lasts 1 or 2 years, so breaking that seal wont affect you if it's older.

ah, good to know. guess i won't fret.

had a jp8000 battery go out on me which is perhaps why i'm a bit sensitive.




by the way, i've been mulling over the pics of that source post of yours.

from the looks of the innards seems like adding wood cheeks wouldn't be too hard at all.

might be neat to give it a Sequential Circuits Prophet vibe.

ever thought of doing that to yours?

wondering if it would compromise the structures integrity.

do the aluminum sides seem to play a large role in the strength of the frame?
