Patches and discussion for Ensoniq VFX family

I have changed my battery twice, the first time I changed it to a
socket so I could just swap out the battery when it went bad.
Alas, I had to send it in for something, it is so long ago I don't
remember what, they swapped out the mb so I did not have the socket
anymore.... 
So I had to redo it when the battery died again.
If you can find an old computer mother board with a battery socket to
remove, it works great.
It was not very hard to do.
however it did take a little while.
If i recall correctly.
Back up your presets... before, although if your battery is dead you
probably already lost them.

Unpluged ... obviously...

Keep track of your parts.

>allen wrench on the hinge top, I forget the size, I have the correct
one taped to the vfx.
>remove keyboard. As, long as you are there you might as well clean
the keyboard pad contacts and landing zone for the pads. I just used
some alcohol and qtips.
(I don't remember this, but I think you need to remove the springs and
totally disassemble the keyboard (you end up with a pile of keys, pay
attention on reassembly...)to clean the contacts... such vague
memories...)
>remove board with battery on it.
I think this has a bunch of plastic stand offs that you have to
squeeze... 
turn the board over, pull the old battery after heating up the solder
contacts with a hot soldering iron.
Remove.
Install new bat.
reassmble.
Send the old sysex back to the beast.
Rock out!

If you have the keyboard calibration error you can fix it while you
have it apart.
Check the file section.

There is my 2 cents.
It probably takes an hour (uninterrupted), if you have all your tools
and supplies ready to do it all.
Cheaper than sending it in for sure.

Like the other reply said - if you can solder a plug or a cord you can
do this.
