1. random patch generator
2. better clock timing
3. insane arpeggiator options
4. midi improved
5. others...

cons:
1. lose tape dump/load functionality (slightly BD if you have tape back ups)

You can still boot up in Roland mode and use the tape interface (if you must)...

Do you have a voltmeter? What voltage does the battery measure? Did you install it in the right direction?

i de-soldered the old one, and put the new one in (yeah its in there the right way) then i couldnt figure out how to solder the new abttery in there, so i clamped it in place so its touching the two metal prongs.

is there a certain way to re-solder the battery in? i tried putting a bit of solder on each tip of the prongs, but i could only get one side to stick.....but as of now, both sides of the battery are in contact with the metal prongs to the main board.

Sounds like it could loose contact in which case the memory would be wiped. You should have a new battery with solder tabs and soldered it in. What voltage do you measure at the battery check connector?

Can you attach a hi-res picture of the work you did? When you solder in a new battery be very careful in how long you hold the iron to the battery legs. If its too long, it could explode.

hello! sure i wil attach one in the morning, just lugged the J-6 back to the studio space.

i held it moderately long to the battery legs. i couldn't get the to stick! no explosions though. i placed a bit of solder in between the leg and the battery, but i still coudlnt get them to stick. in the end i place a rubberband around the legs, holding the battery in place between the legs. i know thats not the legit way, but i ran out of ideas...

I really recommend installing a battery holder any chance you get. I know I sound paranoid, but better safe than an exploding battery.

Well here is mine. It obviously looks like it was replaced at some point, but I'm pretty sure it wasn't a CR style battery. Are you sure you replaced your battery with the same CR number and not just another 3v? Because the CRs come in different diameters and thicknesses as well as voltage.

Don't apply your iron to your CR battery.. I'm sure that would exploded in a few seconds.

it looks like this:

when i took the old battery out, it had two metal protruding prongs. i kept those in and yanked the old battery out. should i put in all NEW prongs all togeather?

Hmm... are you asking if you should touch the prongs together? In this and previous messages it sounds like it.. If you do that, it will short out the battery (and cause it now to work). I'm sorry if I'm intrepreting you incorrectly.
