I dunno what's wrong. It's gonna be a mess to explain but I'll try cause I'm really pissed by that shit.

I save a pattern as a backup. Now I wanna load that shit / -> copy pattern.
I can load the pattern but just 4 or 5 times. After the 4th load the LOD screen stops -> no button reaction at all. I do a "restart" of the machine and it shows "Err". Another restart and everythings seems to be fine but wait the fucking bad thing is that Bank A + B are totally empty (samples + pattern are gone into some kinda black hole). I have this trouble already for a while and the strange thing is that whenever this loading err comes up, bank A+B are like they were before backing up the first pattern. Know I mean?!
Of course I tried different cards but nothing went better. Expierences? Is it the machine? I never pulled out the card while the machine was running or sth. like that. Doing the copy pattern trick without a pc is quit dangerous for me now... DAMN!
(Today I was doing a lil beat at work during the lunchbreak and I was like "why this must happen now?!". )
I was really close to fix my 404 the juxt-way. *bam bam moow*
Hopefully there is a better way?

Try loading a new copy of the O.S. , when it comes to the 303/404 there is a ghost in the machine and that's best I can explain it since they all do it but in a slightly different way or at random times. Maybe it's the same ghost that makes a beat slap so hard out a little black box. It's the whole good with the bad/duality in life that these samplers reinforce, oh and impermanence 'cause I know we've all lost that one beat that you'd kill to have again.

but where can I get a new OS?

You'll need a card reader as well.

Thanx man. I'm trying this now...

*edit

Sh*t .. I already have the latest version... 1.04



2nd edit
After I checked the version of my 404 (holding down mark while turning it on) all that shit from bank a+b were back... Crazy...

The ghost smiles... =)

ah yeah... I understand... but what can I do to avoid that shit?
Calling the ghostbusters?
Is it possible to "downgrade" the 404?

sure, it's called a mpc.

zing!

Even if you have the latest O.S. sometimes a problem occurs which can fixed by installing a fresh copy. When my pc was my main computer I kept my files on redundant external hard drives and only Windows XP on the internal drive so that I could reinstall if I get hacked and not loose data. Now I use a macbook for recording and there aren't to many malicious scripts and viruses written for OSX.

I tried that update thang but it didn't helped...
I can't do that copy pattern shit without the pc anymore... it's just to dangerous (loosing samples and stuff) THAT SUCKS!!!
Making beats outside of the lab is just impossible now.

good bye internal memory...
