Just get a card reader and dump your files to the PC to back them up. Delete the files, put the card back into the 404 and format. I've got a ton of mem cards, but usually only use one and wipe it fresh when I start a new beat.

Reverse the process when you want to load up an old track.

This'll sound mad ignorant,but I have no idea what a card reader is,lol. Obviously I've seen mad people talk about this stuff but I've never looked into it. Might have to do that.

real similar to the one i have, that one costs 11 bucks, mine cost 10 at big lots

ya a.D. you can get them for really cheap. the on van nostrand posted looks like it can read 4(+) cards so that's an all in one. I have a cheap SD card reader (as you prob know SD is the card the sp uses) that was like $5. It's well worth the investment.

I'd love to be as organized as some of you guys, it'll happen in time. definitely wouldn't mind having a whole card of drum kits. haha
