I want to record my live dj sets flawlessly. I have been told to try the ikey. Can I just use the sp 404? Will the sound be high quality and how can I convert it onto my lappy? I use serato and ableton.

- what do you mean?
..to record a flawless set you will have to avoid mistakes ;P
No, but what is the case - you can´t record straight to your laptop ?
Depending on you mixer you can record it from some alternative outputs to a seperate recorder.
. Or?

I use minidisc for that matter. It has some sort of built in limiter or smth, helps straighten levels abit. The quality is not perfect, but that's not a studio mix it's a mix from a gig so why bother =]

the og is roland propriority. the sx is wave 16bit/44.1khz (i don't heve that but it's not straight out wave, i think you still have to convert it).
the og sounds good to me.

You just need an rca->1/8" stereo cable to plug into your computer's line in (if it has one)..
then just download audacity and record...

sounds fine for recording mixes unless you are a famous person making a commercial release. In which case you already know how to do it anyway

i used my 404 as my "tape recorder" now i use a 606.. i record myself on other gear into the 606 and export out to the card then drag to the pc. same thing i did with the 404... you can use effects too
