Just got mine today. I tried to import samples, but for some reason, the card wouldn't load them, so I just formatted it and tried again. Still no go. Guess I'll need to score a 404 later.

The 505 imports just fine but you have to format card in the 505 etc. I had some issues when i first got mine importing but once you figure it out it works fine. No need to spend more loot on a 404 if that's the only reason.

i'm jumping back on the 505 (got one coming in the mail) as i've decided it's my favorite SP. i've tried 303, 404sx, 505, and 606.
