Looks like the lockout thing was a driver issue because it doesn't happen anymore... ALL the keys on my USKOC work fine with a Super Joybox 3 (and they got cheaper too by the way) but at least for me there's still a little lag.... I have to put offset to like a -14 on BePachi-music. I can still play for the most part though. Before, I couldn't even play.
So yeah, works pretty good.
Man, you dug this up out of the darkness for real yo!
Hmmm... I got a parallel one and it DOES NOT work... BUT I heard DJ Dao has one that DOES work PERFECTLY... but I don't know how to optain one... If he's selling, I'm totally buyin'.
Depends on your motherboard. My PC at home can only go up to 500 Hz without problems, my PC here can do the Super Joybox 3 on 1000 Hz. If it's a US controller, though, 250 Hz is your limit I'm pretty sure.
