I've recently bought the kb37 and i can't solve the following problem.
I use cubase for recordings, and when i activate de monitor, latency is very notorious. I already check the kb37 tone direct's control panel and reduced buffer size but soudn system like "colapse" or starts making "click" sounds. The only way to make that dissapear and work correctly is with a larger buffer... and its not the reason why a bought my line6. Can't find a balance with latency, not even with 128, 256,512 etc
My system's charasteristics are
Intel(R) Core(TM) i3 CPU M 370 @ 2.40 GHZ
4.00 GB RAM
Windows 7 x32 bits
I use Ableton, not Cubase and I'm not a pro... But normally the latency issue can be solved inside the program and probably isn't in KB the problem.
I don't know WHAT you need to do, but try configure the in/out buffer latency on cubase preferences. it may work
