Loop Detect

Is the loop detector in the 4000 accurate? How about the temp detector? I've got a 4000 coming in the mail and I'm curious. I've been reading the manual. Seems similar to the 1k with jjos2xl. Anything I should look out for in the OS?

My appreciation in advance.

the dedector will just do the math and give you the tempo..
its as accurate as your sence of timing .. you count, punch in /out ..and set the beats..
