Can't use Flex Time to fix simple drumming errors
I can't get to grips with Flex Time. I'm trying to fix some simple drumming errors where the drummer was a half beat late on some accents but when I try to turn on Flex Time it moves all the beats out of time before I can begin to adjust anything. It doesn't seem to matter what mode or quantisation I set.
I don't find the manual to be of any help, can anyone suggest anything?
