Obnoxious default. There shouldn't be a default.
There isn't a default for length, SONAR guesses and sometimes gets it right, sometimes not (usually when not, it's double the beats). However, I'm pretty sure the guess is based on the assumption that the loop will be a "binary" number of measures - 4, 8, 16, 32, 64, 128, etc. Those are the loop lengths in 99% of the sample libraries I've used, so at least it's a pretty logical assumption.
