Seeker,

Loops with specific key identifier in the name usually have tempo and key signature information embedded in the loop to help software control tempo and pitch better. Another reason may be because the loop is presented out of context. The loop you're looking at may be just one of a series of loops and the key identifier in the name describes the loops place in the series.

There is no standard loop length. Loop length generally is described in measures with one or two measures being most common, then half or four measures a little less common and eight or more measures rare.

Commercial loops are normally sample accurate to avoid drift over time through repetition. For each second of audio there will be exactly 44,100 or 48,000 (or whatever the sample rate is) samples.
