Playing along with an audio loop is much like playing along with an MP3, or Wav. recording.

Audio loops used in styles do not appear to have anywhere near the flexibility of midi based loops.

Midi based loops are incredibly editable....you can change the groove, the swing amount, the dynamics...offset notes...shorten or lengthen decay.

What real advantages do audio based loops have, other than sound as realistic as a recording? In actuality, midi loops are playing recordings too...they are playing samples (recordings)...in most cases, multi-samples.

If you record audio based loops...is the result a recording of a recording?

The technology for doing audio based loops, especially instruments that play chords (in a style) is still very limited...too limited, it seems to be completely successful.
