The stinger for me in the audio loop/guitar mode debate is, okay, let’s say you’ve got some absolutely AMAZING sounding guitar parts in styles using the loops. But you’ve got limited chord choice. And you’ve got a huge collection of legacy styles without the loops.
So now you’ve got a huge jump in quality of backing between those audio loop styles, and everything else you need to play. One minute you sound great, the next minute, you don’t. And there’s nothing much you can do about it. Other than stop playing the tunes and styles that force you to use the MIDI guitars. Or stop playing the styles that show up the rest of your styles.
Consistency… that’s what you get with a well developed guitar mode. Your old styles sound as good as your new ones (as long as you assign the Parts to the best new sounds and kits) and ALL your new styles sound equally good.
As a performer, that’s what I’m looking for. I don’t want to blow everyone away one style and be Ho-hum the next. I don’t want to start substituting simpler (wrong) chords just so the arranger doesn’t jump to a mismatched MIDI guitar part for that chord it hasn’t recorded.
Consistency…
