Hey Kevin,
I was actually thinking of more than just chord progressions, sorry about that. I like to play loops, produced with a full band or whatever--in different styles to give me ideas for how to treat a lyric. The loops I have just play the same chord over and over. I have loops in several different styles--pop, rock, country, blues, ballad, funky, hip hop, latin, reggae, spacy.... But every one of them is very short, so it's just an extremely short snippet of the style that plays over and over and doesn't go beyond one chord. I'd like some that go through a variety of chord progressions.
Yes, I do use my guitar to work out chord patterns for songs, once I've gotten an idea of the kind of treatment I want to use. And I don't always use loops, but sometimes, when I have a really hard time coming up with a good idea, then listening to a variety of loops in different styles is helpful.
Now that I have found a bunch of loops online, I don't know how soon I'll buy any. There are so many, and the selection is so confusing. It would be nice to find an extensive library that includes a wide variety of styles and chord progressions.
Plus, I keep forgetting I have other sources--SongSmith, for instance, and two keyboards that both will play different styles for me. With those I have to come up with the chord progressions myself, but that's the easiest part.
Thanks for asking!
Vicki
