I often record a standard 8-bar progression and leave it in there unless I feel like changing it. It's amazing how many songs you can use it on.
I do wish you could store a few of them for use at any time. Of course you COULD do something like that simply by recording styles of the proper length, but I don't. Yet. I just had another brilliant idea.
I'm sure glad this is my last night off until Sunday.
