iTunes.
A couple weeks ago I experimented w/ running our click track and loops from iTunes. See the initial blog entry here:
http://bdivine.posterous.com/how-were-running-loops-this-weekend It worked pretty good, but as almost everything does, it had it's pro's and con's.
After mixing down the songs to stereo tracks in ProTools and importing them into iTunes, everything went really well. Our drummer fired the tracks from iTunes and we really didn't have any issues.
It wasn't until the following week when I went to put the tracks together for the weekend set list. We were doing a brand new song and so, like normal, I recorded a few loops and tracks for it. Again, I panned the loops to the right and the click to the left. Unfortunately when I went to "bounce" the file, I forgot that I had muted the click track while I was mixing the loop tracks... and since I was in a hurry, I didn't listen back to the bounced AIFF file.
When we got into rehearsal, the drummer pulled up the track and it started running. The pads and loops sounded fantastic, just as they had the week before, but there wasn't a click running alongside it. The lightbulb went off in my head and I realized what I had done.
The biggest problem w/ running tracks from iTunes or any other 2 track set up is that you're stuck w/ whatever is in the tracks at that moment. You can't adjust tempo, volume of individual tracks, or even add tracks quickly.
The next day I went in and built our worship set in Live which worked beautifully as it usually does.
Here's the practical lesson I took away from this:
When working in worship you have to BE FLEXIBLE. While iTunes is a great tool and can be used.... for us it's not the best way to stay flexible in our worship experiences.
I'm always looking for new ideas on running loops, however the one thing that I don't ever want to loose is flexibility.
