Unfortunately, I had to abandon my plans for using ZenAudio live because there hasn't been an update for playlists, which is really the only way I could use it.
I love the idea of it, but I bought a Headrush Looperboard which gives me all of the basic functionality I need from a hardware looper, but not as much as what I could get from Zen.
I haven't given up on Zen, though. Would love to visit it again once the playlist functionality has been implemented.
Best of luck to you, and I'll be watching.
