So I bought a US-224, not knowing that it's just about useless in OS X. There are beta OS X drivers, but I can't find good multitrack programs that work with the US-224 for OS X. Do they exist? At the moment I'm using Spark ME and the Ableton Live Demo, but neither work with the controls on the US-224, they're just capable of getting audio through it. Are there any good OS X audio programs available? thanks.
