its quite simple, I use it daily since i bought it 2 years ago, I also have an UX2. Basically the toneport is like any card, you will get only the DI. If you want the distorted sound, you can put the podfarm plugin on the track. Or to record the basic way, you have to open podfarm besides your DAW, so that it produces the processed sound, and find the way to route podfarm sound output to your track in. I remember when I was doing that it was often as simple as hitting the record button of cubase because it was recording the processed sound with no need to tweak the routing, don't remember of having anything to do.
So if I'm well, you should be able to record the sound opening podfarm BEFORE logic, or if you have the plugin just put it on your DI track.
