I recently installed a new audio interface to my comp. it isn't the ux2 line six, for which podfarm was made. Can I still use podfarm without having the ux2 hooked up?
Usually the UX2 acts as an authorization dongle, and has to be plugged into the machine for PodFarm to work. You don't have to actually use it, though. Just leave it plugged in, but use your new interface for audio I/O. It should work fine.
If that's not acceptable, the standalone license for PodFarm Standard is only $100.
