Hello dharris3112 and welcome to the forum.
I'm slightly confused - Pod Farm is a plug-in, isn't it? If so then the latency will be set in your plug-in host / DAW (Cubase?). And, then, that latency would apply when you use AT4 as a plug-in.
Or did you mean the PodFarm standalone program? If so, then, given that the UX2 supports latencies less than 256, then those choices should be available in the settings for the AT4 standalone program too.
As this is primarily a user to user forum, someone-else may chime in. Meanwhile, the best thing to do is raise a Support Ticket, here:
