Thanks a lot, Peter. I really appreciate the reply and information. All the interfaces seem very similar. This info is just what I was looking for.
Now, to figure out how to minimize the latency in both my iPhone 6 and iPad 2.
I performed a test in my DAW (Reaper) to measure differences in latency between Amplitube Windows, Amplitube iPad and Amplitube iPhone. For each test version I simultaneously recorded a direct signal and the output from each of the three versions of Amplitube I'm running. I ran all without effects, amp, or cabinets.
My approximate results for latency are as follows:
Amplitube (DAW): 22 samples
Amplitube iPhone 6: 564 samples
Amplitube iPad 2: 487 samples
While the amount of latency between the iPad and iPhone is negligible, like most people, I'd like to get the least amount possible.
Is it reasonable to expect a little less latency with iRig HD 2 because it uses the lightning connector as opposed to the analog input/output on the ios devices?
Thanks again for your previous reply,
