...that sort-of fixed one of the issues I was having? But I still can't route audio into Auria via #AudioBus, which is a moot point because #iOptigan's IAA support doesn't seem to work anymore anyway.  

I wound up patching my iPad's headphone jack through a direct box to my interface's mic input, and recording iOptigan to my desktop. It seems like there *must* be some way of just capturing the system sound on an iPad (independent of the application(s) producing audio) but I haven't found it yet.

I remembered that I had finally installed the free license of #CubasisLE that came with my interface, so decided to try that out.

I can tell that even the LE version of Cubasis is quite powerful, but there is nothing intuitive about any aspect of the UI; I had to search the manual and/or the internet to figure out how to do pretty much *anything*. Incredibly frustrating compared to Reaper, which was what I mostly used before Auria.
