Well, since DrumPerfect and Auria are both developed for the IOS environment, I am thinking it should be expected that they work together. One is an industry leading DAW; the other is attempting to gain market share as a new and promising program.
Frankly, endless tweaking of settings and etc. is a profound turnoff. The goal is to not have to problem-solve. I'm sorry if that sounds spoiled or etc., but that is my level of expectation as a consumer. Because if what I purchase does not work in a 'normal' environment, that means I am a beta tester. If my money was taken first, before I was aware I was made a beta tester, that makes me feel like my time is disrespected.
Hopefully, the bugs are worked out.
