I am using an iPad pro with iOS11, in conjunction AUM I normally use app instruments and external synths coming in from the line inputs 3 and 4, all set to go out the main 1/2 outputs and then onto amp, speakers. What I want to do now is to keep this but also have some instruments set up to go solely to output 3 and 4. When I create a strip in AUM with a synth app and a routing out to of 3/4 or 3 or 4 only, I can't get any audio.
Is it possible to use AUM to route signals to the 3/4 outs like I am describing whilst also have other going separately out of analog 1/2?
If yes How should this be set in the iconfig mixer page? what I have now in the iconfig audio mixer is submix 1going to 1/2, one channel with input U1.1 and U1.2 another channel is receiving from U2.1 and U2.2 both are going out to 1/2. I tried adding out 3/4 here but it didn't seem to help much.
Thanks for your help.
