Simultaneous multitrack recording using Apogee Duet and GarageBand
So I recently switched over to my iPad from a Mac once I learned about Audiobus' ability to run multiple apps simultaneously and connect them. As well I purchased an Apogee Duet and have been really pleased with the sound quality and the ability to record simultaneous tracks on an iOS device. Everything has been going pretty smooth and I'm getting used to all of my new equipment but I keep running into one drawback, recording simultaneous tracks into GarageBand going through Audiobus. I'm able to record both my guitar and vocals simultaneously, and Audiobus is keeping them separate in the regard that Amplitube, the app I'm using for guitar, is not adding any fx to my vocals, or vice verse with IK's vocal app. The problem lies when I go to record them into GarageBand, even though I have them running through separate channels with the duet, GB records two tracks simultaneously, but they are both identical, containing both instruments and making it impossible to edit separately. I've played around with a bunch of different configurations but let me layout what I'm doing so you can correct me if I'm wrong.
In Audiobus, I create one stream with system audio as my input selected to channel 1, which is my guitar input corresponding with ch 1 of the Duet. I then add Amplitube as my fx, and GB as my output.
I create another stream with system audio ch 2 as my input, which is my mic input corresponding with the Duet. I add IK's Vocal Live as the fx and again GB as the output.
In GB, I create one track selected to ch 1 and one to ch 2. I can tell that it won't work right away because when I go to monitor them, both meters react to the instrument or mic.
*** I have tried using Amplitube and vocal live as the input, which works find stand alone but when they are both open I get guitar distorted vocals and vice verse with the guitar. Am I doing this part right. I don't notice many people using system audio as the input on most of the Youtube videos I have seen?
Well I look forward to hearing what you guys have to say and I appreciate the help in advance.
Also, any recommendations on an app besides GB I'd be open to.
