I'm new to using this. I have two mics set up both at the base of the piano, when I create a stereo audio track, only one audio track comes up instead of two, then when I type in 2 under 'number of tracks' it creates 2 audio tracks but I can't record enable them both at the same time. I also can't pan one mic to the left and the other to the right like I've been shown to do. Any help?
