Because each track requires a whole channel strip.
I'm confused about this.  Are you saying that each track requires it's own output channel?  They can't share?  If my interface only has 4 channels, I can only use 4 tracks?
In the app, there's main output and 3 auxiliaries, all stereo, so that's 8 channels.  Could there be 8 mono tracks?
Also, since I've watched Scott Uhl's videos, I've been trying to figure out how I will use the app.  I'm super impressed with both the app and your helpfulness here in the forum.
