You are using two sources but you don't have the pedal in dual source mode. The "crossover" mode that you are using here is for single source like a single pickup. Your microphone is being ignored by your pedal setup and I can hear there is no microphone being blended in
I used this live with a dynamic mic in a quiet setting,about 40 people. Dialing in the balance at home,discovered its best to use TRRS connectors. Aura in series with pickup yields satisfying results.
Hmm. Recently bought a Sire acoustic, with a piezo and magnetic pickup. Comes with an outboard mixer box for summing the two pickup systems, and i have to say, does a lot of what this seems to do, for £300 all in, i.e includes the guitar itself. Now your demo sounds fine, but i can't help wondering if the Sire package gets surprisingly close for a lot less money. You should try one out.
