HX Stomp Routing Help Needed

[macnevine]

I am confused when I read the HX Stomp Manual re: USB signal routing.  My use case is this.  Guitar left mono in goes to the Stomp.  Guitar left mono goes out of the stomp.  Check- that works in the obvious way- I hear the stomp effects and I can play with levels etc...

 

Now I connect my IPAD with the camera connection kit to use with the HX stomp as a USB interface for live use (not on a computer for recording).  I use AUM or audiobus (IPAD signal routing app) on the IPAD. In that APP I select HX STOMP USB 1 & 2 as the input.  I then drop the TONE STACK app into the signal chain.  I then select HX STOMP USB 1 & 2  as the output in my IPAD routing app.  

 

Where I am confused is this.  I mainly use Tone Stack for modulating effects to free up some blocks on the HX STOMP.  My USB signal was weak so I had to go into the HX STOMP and turn the Global setting Pref. "USB In 1/2 Trim"   up a bit.  That seemed to give me a good mix of tone stack effects with HX Stomp effects.

 

My question is (I am not sure I understand which signal comes first or last or if it is merged etc..)

 

1.  Am I hearing 2 separate signals - i.e. HX is sending its signal dry to my Tone stack amp and also sending a separate signal with its effects to one of the USB outputs on the HX stomp.

2.  Or is the final output of HX stomp being sent first with its effects and then being routed internally to the tone stack app and then the tone stack app is then merging everything to the left mono output on the HX stomp.

 

It is hard for me to know what is handling what as it relates to the USB interface.  I read something in the manuals about USB out 1 & 2 carrying the dry signal but to reroute using outputs 5&6 etc... very confusing to me what all off these outputs mean.  I did not know if anyone could explain this in layman's terms?

 

 Maybe I am overthinking it. My tone sounds good the way I have it routed.  When I select a dirty preset on the HX stomp it seems like my delays on my IPAD sound clean and not muddied and my tone stack Chorus sounds pretty amazing.

 

Thanks for any thoughts about this topic.
