[PD] using pd live (sans computer/laptop/raspberry pi)

[Aaron L.]

Wow.

That pdf is beyond awesome, Dan.  On many different levels.

Question about this part though:

(and I guess my previous question still remains unanswered....)

I want to take line-level (which is low-level impedance, correct?) back to
instrument-level so as to use the guitar amp.

So how does one get one's guitar "out" of the UDOO and back into the guitar
amp?

I'm assuming the only way would be to take the stereo out from the UDOO and
plug it into a DI running in reverse and, finally, back into the guitar amp.

But it doesn't sound like that's what you're doing specifically.  It almost
sounds to me like you go into the 'house mains' sans amps on stage.  Or am
I missing something (wouldn't be the first time).
