Hello, guys.
 
This is the second time I'm trying to use the External Insert plugin with a Lexicon MX200 effects processor and failing.
 
It supposed to be a simple setup...
 
1. Connect one of the outputs of my audio interface to the input of the MX200.
2. Connect the output of the MX200 to an input on my audio interface.
3. Select respective I/O in External Plugin.
 
Why am I not getting sound/why am I getting feedback? What am I missing?
 
My audio interface in a Focusrite Scarlett 18i8.

Could you be specific and, looking at the whole signal chain, tell us which meters are moving and which ones are not.

Have you gone in to Focusrite mix control software and set up the I/O routing ?
And are you trying to track or mix ?

I can see the signal coming in on the plugin but the only sound going out when I turn up the input knob on the MX200, is feedback.

I'm trying to track. Record the dry/wet signal.

...I'm trying to track. Record the dry/wet signal.

 
In that case it won't work the way you are doing it. Anything in the track's FX bin doesn't affect what is being recorded in the track. You would need to use a different routing configuration if you want to record the wet signal from an outboard hardware processing unit.

Just to add. There will probably be more than one way of achieving what you are aiming at. But I am not familiar with your interface, so I will leave it to someone else to advise.

I think you need a double set of outputs on your sound card to do this.  1/2 and 3/4.  Use the 3/4 to rout out to external hardware, which will then rout back to 1/2, eliminating your feedback loop.

That was the case.
 
I had the output of 3/4 going to the MX200.
 
Should there be some sort of separation between 1/2 and 3/4, since 3/4 (headphones) is outputting the same signals as 1/2 (monitors)? Maybe that is the reason I'm getting the feedback loop?

Disable the input monitor icon in the track and use the record icon to give you meters?
