Internal Feedback Loop

Hello All,

I’m trying to create an internal feedback loop using a send as (almost) described in this old Joe Filbrun video here (ER-301 Internal AUX Channel - YouTube)

Basically i’m just trying to feed the delays output back into itself

one top level mixer with an added send control as described in the video above
two mixers before the delay
one fed by the dry signal
one fed by the send i added to the top level (locally routed from delays output)

Seems like it should be simple but for some reason audio just cuts out when i open the send.

Am i missing something?


When you open the feedback mixer/VCA, what happens to the audio on the scope at the output of the delay unit ?
