Audio input bug?
First off - I'm a new owner of a Deluge so pardon any ignorance.
I get what sounds like an overloaded audio input when I plug my guitar modeler into the input on the Deluge. However, if I unplug the right OUTPUT plug on the deluge and plug it back in, the problem goes away. It's not a level problem as when the plug is pulled and inserted, the problem goes away.
Note - the Deluge 1/4" outputs go to a Scarlette audio interface.
