How can I play audio on a Mac (10.11) in a 3d party software instrument (eg. Arturia Synth), piping it through the
built-in line out, into an analog effects pedal, then record that as an
input through something like a Scarlett 2i2 without getting duplication, feedback, and extra noise in Logic Pro X; all in one shot?
When I try it I get a reverb/echo-like feedback loop when the software instrument stops.
