Screeching noise when mixing with 'outboard gear' Audio Interfaces

Screeching noise when mixing with 'outboard gear'

Hi All
So I've been experimenting with running line outs through guitar pedals then back through line ins. I'm using a Scarlett 2i2 and this is working perfectly using a Boss DM-2 delay pedal and also when running through an amp. However, when running through my multi-effects pedal (Boss ME-25) I get a really loud screeching sound whenever I apply an effect. The only one I have succeeded in achieving is very (and I mean VERY) low levels of reverb.
Can anyone help a poor (as in lack of money as well) Gearslut out?? What am I doing wrong?
Can provide any other info needed I just don't know what else to put.

N.B. - I am running a signal from my DAW through the Right output of my 2i2 and then running that signal back into my DAW through the Left input.

Seems like you've got a feedback loop happening.

I'm guessing your return track in your DAW is also going through that "right" output. Make sure it's only going through the left.

It's also possible you may not be able to monitor at the same time depending on the routing of your interface.

If you are coming from an output of the Scarlett back to an input, make sure the "direct monitor" switch on the front of the i2i is off or you can create a feedback loop.
