For those wondering how to actually send to guitar pedal and back, here is a step by step guide. The manual is a little rough…
Step 1 - Go to “com” and make sure your 2nd output is set to “Audio”. You can only set the output when your cable is NOT plugged in. Then plug in your cable after you set the output.
Step 2 - Make sure the 2nd output is going to the input of your pedal. Then take the output of your pedal and go to the input jack of the OP-XY
Step 3 - Click the Auxilary 1-8 button (1-8 button that looks like an audio jack)
Step 4 - Click Track 5 - which also looks like an audio jack
Step 5 - Under the OP-XY screen there are buttons labeled 1-4, click button “1”
Step 6 - Use the first rotary knob to select your input method, which in this case is the audio jack icon and then click the knob in to actually select it. The input icon should get brighter when active.
Step 7 - Use the 3rd rotary knob to select your input level and the 4th rotary knob to select your mix level
Step 8 - Now select button “2” from the 1-4 buttons under the OP-XY screen
Step 9 - Turn up each track with the rotary knobs that you want sent to the guitar pedal
Step 10 - You should now hear the pedal return on the tracks you just chose to send to the pedal
