Hey I hope someone can help me, I have a loop station Boss-RC30, and an audio interface Scarlett 6i6, I want to record a song with three inputs (Vocals, Guitar and Keyboard), while also using the RC-30, but I'm not sure how the set up should be so that the audio interface would record everything I play with the instruments and the loops I do while doing this song. Should all the instruments be plugged into the interface and then the Boss RC-30 plugged into an output of the interface? Would the interface record the loops I'd do with the loop station?. In case I don't make my self clear, my idea is to record a song as some YouTube videos where someone covers a song using instruments and also a loop station to have loops through the song, and all the play is recorded so they have the soundtrack for the video, I hope someone can help me, Thanks.
