This was an interesting mix. Even though it’s just 2 people, they fill their sound by having a lot of triggered synth/loop sounds to their performance. When first setting this up, it was real obvious that there was 2 live people playing, and then canned synth stuff going on. I needed to make them sound all as one. I fed the synth through some light reverb, the same that I put on the vocals. This helped sell them as coming from the same environment and make the whole performance sound as one.
