In aeons end we often have three or more guitar layers going on, but we’re actually only two guitar players. To cover that, using backing tracks was essential from the very beginning of the band. Additional guitars or synths usually get exported from a song writing project as a stereo .wav-file. Later we import those stems into our live project in Logic.
The final step is dialing in the level of the individual audio files. Since we use Logics built-in normalize feature, the imported audio files usually get set to -23 dB LUFS. After setting the right pre-fader level, we typically adjust the track volume via automation. As explained in part 1 and 2, live guitars and backing tracks share a stereo analog output on our output panel, so after recording a new song directly in the x32 mixer, setting the appropriate levels is quite easy. We’re listening to the recording on studio headphones, IEM-headphones and also our PA system to make sure everything is set the way we want.
