10 About Overdub Recording and Monitor Mixing

18

Much of the popular music that you hear today is created using a method called “overdub” recording. Overdub recording allows artists to record their music while listening to previously recorded parts of the song. For example, a vocalist may record his or her parts while listening to the previously recorded guitar, bass, and drum parts in his/her headphones. This method is popular because each recorded part is completely separate from the other parts and can be more easily edited and mixed into a “polished” song. For example, if the guitarist is not happy with the solo, it is possible to edit problematic notes, re-record the entire solo, or even “splice” together the best parts of multiple takes to create one seamless performance. This kind of detailed editing is generally not possible with “live” recording situations in which all sounds are captured at once.

To record overdubs, each artist must have a monitor or “cue” mix sent to his/her headphones. This mix contains the previously recorded tracks combined with the “live” signal that is being recorded. For example, the vocalist would need to hear the guitar, bass, and drum tracks along with his/her own vocal performance as it is being recorded into the computer.

Fast Track Ultra 8R allows you to create up to four stereo monitor mixes using the first four tabs of the Control Panel. Each tab controls a stereo mixer with 16 inputs (eight hardware inputs plus eight outputs from your audio software). The “Software Output Signal Routing” section of this User Guide covers this topic in greater detail.

Each tab routes signals to a separate pair of outputs as shown in the following table:

routes to analog outputs 7/8, select the “Monitor 7/8” tab.

2.Adjust the level faders for the hardware input and software return channels to create a comfortable monitor mix for the listener.

•The eight channels on the left side of the mixer represent the “live” hardware inputs. For example if you have connected a microphone and guitar to the first two inputs, signals from these devices will appear on channels one and two of the mixer.

•The eight “Software Return” channels correspond to the outputs of your audio application.

•The last two channels on the right side represent the monitor mixer’s master outputs that are sent to the mixer’s associated hardware output pair (on the rear-panel of Fast Track Ultra 8R).

Keep in mind that this mixer is for monitoring purposes only. All signals received at the hardware inputs are also sent directly to the recording application without being altered. The Monitor Mixer receives duplicates of these input signals to allow you to create a near-zero latency monitor mix.

Changes made to the monitor mixer do not affect your recordings (or your audio software), since the Monitor Mixer’s output is not actually being recorded.

For example, if the singer would prefer to not hear guitars while recording, the guitar channel of the singer’s monitor mixer can simply be muted without affecting the recording application in any way.
