Panning Individual Tracks: Logic's Bus Effectiveness

Panning is a critical method for saving time, energy, and computer resources when working on large projects in Logic Pro. It allows users to treat groups of signals as one, applying audio effects to multiple tracks simultaneously. However, issues with panning in Logic Pro have been reported by users, who have found that panning is entirely controlled by the bus, resulting in a loss of individual track panning. This problem has been attributed to mono EQ on a stereo bus, certain plugins, and other factors. To resolve this issue, users have suggested creating a new bus, ensuring the Logic native pan knob is centred, and using the Direction Mixer plugin.

Panning buses in Logic: Logic offers three panning settings for buses—Post Pan, Post Fader, and Pre Fader

Panning is a feature in Logic that allows you to adjust the stereo positioning of your audio tracks. This can create a sense of space and depth in your mix, making it sound more interesting and immersive. Logic offers three panning settings for buses: Post Pan, Post Fader, and Pre Fader. These settings determine how the audio signal is routed and processed, affecting the overall sound and stereo image of your mix.

Post Pan:

Post Pan is the default setting in Logic. When you use Post Pan, the audio signal is sent to the bus after any panning and fader adjustments have been applied to the original track. This means that the panning and volume settings of the original track will be reflected in the bus signal. For example, if you have a guitar track panned hard left and send it to a reverb bus on Post Pan, the reverb will also be positioned hard left in the stereo field. This is useful when you want your effects to follow the panning of the original track, creating a cohesive and natural-sounding stereo image.

Post Fader:

Post Fader sends the audio signal to the bus after the channel fader but before the panning adjustments. This means that any changes in volume will be reflected in the bus signal, but the panning will be independent. Using the previous example, if you have a guitar track panned hard left and send it to a reverb bus on Post Fader, you can then pan the reverb independently, creating a panning echo effect. This gives you more flexibility with your effects placement in the stereo field.

Pre Fader:

Pre Fader sends the audio signal to the bus before any fader or panning adjustments are made to the original track. This gives your bus complete separation from the original track, as if you've created a copy. Even if you mute or change the volume of the original track, the bus signal will remain unaffected. Pre Fader is useful when you want to create parallel effects or when you need a consistent signal level for processing, such as in headphone mixes.

Understanding these panning settings will allow you to make informed decisions about how to route and process your audio tracks in Logic. Each setting has its own advantages and applications, depending on the creative and technical requirements of your project. By utilising these panning options effectively, you can achieve more precise control over the stereo imaging and overall balance of your mix.

Individual track panning: Panning a normal track is straightforward, but panning individual tracks within a track stack can be confusing

Panning a single track in Logic Pro is a straightforward process. However, panning individual tracks within a track stack can be confusing, and the results may vary depending on the plugins used.

A track stack in Logic Pro involves grouping related tracks into a single, unified stack. There are two primary types of track stacks: Folder Stacks and Summing Stacks. Folder Stacks are used for organisational purposes, allowing multiple tracks to be grouped into a single container. On the other hand, Summing Stacks are used for routing multiple tracks to a designated bus, with the output directed to an audio subgroup.

When it comes to panning within a track stack, the results can be inconsistent. Some users have reported that panning the main stack will affect all the tracks within the stack, but panning individual tracks within the stack may not work as expected. One possible explanation for this behaviour is the output configuration of the track stack. If the track stack is set up as a summing stack, all the individual tracks' outputs are combined and sent through a single stereo output. As a result, panning the individual tracks within the stack may not have the desired effect since the final output is in stereo.

To work around this issue, some users suggest removing the tracks from the stack, toggling them to stereo, and then recreating the stack. This approach has been reported to result in a stereo summing stack, allowing the individual tracks' panning settings to take effect. Additionally, it is important to ensure that any plugins used on the stack master are in stereo mode, as mono plugins can interfere with panning.

Another suggestion is to avoid placing the individual tracks you want to pan within the stack. Instead, only use track stacks when you want to apply the same processing to all the tracks within the stack. This way, you can maintain independent control over the panning of each track.

Furthermore, it is worth noting that the specific plugins used on both the individual tracks and the track stack can influence the panning behaviour. Some plugins may affect the panning in unexpected ways, so it is recommended to experiment with different plugins and their settings to achieve the desired panning results.

Reverb bus panning: To achieve reverb bus panning in Logic, you may need to set up the reverb as Dual Mono

Panning a reverb bus in Logic can be achieved by setting up the reverb as Dual Mono. This allows for independent panning of the left and right channels, providing more control over the stereo image.

To do this, follow these steps:

• Set up a reverb bus for your instruments, such as strings, and ensure the send is set to pre-fader so you can adjust the z-depth.
• Pan the individual instruments to their desired positions. For example, you may want a violin on the left and a viola in the middle.
• Open the reverb plugin as Dual Mono. In Logic, this creates two mono instances of the plugin, one for the left channel and one for the right.
• Adjust the settings for each channel independently. For example, you can set the left channel's dry level to max and the reverb to 0, while setting the right channel to a wet guitar sound.
• Listen to the result by soloing the reverb. You should now hear the reverb positioned according to the panning of the individual instruments.

By using Dual Mono, you can achieve a wider and more immersive stereo image for your instruments, with independent control over the reverb positioning for each channel.

Mono vs. stereo: Make sure your bus is set up as a stereo track, as mono EQ on a stereo bus can cause panning issues

When working with audio tracks, it is important to understand the difference between mono and stereo and how this affects panning. Panning is the process of distributing audio signals to different areas in a stereo image, such as left, right, or center.

Mono tracks are single-channel audio signals, while stereo tracks have two channels, left and right, which allows for a wider soundstage and a more immersive listening experience. When panning mono tracks, it is important to ensure that the bus is set up as a stereo track. If a mono EQ is applied to a stereo bus, it can cause issues with panning. The audio signal may be sent with more power to one side, resulting in an unbalanced sound.

To avoid this issue, it is recommended to set up your bus as a stereo track. This will ensure that the left and right channels are treated separately, allowing for accurate panning of individual tracks within the stereo field. By doing so, you can achieve the desired positioning of your audio signals in the stereo image without any unexpected behaviour.

Additionally, it is worth noting that some plugins may affect panning behaviour. It is important to check the settings of your plugins and ensure they are in stereo mode if needed. If you encounter issues with a particular plugin, consider bypassing it or using an alternative.

Furthermore, when working with multiple tracks, it is important to understand the concept of track stacks or buses. A track stack combines multiple tracks into a single group, allowing for easier management and processing. However, panning within a track stack can be tricky, and the behaviour may vary depending on the digital audio workstation (DAW) you are using. In some cases, you may need to toggle individual tracks within the stack to stereo mode to achieve the desired panning effect.

In summary, when working with audio tracks, it is crucial to understand the difference between mono and stereo and how it affects panning. By setting up your bus as a stereo track and ensuring your plugins are in stereo mode, you can achieve accurate panning and maintain the desired stereo image.

Plugins: The plugins you use can affect panning. For example, some third-party plugins may not accept stereo inputs, even if they output stereo

When it comes to panning in Logic, the plugins you use can have an impact. It's important to be aware that certain third-party plugins may not support stereo inputs, even if they are capable of producing stereo outputs. This can result in your panned tracks being summed to mono on the input of the plugin, affecting the overall panning effect.

To address this issue, it's recommended to check the settings of your plugins and ensure they are configured correctly for stereo inputs. Additionally, consider using Logic's built-in Direction Mixer plugin, which offers true stereo panning capabilities. This plugin can be inserted at the beginning of your plugin chain, allowing you to pan your mono track to stereo and then make further adjustments as needed.

Another factor to consider is the type of tracks you are working with. Mono tracks can be panned without any issues. However, with stereo tracks, the pan knob behaves differently. By default, it functions as a balance knob, allowing you to adjust the balance between the left and right sides of a stereo track. To achieve true stereo panning on a stereo track, you need to control-click the pan knob to access the "Stereo Pan" option. This will give you the desired panning effect for both left and right signals.

Additionally, it's worth noting that some users have reported issues with panning when using buses. In some cases, the panning of individual tracks within a bus may not work as expected. This could be due to various factors, including the plugins used, the bus configuration, or other technical considerations. It is always a good idea to check your settings and ensure that your bus is set up correctly for stereo panning.
