MIX WINDOW CONTROLS
SEND selectors
In Pro Tools, the use of "sends" in the Mix Window is fundamental for flexible and efficient mixing processes. Sends allow audio signals from one track to be routed to another track, typically an auxiliary input track, where you can apply effects like reverb, delay, or compression that you want to share across multiple tracks. This approach has several key benefits in a mixing environment:
1. **Resource Efficiency**: By using sends, you can apply a single instance of an effect on an auxiliary track and share it across multiple tracks. This is much more CPU-efficient than inserting the same effect individually on each track. It helps manage system resources better, especially in large sessions with many tracks.
2. **Consistency of Effects**: Sends help maintain consistency in the effects applied across different tracks. For example, using the same reverb send for multiple vocal tracks can help blend them into the same sonic space, creating a more cohesive mix.
3. **Control and Flexibility**: Sends allow precise control over the amount of signal sent from the original track to the auxiliary track. This means you can easily adjust how much of an effect is applied to different elements of the mix without changing the settings of the effect itself—just the send levels.
4. **Automation**: You can automate the send levels just as you would with other parameters in Pro Tools. This capability allows for dynamic changes in the effects throughout a track, such as increasing reverb at certain points for dramatic effect or pulling back on delay in more dense sections of a mix.
5. **Complex Routing Capabilities**: Sends can be used for more than just effects. They can route audio to submixes, headphone mixes, and more. This is particularly useful in recording sessions where different performers may need custom headphone mixes.
6. **Non-Destructive**: Since sends are a routing tool, they don’t alter the original dry signal. You retain the original track untouched, which gives you a lot of flexibility in balancing the dry and wet signals, and if needed, you can completely remove the effects without affecting the original audio.
Overall, the use of sends in the Mix Window in Pro Tools provides significant advantages in terms of mixing efficiency, consistency, and creative control, making them indispensable tools in the audio production workflow.

In the context of audio processing and mixing, the terms "dry" and "wet" refer to the amount of signal processing, particularly with effects, that has been applied to an audio signal:
1. **Dry**: This term refers to the original, unprocessed audio signal. A dry track has no added effects such as reverb, delay, chorus, or any other form of processing that alters the original sound. The dry signal is essentially the clean, unmodified sound as it was recorded or produced.
2. **Wet**: Contrary to dry, a wet signal refers to the audio after it has had effects applied. The more effects added, the "wetter" the sound becomes. A fully wet signal would be one where only the processed effects are audible, with none of the original dry signal present. This might occur, for example, if you are using a reverb effect and set the mix parameter to 100% wet, thereby excluding all of the dry signal.
### How They Are Used:
- **Mixing Dry and Wet Signals**: In many mixing scenarios, a blend of dry and wet signals is used. For instance, you might have a vocal track where you want to add some reverb. You wouldn’t typically make the reverb 100% wet because you would lose the clarity and presence of the original vocal. Instead, you would mix a proportion of the wet (reverb) signal with the dry (original vocal) signal to achieve a balanced sound that fits well in the mix.
- **Send Effects**: This concept is commonly employed in send effects setups, where the dry signal is sent to an auxiliary track via a send. On this auxiliary track, an effect is applied fully wet, and the output of this track is then blended back with the original dry signal. This method provides control over the balance between the processed and unprocessed sounds.
Understanding the balance between dry and wet signals is crucial for effective audio processing, enabling the engineer or producer to maintain

In a typical Pro Tools setup where you use sends for reverb, here's how the routing would generally work:
1. **Original Track (e.g., Vocal Track)**: This is where the original dry signal resides. You will add a send on this track to route part of its signal to an auxiliary track. The amount of signal sent can be adjusted depending on how much reverb you want to mix with the dry signal.
2. **Auxiliary Track**: You create an auxiliary track and insert a reverb plugin on it. This aux track is set up to receive the signal sent from the original track's send. The reverb plugin on this aux track should typically be set to 100% wet because you're only looking to use the processed (reverb) signal from this track, not the original dry signal.
3. **Routing the Auxiliary Track**:
- **To the Master Track**: In most cases, the auxiliary track with the reverb will be routed directly to the master track. This setup allows the reverb to be blended with the overall mix, enhancing the spatial and atmospheric aspects of the sound.
- **To a Subgroup (e.g., Vocal Bus)**: Sometimes, especially in more complex mixes or where you want more detailed control over groups of instruments or vocals, the aux track might be routed to a subgroup or bus (like a vocal master). This subgroup then routes to the master track. This method can be useful if you want to apply additional group processing (like compression or EQ) to the entire vocal group, including the reverb effect, before it hits the master track.
4. **Final Mixdown**: Whether routed directly to the master or through a subgroup, the reverb effect applied on the aux track merges with the rest of the mix. This blending helps achieve a cohesive sound where the reverb enriches the original dry signal without overwhelming it.
### Example Setup in Pro Tools:
- **Track 1 (Vocal Track)**: Contains the dry vocal recording. You add a send on this track, adjusting the send level to determine how much of the vocal signal is fed into the reverb.
- **Aux Track (Reverb Track)**: Receives the signal from the vocal track's send. A reverb plugin is inserted here, set to 100% wet. The output of this aux track is set to route back to the Master Track or a Vocal Bus, depending on your mixing strategy.
This setup allows for efficient use of effects, conserving CPU resources and providing flexibility in the overall mix balance and processing.
