Manage your midrange priority with surgical precision.
Finding the right balance between dense mid-range instruments—like pads, synths, and pianos—and your lead vocal is a constant mix challenge. 
 
Standard broadband sidechaining acts as a blunt tool, ducking the entire volume of your instrument bus uniformly.
This custom Ableton Audio Effect Rack offers a smarter approach. It analyzes the spatial profile of your vocal track and manages the attenuation of your instruments' mid frequencies in real-time, applying the process exactly where the conflict occurs dynamically. 
 
Not only for vocals
Also highly effective for other use cases, such as prioritizing a Main Lead over backing synths.
 
One-Macro Depth Control: Drop the rack onto your instrument bus, select your vocal track as the sidechain input inside the device, and use the main macro knob to dial in the exact level of priority your arrangement needs.
 
Advanced Controls Mode: Total Command Under the Hood
Need deeper customization? If you want to move beyond the one-knob workflow, just click a button to expand the device. The rack opens up into an Advanced Controls Mode, giving you total manual command over the internal dynamic EQ matrix.
 
Intelligent Mid/Side Automation
The rack handles all Mid/Side processing automatically, dynamically adapting to your vocal track with zero manual adjustment:
Reactive Spatial Automation: Automatically tracks the vocal image. Mono vocals duck only the center (Mid) channel, while stereo/wide layers instantly scale the ducking to the sides (Sides).
Built-in Transient Management: Calculates center and side dynamics independently, preventing awkward pumping artifacts and keeping the stereo width stable.
Fixed Crossover Precision: Operates within a pre-calibrated frequency zone where vocals and instruments typically clash. The dynamic EQ ducks the volume exactly in this pocket, clearing space without changing the crossover points.
 
No more masking! Just drop it in, select your vocal track, and give your vocals the exact space they need to cut cleanly through the mix.
