2BusControl is a free stereo master monitoring and metering plug-in designed to enhance your mixing and mastering workflow. Compatible with all major plug-in formats, it offers specialized monitoring modes and precise metering tools that allow you to assess left/right balance and inter-channel correlation with ease. The plug-in’s user interface is compact and visually unobtrusive, ensuring it fits seamlessly into any digital audio workstation setup without demanding excessive screen space or CPU resources.

This plug-in provides intuitive soloing options accessible through simple single-button controls. You can solo left or right channels individually or switch to MONO/DIFF and Mid/Side (M/S) modes to isolate specific elements of your mix. Additionally, 2BusControl allows swapping or flipping the stereo channels to help you verify the spatial placement and amplitude of each part of your audio. These features make it easier to identify and address issues within your stereo field quickly and effectively.

The metering section is engineered for accuracy and usability, with ballistics carefully tuned to match the perceived sound to the visual display perfectly. This ensures that what you hear corresponds closely with what you see on the meters, aiding in precise decision-making during the mastering process. As a lightweight tool optimized for macOS as a Universal Binary 2, 2BusControl maintains high performance without compromising your system’s resources, making it an essential addition to any professional or home studio.
