2BusControl VST DOWNLOAD FREE CORERELATION METER comprehensive stereo master monitoring & metering plug-in!

2BusControl is available for all major plug-in formats, including VST 2, VST 3, and AAX for macOS and Windows, as well as Audio Units for macOS. It includes five essential monitoring modes, as well as highly responsive and user-friendly metering for left/right balance and correlation. With a single button press, Solo is available for post-metering. Traditional left/right soloing (as phantom centre) or the equally useful MONO/DIFF(erence) or M/S (Mid/Side) rendering of the soloed signal are both options. Mono mode allows you to listen for cancellation in the phantom centre and is also useful for determining how the centre relates to the edge with content panned for separation.

Another requirement for any engineer is usable metering, and the options are equally practical, with stereo balance and inter-channel correlation occupying the upper half of the user interface. Unlike previous products that provide similar metering functions, 2BusControl's measurement and display algorithms adhere to our guiding philosophy of improving ergonomics and workflow by paying close attention to how you actually work. Ballistics are fine-tuned to achieve the best possible match between the aural impression you hear and the optical rendering provided by the metres.

All of 2BusControl's functionality is contained within an information-rich but visually unobtrusive user interface that takes up only a small portion of screen real estate. Similarly, the plug-in is "lightweight," requiring only a small amount of CPU resources and thus not slowing down your computer.


2BusControl delivers indispensable monitoring controls, plus visually expressive metering.
