2BusControl — Free Essential Monitor Control & Metering

Get your no cost, comprehensive stereo master monitoring & metering plug-in!


2BusControl :: Cross–platform Plug–in

A universal L/R plus MONO/DIFF monitor control and Balance/Correlation metering plug-in for stereo bus masters.


Available for all major plug-in formats, including VST 2, VST 3 and AAX for macOS and Windows plus Audio Units for macOS, 2BusControl offers five essential options for specialized monitoring modes plus highly responsive and user-friendly metering for left/right balance and correlation. Solo is available post-metering with a single button push. Traditional left/right soloing (as phantom center) can be chosen, or the equally useful MONO/DIFF(erence) or M/S (Mid/Side) rendering of the soloed signal. Mono mode lets you listen for any cancellation in the phantom center, and is also important for checking how the center relates to the edge with content panned for separation.
In addition, the stereo perspective can be swapped or flipped with the left and right channels changing places. Each solo control is a single button, allowing you to check placement and amplitude easily for all aspects of your mix.

Usable metering is another essential for any engineer, and options are equally practical, with stereo balance and inter-channel correlation occupying the upper half of the user interface. Unlike prior products that provide similar metering functions, 2BusControl´s measurement and display algorithms adhere to our guiding philosophy of enhancing your workflow and improving ergonomics through careful attention to the way you actually work. Ballistics are meticulously tuned to achieve the best match between the aural impression you hear and the optical rendering by the meters.

All of 2BusControl´s functionality is wrapped in an information-rich yet visually unobtrusive user interface that occupies only a small slice of screen real estate. Likewise, the plug-in is “light weight,” demanding a minimum of CPU resources so it won´t slow down your host. As an introduction to everyone in the audio community, “Hi everybody!”, we’re giving you this free and rather useful plug-in. Please tell your friends and colleagues…Thanks for visiting, and we hope to be working with you more in the future!
