MB-7 Mixer


The multiband mixing console and VST/AU host with built-in effects

Blue Cat's MB-7 Mixer is a unique plugin that splits the signal into several frequency bands and lets you mix and process them as if they were separate tracks. Each band proposes controls that can be found on a mixing console, and more—bypass, mute or solo each band separately to isolate frequencies you want to work on, adjust the gain, the "stereoness" and the position in the stereo field. When manipulating the stereo image, a master mono switch also lets you check mono compatibility.

Apply different audio effects to each band to achieve any kind of spectral manipulation—the plugin can operate as a multiband plugins host. Process each band independently with your favorite VST, VST3 or Audio Unit plugins or choose from any of the 28 built-in effects! Up to four plugins can be loaded on each band, pre or post fader. It also includes 25 built-in audio effects that can be inserted in each plugin slot. Latency compensation, presets management, undo/redo integration, and individual plugin bypass are included for optimal operation.

The plugin also offers unique linking and grouping options thanks to Blue Cat’s multi-instances technology. Link bands together within a single instance or between several instances of the plugin on different tracks. This lets a simple fader control as many bands on as many tracks as you want. This is particularly useful when adjusting the placement or the balance of several competing tracks.

And as usual with Blue Cat Audio, the plugin provides comprehensive visual feedback to let you know exactly what's going on for each channel—monitor the spectrum, the in/out levels and the frequency response.
