Blue Cat Audio has announced a significant update of Blue Cat’s MB-7 Mixer for the 10th anniversary of this multi-band multi-effect processor, which is also capable of transforming any 3rd party plugin into a multi-band effect.

With a focus on performance and stability, this new version adds a new multicore processing engine that can process each band on a separate CPU core, with up to 7 times the processing power, to load more effects.

Many aspects of the DSP have also been optimized to reduce the CPU and memory usage, and more 3rd party plugins can now be loaded thanks to several compatibility improvements. With many additional features and fixes, this 27th release is a major step forward for this plugin that was initially released in 2011.

An optimized build for the new Apple M1 Macs is also available to customers as a preview, with great performance improvements, as shown in the company’s benchmark comparing Apple M1 and Intel Macs for audio.

  • Reduced time to load the MB-7 Mixer or any built-in plug-in.
  • Multiple DSP performance improvements.
