Ferret 4x4 has been designed to add more audio routing capabilities to BloXpander by taking advantage of its sidechaining and multi-output capabilities. However, it can be used in some other DAWs to create audio links between different channels/tracks.
Ferret 4x4 features four pairs of inputs and four pairs of outputs, each of them having its own adjustable level and pan parameters. The internal behavior of Ferret 4x4 is quite basic: inputs are mixed down and the resulting stereo signal is sent to outputs depending on user settings.
This plug-in can be used to create extra "aux return" channels, mix down multiple signals to be sent to a single effect or a physical output, create headphone mixes, etc.
Please note that how easy (or even possible) it is to use Ferret4x4 highly depends on the host's audio routing capabilities.
