With Loopback you can create custom routing configurations using both applications and device inputs and then use those within appications or send to multiple output devices. This is useful if you want to combine audio from your mic & other audio sources like Kyma. It is also useful for capturing audio into a sound editor, kyma, or a daw that comes from another application (like a web broswer).
