The AUv3 standard includes the feature of multiple inputs and outputs per plugin, but it was like a chicken and egg problem: since there were no hosts supporting the feature, there were no plugins that would use it and therefor no need for the hosts to implement it at all. This changed in february 2020.

This page contains a list of hosts and AUs supporting this feature, which is also known as „auv3 multi out“, „multi in“ or „au sidechain“ .
