Audio Class Configuration Audio Class configurations are default configurations provided by SKAARHOJ that work with controllers that have at least 4 Faders as their main components. To use them in Reactor, select a "Generic Audio" configuration for your panel, then fill the channel config with devices. See Audio Class Config to learn how to configure it. All Audio Class compatible controllers are: Wave Board (V2) Wave Board Mini Color Fly (V2, V3) Wave Board (V1) Wave Board V1 has an alternative setup utilizing the extra two buttons instead of the encoder.
