**NOTE**: In firmware 5.4.0, some changes to the default settings should be made in order to get the VP4 working correctly. In Devices, turn on **Send CCs On Preset Change** for the VP4 device. On each IA button that controls a VP4 effect block or channel, turn on **Send on Preset Change** and **Update on Preset Change**.
