An UI element or midi controller will update the associated value immediately after a value change. This may cause a lot of packets to be sent to the mixer which may cause stuttering of the movement on a bad connection / with a lot of clients.
The outgoing packets should be rate limited. For this to be the most efficient the UI should only update the associated value every X ms (where X >= 30, needs to be tested). The internal clock for this process needs to be defined
