Cantabile now supports a new MIDI filter that supports decoding HUI switch messages.
The HUI spec encodes button presses using two CC messages and uses a concept of zones and ports. A zone typically represents a group of buttons such as a channel strip while a port represents a particular button in that zone. Each zone has 8 ports and there are about 30 defined zones.
