Encoders are showing up more frequently on controllers. However, they use
the same MIDI events as Continuous Controllers and they have no standard
- way of working. Ardour has implemented 4 of the more common ways of

reversed, use the other. This one is the one the Mackie Control Protocol
uses.

If the wrong one is chosen, either the positive or negative side will act
incorrectly. It is not really possible to auto detect which one the
