/* Mixer strip control. Handles GUI and control I/O for this strip. */
/* A mixer strip is home to some (JACK) input ports, a fader, some
* meters, and a filter chain which can terminate either at the input
* to the spacializer or some (JACK) output ports. Since mixer strips
* are not necessarily in a 1:1 association with Non-DAW tracks, there
* is no need for busses per se. If you want to route the output of
* several strips into a single fader or filter chain, then you just
* gives those strips JACK outputs and connect them to the common
* inputs. This mechanism can also do away with the need for 'sends'
* and 'inserts'.
*/
