The Mixer class acts in a similar way to a studio mixing desk - it represents the values of all the knobs and sliders you might find (in the MIDI realm). The values it stores include main volume, channel volume, channel pan, channel reverb, etc.
The values can be updated in real time according to MIDI input, MIDI output, or both. Values can be altered and sent back out through MIDI out.
It contains a number of MixerPort objects which hold the state for each MIDI port in the system.
