Comment 18 for bug 1531876

For the MIDI dump, perhaps you could annotate it with what's going on like:

1) Move Ch1 volume knob (sync'd, Mixxx is responding)
2) deck switch
3) Move ch3 volume knob (getting CH1 out of sync)
4) deck switch
5) Move ch1 volume knob -- not ignored by soft takeover when it should have been
6) ch1 volume knob approaches on-screen ch1 volume knob position -- not re-sync'd by soft takeover as it should have been
