The code looks correct, but are defualts are the best user experience here? I guess it would be better to uses the states/values set in Mixxx before: 1.) make connections...

Can we use another term than "Calibration", as many controllers and mixers have calibration feature to compensate the failure of the fader hardware (usually the end and center position values...

I'm thinking about the proposed `stem_X_split` CO. There are so many use cases, and it's difficult, maybe impossible, to cover them with COs. Some considerations about stem split mode and...

Should these COs only work for main decks, or also for preview decks and samplers? The later would be difficult to visualize in the UI. But I could imagine the...

Please use snake case for new COs, `LoadSelectedTrack` is legacy naming. Is the extra CO `[ChannelX],stem_Y_split_into_Z` really needed? The value of `[ChannelX],stem_Y_split` is currently unused, why not define it as...

Besides the new COs, it is also important to consider which of the existing COs will behave differently with stem files, e.g.: `[SamplerN]LoadTrackFromDeck` Should it reject the operation or load...
