Harmonic mixing helper section in library.

[Vittorio Colao]

It would be handy if Mixxx could have a library view where all key-compatible songs with the currently playing one are listed.
That will surely help beginners as well as experienced users.

Here is a sketch:

* If a new track is loaded, we should check if it has nonempty "key" tag ( already implemented: Bug #611871 );
* If a "key" tag is found, we query the db for all tracks with compatible keys;
* Results of such query are hence sorted based on how they differ in BPMs from the played one.
* Sorted list is shown in say a "Suggestion Box" library view.

Similar to Bug #872006.

i second this.
i need it very much.
when i play with pioneer hw it helps me by showing key near the track in green colour by signaling that this key is compatible with the key of what is played now so it is one of the choices for the next track.

when you play for hours, and are not able to prepare everything in advance, or if you have to improvise because you read the audience, this is very helpful.

and absence of it is literally a showstopper for using mixxx in many cases.

You can already sort the Mixxx library by key. That's not exactly the same as this feature, but it is very helpful.

thank you.
yes, i have to keep the camelot wheel or something like that nearby for now.

You can change the key notation in the Key Detection section of the preferences if that helps you.
