// pitch slider works as you'd expect
// holding down the push button works as a "shift" to activate secondary functions
// needs the cdj101 to be on midi channel 1 for deck1 and 2 for deck2
//
// track playing:
//
// * surface of jog wheel: scratch
// * edge of jog wheel: tempo bend
// * shift + edge of jog wheel: fine tempo bend
//
// track not playing:
//
// * click push button: load a track
// * surface of jog wheel: scratch thru track
// * shift + surface of jog wheel: scan through track quickly
// * edge of jog wheel: jog though track slowly
// * shift + cue: move beatgrid
//
// track playing or not:
//
// * rotate push button: navigate tracks
// * shift + rotate push button: switch between playlists
// * cue button: default cue behaviour
// * play: toggle play
// * shift + play: sync
