Arturia Minilab Mk2 Bitwig Controller Script

// Extended version from Nettsu v1.0 - https://github.com/Nettsu/minilab-mkII-bitwig
// by nojoe v1.2, at the moment the controller settings are my test defaults!
// .. Pad 1&2 scroll now between tracks; Pad 5 Overdub toggle; Knob 9 hold for Metronome
//
//
// ToDo:
//
// 1. [Shift + Pad 1/2] scroll between devices ( deviceCursor.selectPrevious & deviceCursor.selectNext )
// 2. Knob1click - Resets macro values. Possible to resets to macro preset defaults then to 0?
// 3. Knob9click - Metronome on/off. Needs a fix: At the moment holding the Knob activates the Click,
//    release the Knob deactivates the Click!
// 4. Knob7 - Song pointer position
//    In Controller Setting: Independent Knob speed for adjusting to fit personal preference
// 5. Knob8 - Panning of the selected track
// 5. Knob15 - Global data up/down like arrow up/down on keyboard?
//    In Controller Setting: Independent Knob speed for adjusting to fit personal preference
// 6. Knob16 - Volume of the selected track
// 7. Pad 9-16 - Delete Note/Control toggle in controller setting and use Pad buttons to switch between Control and Note playing!
