// Based on Numark Mixtrack Mapping Script Functions
// 1/11/2010 - v0.1 - Matteo <matteo@magm3.com>
//
// 5/18/2011 - Changed by James Ralston
//
// Known Bugs:
//	Mixxx complains about an undefined variable on 1st load of the mapping (ignore it, then restart Mixxx)
//	Each slide/knob needs to be moved on Mixxx startup to match levels with the Mixxx UI
//
// 05/26/2012 to 06/27/2012 - Changed by Darío José Freije <dario2004@gmail.com>
//
//	Almost all work like expected. Resume and Particularities:
//
// ************* Script now is Only for 1.11.0 and above *************
//
//	Delete + Effect: Brake Effect (maintain pressed).
//			 Flanger Delay (2nd knob of effect section): Adjust the speed of Brake.
//
//	Delete + Hotcues: Clear Hotcues (First press Delete, then Hotcue).
//	Delete + Reloop:  Clear Loop.
//	Delete + Manual:  Set Quantize ON (for best manual loop) or OFF.
//	Delete + Sync: 	  Set Pitch to Zero.
//
// 	Load track: 	Only if the track is paused. Put the pitch in 0 at load.
//
//  	Gain: 	The 3rd knob of the "effect" section is "Gain" (up to clip).
//
//	Effect:	Flanger. 1st and 2nd knob modify Depth and Delay.
//
//	Cue: 	Don't set Cue accidentally at the end of the song (return to the latest cue).
//		LED ON when stopped. LED OFF when playing.
//		LED Blink at Beat time in the ultimates 30 seconds of song.
//
// 	Stutter: Adjust BeatGrid in the correct place (useful to sync well).
//		 LED Blink at each Beat of the grid.
//
//	Sync:	If the other deck is stopped, only sync tempo (not fase).
//		LED Blink at Clip Gain (Peak indicator).
//
// 	Pitch: 	Up, Up; Down, Down. Pitch slide are inverted, to match with the screen (otherwise is very confusing).
//		Soft-takeover to prevent sudden wide parameter changes when the on-screen control diverges from a hardware control.
//		The control will have no effect until the position is close to that of the software,
//		at which point it will take over and operate as usual.
//
// 	Auto Loop (LED ON): 	Active at program Start.
//				"1 Bar" button: Active an Instant 4 beat Loop. Press again to exit loop.
//
//	Scratch:
//	In Stop mode, with Scratch OFF or ON: 	Scratch at touch, and Stop moving when the wheel stop moving.
//	In Play mode, with Scratch OFF: 	Only Pitch bend.
// 	In Play mode, with Scratch ON: 		Scratch at touch and, in Backwards Stop Scratch when the wheel stop moving for 20ms -> BACKSPIN EFFECT!!!!.
//						In Fordward Stop Scratch when the touch is released > Play Immediately (without breaks for well mix).
//						Border of the wheels: Pitch Bend.
