{{#mpdftags: pagebreak}} The content of the folder will be the following:

1. js_demo_2.5.mxw. This is the demo file, all the JavaScript and the commands we are going to use are saved here.

2. README_JavaScript_demo.txt. Step by step explanation of how to launch and use the JavaScript demo. (You won´t probably need it if you are reading this document).

3. Reference_JavaScript_2.5.pdf . A handbook to understand the usage of JavaScripts in MXWendler. There are many examples that can be pasted and tried in the software in order to understand how to take advantage of JavaScript in your video-workflow.

4. WalkingMan_Outline_Loop_.avi. A sample clip to demonstrate the effect of the scripts.

Scripts content

1. "Backspace"

Key: back

Receiver: /mxw/set/play

Backspace starts a patch in which the clip´s scale is associated with the software´s BPM. The Javascript prints a comment on the console. {{#mpdftags: pagebreak}}

def quickSort(arr):
	less = []
	pivotList = []
	more = []
	if len(arr) <= 1:
		return arr
	else:
		pass

2. "Space Bar"

Key: space bar

Receiver: /mxw/beatbutton

Type: pass value

function on_trigger( triggervalue ) {

	if(triggervalue==1)

{ print_console( "PATCH ACTIVATED. HIT SPACE BAR FOR TAP TEMPO or 1-2-3 TO SET THE OPACITY LEVEL \n" );

} }
