please help with this midi script

I'm trying to compare incoming notes against an array (well, eventually a bunch of arrays) which is filled by UI sliders, but something goes wrong in the "IF" line.

can someone please help?

var chan = 0;

var PluginParameters = [

{ name:'common note 1', type:'lin',

minValue:36, maxValue:60, numberOfSteps:24, defaultValue:48},

{ name:'common note 2', type:'lin',

minValue:36, maxValue:60, numberOfSteps:24, defaultValue:48},

{ name:'common note 3', type:'lin',

minValue:36, maxValue:60, numberOfSteps:24, defaultValue:48},

{ name:'common note 4', type:'lin',

minValue:36, maxValue:60, numberOfSteps:24, defaultValue:48},

{ name:'group A note 1', type:'lin',

minValue:36, maxValue:60, numberOfSteps:24, defaultValue:48},

{ name:'group A note 2', type:'lin',

minValue:36, maxValue:60, numberOfSteps:24, defaultValue:48},

{ name:'group A note 3', type:'lin',

minValue:36, maxValue:60, numberOfSteps:24, defaultValue:48},

{ name:'group B note 1', type:'lin',

minValue:36, maxValue:60, numberOfSteps:24, defaultValue:48},

{ name:'group B note 2', type:'lin',

minValue:36, maxValue:60, numberOfSteps:24, defaultValue:48},

{ name:'group B note 3', type:'lin',

minValue:36, maxValue:60, numberOfSteps:24, defaultValue:48},

{ name:'group C note 1', type:'lin',

minValue:36, maxValue:60, numberOfSteps:24, defaultValue:48},

{ name:'group C note 2', type:'lin',

minValue:36, maxValue:60, numberOfSteps:24, defaultValue:48},

{ name:'group C note 3', type:'lin',

minValue:36, maxValue:60, numberOfSteps:24, defaultValue:48}

];

var common = ['common note 1', 'common note 2', 'common note 3', 'common note 4'];

var groupA = ['group A note 1', 'group A note 2', 'group A note 3'];

var groupB = ['group B note 1', 'group B note 2', 'group B note 3'];

var groupC = ['group C note 1', 'group C note 2', 'group C note 3'];

function HandleMIDI(event) {

if (event instanceof NoteOn) {

for (i=0; i < common.length; i++) {

if (event.pitch == common) {

event.send();

break;

}

}

}}

papiel,

After a brief look...

A Javascript statement like

var groupA = ['group A note 1', 'group A note 2', 'group A note 3'];

does not get a parameter value and put it in your array groupA. It merely puts the string, not number, value "group A note 1" in your array. You need to do something like use GetParameter('group A note 1') to actually get the parameter value.

Look up GetParameter in the effects manual.

HTH,

thanks!

I figured that's where things go wrong. I'll start by taking the UI element out of the picture and work on the algorithm first then try to incorporate the sliders.

ok so I got the rest of it, but now how do I

1. create a series of UI sliders (preferably with note names - C, C# etc.. over two octaves)

2. get the current sliders positions into an array

3. compare incoming midi notes' pitch with the arrays?

There is a folder called Tutorial Scripts in the presets menu for scripter. You can basically copy/paste a slider from there (I reccomend using something like TextMate or TextWrangler for the actual editing, the built in editor is horrific).

1. Check out the tutorials "Slider Creation" - although if you want note names you will have to make a menu instead so "Menu Creation".

2. Either the function GetParameter("whateverparameter") or ParameterChanged.

If you look at the Sustain Pedal script I made it contains some of this stuff in conext.
