Stepped Frequency Selector

[alepan]

Hi all, I'm trying to create a knob to select specific frequencies in steps, something like this:

//TEST
const var Filter1 = Synth.getEffect("Filter1");
const var Low_Freq_Knob = Content.getComponent("Low_Freq_Knob");
const var a = [20, 30, 60, 100];

inline function onLow_Freq_KnobControl(component, value)
{
    for (i = 0; i < 4; i++);
    {
        if (Low_Freq_Knob.getValue() == i)
            Filter1.setAttribute(Filter1.Frequency, a[i]);
    } 
};

Content.getComponent("Low_Freq_Knob").setControlCallback(onLow_Freq_KnobControl);

Unfortunately, it doesn't work; if I use Console.print(Filter1.Frequency), I get four "1" in a row, instead of the four values specified in the "a" array.

The Knob paramters are: min=0, max=3, step=1, mid=1
Any suggestions?
Thanks a lot
