[chuck-users] using global variables as arguments in sporking functions

[Julien Saint-Martin]

Hi Herman,

I think you must use your CFreq (global variable) inside your second
function. And update the parameter you want inside the loop :

fun void LFO(float LFOfreq) {
    SinOsc lfo => blackhole;
    LFOfreq => lfo.freq;
    while( true )
    {
    1::samp => now;
    lfo.last() => c.gain ;

    *CFreq => lfo.freq;*

    }
}

Have fun,

Julien
