Hello there

I am doing  “classes” and “objects” and i ‘ve the next problem

in the code : 


// Simple example of sound making class
 class Simple
{
    //sound chain
   Impulse imp => ResonZ filt => dac;
    
    // some default settings
    100.0 => filt.Q => filt.gain;
    1000.0 => filt.freq;
    
    fun void freq(float f)
    {
        f => filt.freq;
        
    }
    
    fun void setQ(float Q)
    {
        
        Q => filt.Q => filt.gain;
        
    }
    
    fun void setGain(float g)
    
    {
        g => imp.gain;
        
    }
    
    fun void noteOn (float volume)
    {
        volume => imp.next;
    }
    
    
}

Simple s;

while(true)
{
    
    
    Math.random2f(1100.0, 1200.0) => s.freq;
    Math.random2(1,200) => s.setQ;
    Math.random2f(.2,.8) => s.setGain;
    // play note 
    1 => s.noteOn;
    .1::second => now;
} 





My console monitor return:

[Untitled]:line(3): ugen's of type 'DAC' have no input - cannot => from another ugen...
[simple_class]:line(5): ugen's of type 'DAC' have no input - cannot => from another ugen...




Someone knows what is happening
Thank you
