1. PulseOsc m => SinOsc c =>  dac ;

   220 => c.freq;

   20 => m.freq;

   300 => m.gain;

   float velocity, direction;

   while ( true ) {

           velocity => m.freq;

           direction => c.freq;

           chout <= velocity <= " " <= direction <= IO.newline();

       }

   }

But I don't know how to create a Pulse Oscillator, I'm using minim, have you any idea?

Thanks :)
