Sound Code in void draw makes me problem

Processing Libraries

Just declare 2 variables like you would do for any other kind of variables:

import processing.sound.*;

SoundFile soundfile1;
SoundFile soundfile2;

void setup() {
  ...
  soundfile1 = new SoundFile(this, "file1.aiff");
  soundfile2 = new SoundFile(this, "file2.aiff");
}
