What steps will reproduce the problem? 1. Change ControlP5Properties sets example to have this: cp5.addSlider("slider2", 0, 255, 20, 100, 128, 20).setId(1).setTriggerEvent(Slider.RELEASE); 2. Add these prints: void b4(float v) { println("(1) slider2: " + slider2); cp5.loadProperties(("default.ser")); println("(2) slider2: " + slider2); }

3. Change slider2 value to something, hit save default.
4. Change slider2 value to something else, hit load default.

What is the expected output? What do you see instead? slider2 variable should have the saved value.

Workaround, set all sliders to trigger mode PRESSED before calling loadProperies():

  for(ControllerInterface c : cp5.getAll())
  {
    if(c instanceof Slider)
    {
      Slider s = (Slider)c;
      s.setTriggerEvent(Slider.PRESSED);
    }
  }
  cp5.loadProperties(presetPath);
  // Now set them back...
