How do use my GUI G4P slider to increase the tempo and volume of my audio file?

My sliders are as follows:

public void slider1_change1(GSlider source, GEvent event) { //_CODE_:slider1:634065:
//  println("slider1 - GSlider >> GEvent." + event + " @ " + millis());
tempo = slider1.getValueF();
} //_CODE_:slider1:634065:

public void slider2_change1(GSlider source, GEvent event) { //_CODE_:slider2:997515:
//  println("slider2 - GSlider >> GEvent." + event + " @ " + millis());
  gain = slider2.getValueF();
} //_CODE_:slider2:997515:

Here is my button that plays my audio file in repeat:

public void imgButton1_click1(GImageButton source, GEvent event) { //_CODE_:imgButton1:842456:
  println("imgButton1 - GImageButton >> GEvent." + event + " @ " + millis());
  if (myplayer.isPlaying()) {
  myplayer.pause();
  }
  else  {
  myplayer.loop();
  }
} //_CODE_:imgButton1:842456:

When I click the play/pause button my audio file plays out loud, but I want it to be silent and when I increase the gain the volume increases, along with this the beat plays every second but I want it to increase speed with the slider, help would be greatly appreciated!

My slider values are:

  slider1 = new GSlider(this, 736, 342, 60, 30, 10.0);
  slider1.setRotation(PI/2, GControlMode.CORNER);
  slider1.setLimits(1.0, 1.0, 0.0);
  slider1.setNumberFormat(G4P.DECIMAL, 2);

  slider2 = new GSlider(this, 688, 341, 60, 30, 10.0);
  slider2.setRotation(PI/2, GControlMode.CORNER);
  slider2.setLimits(1.0, 1.0, 0.0);
  slider2.setNumberFormat(G4P.DECIMAL, 2);

Related to the speed, this post provides some insight: https://forum.processing.org/two/discussion/21842/is-it-possible-to-perform-fft-with-fileplayer-object-minim/p1

For volume, you need to work with setGain. I am not sure if there is a mute function in minim. I believe there is mute/unmute in SoundFile library. however I believe minim is your best option. After you figure the volume in minim, then you can create your own mute function when you set the gain to zero.

Before integrating your music component to the GUI, I suggest you explore the examples provided by minim (File>>examples and then Additional Libraries) or explore previous post: https://forum.processing.org/two/search?Search=setgain
