Problem Beads and Control P5

Hi, this is my first post on this forum os i'm sorry if my question isn't at the right place. I'm using Processing 3.1.1 and I have some problems with Beads. I'm using ControlP5 to change the gain of my Audioplayer but look at this code, it gives me a really long error from the void Musique and I don't know why. paste2.org/eAL307Hd

Then the 2nd problem is when I start a long music, sometimes the program takes tool long to launch and it gives me this errorjava.lang.RuntimeException: Waited 5000ms for: <6c8aac95, 624d5f74>[count 2, qsz 0, owner <main-FPSAWTAnimator#00-Timer0>] - <main-FPSAWTAnimator#00-Timer0-FPSAWTAnimator#00-Timer1> at processing.opengl.PSurfaceJOGL$2.run(PSurfaceJOGL.java:449) at java.lang.Thread.run(Thread.java:745)

And finally I'd like to know how to loop a sound because when i use setToLoopStart() and .KillOnEnd() it tells me that those functions doesn't exist.

Thanks for your help :)
