Normally I wanted to share my big Car LED project later, when everything works fine, but now I need your help. My own code works very well, which is object orientated, with an event handler for dealing simutanously with different effects and stripes and you can see in the video one pulse effect of it. But now I wanted to add the Audio Shield from the teensy and there was the Problem with flickering if I play music and with different blue colors if I dont play music. In the files there is also an easy example where I added Fast Led with an effect and the wave player which works very fine, but not in my code and the Question is why??? I use Fastled 3.1 and the newest Arduino IDE and Teensyduino. I programm with Visual Studio and visual micro, but thats not the Problem, if I upload the code with Arduino IDE there is the same Problem. Maybe one of you could help me. @Daniel_Garcia @Mark_Kriegsman … And the others feel free to look into the object orientated code 
Here is the Project:
Maybe its an problem because of performance, or the HSV arrays, which are converted via hsv2rgbrainbow…?
