Minim core | ugens | analysis |
FilePlayer loop | Description Sets looping to continuous. If this is already playing, the position will not be reset to the beginning. If this is not playing, it will start playing. Signature
    void loop()
    void loop(int loopCount)
Parameters loopCount — int: the number of times to loop Returns None Related loopCount ( ) setLoopPoints ( ) isLooping ( ) FilePlayer Example
    /**
      This is an example of how to use a FilePlayer UGen to play an audio file. It support all of the same formats that
      AudioPlayer does, but allows you to insert the audio from the file into a UGen chain. FilePlayer provides all the
      same methods that AudioPlayer does for controlling the file playback: play(), loop(), cue(int position), etc.
      <p>
      Press any key to pause and unpause playback!
