NKSP. However when calculating time differences between two time |

stamps taken with <code>$NKSP_REAL_TIMER</code>, calling such a reset |

function is not required, because the underlying clock does not stop |
173 |

time stamps which can be used to calculate the time difference |
182 |
|
(in microseconds) which elapsed between them. A performance time |
183 |
|
stamp is based on the script's actual CPU execution time. So the |
184 |
|
internal clock which is used for generating such time stamps is only |
185 |
|
running forward if the respective script is actually executed by the |
186 |
|
CPU. Whenever your script is not really executed by the CPU (i.e. because |
187 |
|
your script got suspended by a wait() call or got forcely suspended due to |
188 |
|
real-time constraints, or when the entire sampler application got suspended |

when an offline bounce is performed for instance, the musical timing |

this variable may cause audio drop outs on some systems. In a musical |
