as <code>$NKSP_REAL_TIMER</code> (refer to the latter for details). |
| 421 |
Note that KSP's <code>reset_ksp_timer()</code> function is not available with |
| 422 |
NKSP. However when calculating time differences between two time |
| 423 |
stamps taken with <code>$NKSP_REAL_TIMER</code>, calling such a reset |
| 424 |
function is not required, because the underlying clock does not stop |
| 425 |
when it reached its value limit (which happens every 71 minutes), instead the clock |
| 426 |
will automatically restart from zero and the calculated time difference |
| 427 |
even between such transitions will reflect correct durations.</td> |
| 428 |
</tr> |
| 429 |
<tr> |
| 430 |
<td><code>$NKSP_PERF_TIMER</code></td> |
| 431 |
<td>Returns the current performance time stamp (in microseconds) of the |
| 432 |
script running. You may read this variable from time to time to take |
| 433 |
time stamps which can be used to calculate the time difference |
| 434 |
(in microseconds) which elapsed between them. A performance time |
| 435 |
stamp is based on the script's actual CPU execution time. So the |
| 436 |
internal clock which is used for generating such time stamps is only |
| 437 |
running forward if the respective script is actually executed by the |
| 438 |
CPU. Whenever your script is not really executed by the CPU (i.e. because |
| 439 |
your script got suspended by a wait() call or got forcely suspended due to |
| 440 |
real-time constraints, or when the entire sampler application got suspended |
| 441 |
by the OS for other applications or OS tasks) then the underlying internal |
| 442 |
clock is paused as well. |
| 443 |
<note class="important"> |
| 444 |
You should only use this built-in variable for script development |
| 445 |
purposes (i.e. for bench marking the performance of your script). |
| 446 |
You should <b>not</b> use it with your final production sounds! |
| 447 |
It is not appropriate for being used in a musical context, because |
| 448 |
when an offline bounce is performed for instance, the musical timing |
| 449 |
will be completely unrelated to the CPU execution time. Plus using |
| 450 |
this variable may cause audio drop outs on some systems. In a musical |
| 451 |
context you should use <code>$ENGINE_UPTIME</code> instead, which is |
| 452 |
also safe for offline bounces. |
| 453 |
</note> |
| 454 |
<note> |
| 455 |
On some systems <code>$NKSP_REAL_TIMER</code> and |
| 456 |
<code>$NKSP_PERF_TIMER</code> will actually return the same value. So the |
| 457 |
difference between them is not implemented for all systems at the moment. |

internal clock also continues counting while your script is either suspended |
| 486 |
(i.e. because your script got suspended by a wait() call or got forcely |
| 487 |
suspended due to real-time constraints) and it also continues counting |
| 488 |
even if the entire sampler application got suspended by the OS (i.e. to |
| 489 |
execute other applications for multi-tasking or to perform OS tasks). |
| 490 |
<note class="important"> |
| 491 |
You should only use this built-in variable for script development |
| 492 |
purposes (i.e. for bench marking the performance of your script). |
| 493 |
You should <b>not</b> use it with your final production sounds! |
| 494 |
It is not appropriate for being used in a musical context, because |
| 495 |
when an offline bounce is performed for instance, the musical timing |
| 496 |
will be completely unrelated to the CPU execution time. Plus using |
| 497 |
this variable may cause audio drop outs on some systems. In a musical |
| 498 |
context you should use <code>$ENGINE_UPTIME</code> instead, which is |
| 499 |
also safe for offline bounces. |

| 501 |
<note> |
| 502 |
On some systems <code>$NKSP_REAL_TIMER</code> and |
| 503 |
<code>$NKSP_PERF_TIMER</code> will actually return the same value. So the |
| 504 |
difference between them is not implemented for all systems at the moment. |

Note IDs of all currently active notes of the current sampler part (a.k.a. sampler channel). |

This may be passed to many built-in functions like <code>note_off()</code>. |
| 571 |
This array variable only contains IDs of notes which were launched due |
| 572 |
to MIDI note-on events. This variable does not contain IDs of child notes |
| 573 |
(i.e. notes which were launched programmatically by calling <code>play_note()</code>). |

<note> |
| 575 |
In contrast to KSP this variable is an integer array type, whereas KSP's |
| 576 |
pendent of this built-in variable is an integer constant (scalar) called |
| 577 |
<code>$ALL_EVENTS</code>. Using the latter with NKSP will cause a |
| 578 |
parser warning, the behavior will be the same though. |
