12 This document gives you an overview of all built-in functions and built-in
13 variables provided by the NKSP real-time instrument script language.

390 <h3>Core Language Variables</h3>
391 <p>
392 Most fundamental NKSP built-in variables, independent from any purpose of
393 being used in a sampler.

395 <table>

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

482 stamp is based on an internal clock which constantly proceeds, so this
483 internal clock also continues counting while your script is either suspended
484 (i.e. because your script got suspended by a wait() call or got forcely
485 suspended due to real-time constraints) and it also continues counting
486 even if the entire sampler application got suspended by the OS (i.e. to
487 execute other applications for multi-tasking or to perform OS tasks).

568 This may be passed to many built-in functions like <code>note_off()</code>.

570 to MIDI note-on events. This variable does not contain IDs of child notes
571 (i.e. notes which were launched programmatically by calling <code>play_note()</code>).
572 <note>
573 In contrast to KSP this variable is an integer array type, whereas KSP's
574 pendent of this built-in variable is an integer constant (scalar) called
575 <code>$ALL_EVENTS</code>. Using the latter with NKSP will cause a
