214 <h2>Built-In Variables</h2>
215 <p>
216 These are the built-in variables and built-in constants available with the
217 NKSP realt-time instrument script language.
218 </p>
219
220 <h3>Core Language Variables</h3>
221 <p>
222 Most fundamental NKSP built-in variables, independent from any purpose of
223 being used in a sampler.
224 </p>
225 <table>
226 <tr>
227 <th>Variable</th> <th>Description</th>
228 </tr>
229 <tr>
230 <td><code>$KSP_TIMER</code></td>
231 <td>Preserved for compatiblity reasons with KSP, returns the same value
232 as <code>$NKSP_REAL_TIMER</code> (refer to the latter for details).
233 Note that KSP's <code>reset_ksp_timer()</code> function is not available with
234 NKSP. However when calculating time differences between two time
235 stamps taken with <code>$NKSP_REAL_TIMER</code>, calling such a reset
236 function is not required, because the underlying clock does not stop
237 when it reached its value limit (which happens every 71 minutes), instead the clock
238 will automatically restart from zero and the calculated time difference
239 even between such transitions will reflect correct durations.</td>
240 </tr>
241 <tr>
242 <td><code>$NKSP_PERF_TIMER</code></td>
243 <td>Returns the current performance time stamp (in microseconds) of the
244 script running. You may read this variable from time to time to take
245 time stamps which can be used to calculate the time difference
246 (in microseconds) which elapsed between them. A performance time
247 stamp is based on the script's actual CPU execution time. So the
248 internal clock which is used for generating such time stamps is only
249 running forward if the respective script is actually executed by the
250 CPU. Whenever your script is not really executed by the CPU (i.e. because
251 your script got suspended by a wait() call or got forcely suspended due to
252 real-time constraints, or when the entire sampler application got suspended
253 by the OS for other applications or OS tasks) then the underlying internal
254 clock is paused as well.
255 <note class="important">
256 You should only use this built-in variable for script development
257 purposes (i.e. for bench marking the performance of your script).
258 You should <b>not</b> use it with your final production sounds!
259 It is not appropriate for being used in a musical context, because
260 when an offline bounce is performed for instance, the musical timing
261 will be completely unrelated to the CPU execution time. Plus using
262 this variable may cause audio drop outs on some systems. In a musical
263 context you should use <code>$ENGINE_UPTIME</code> instead, which is
264 also safe for offline bounces.
265 </note>
266 <note>
267 On some systems <code>$NKSP_REAL_TIMER</code> and
268 <code>$NKSP_PERF_TIMER</code> will actually return the same value. So the
269 difference between them is not implemented for all systems at the moment.
270 </note>
271 </td>
272 </tr>
273 <tr>
274 <td><code>$NKSP_REAL_TIMER</code></td>
275 <td>Returns the current time stamp in reality (in microseconds). You may
276 read this variable from time to time to take
277 time stamps which can be used to calculate the time difference
278 (in microseconds) which elapsed between them. A "real" time
279 stamp is based on an internal clock which constantly proceeds, so this
280 internal clock also continues counting while your script is either suspended
281 (i.e. because your script got suspended by a wait() call or got forcely
282 suspended due to real-time constraints) and it also continues counting
283 even if the entire sampler application got suspended by the OS (i.e. to
284 execute other applications for multi-tasking or to perform OS tasks).
285 <note class="important">
286 You should only use this built-in variable for script development
287 purposes (i.e. for bench marking the performance of your script).
288 You should <b>not</b> use it with your final production sounds!

290 when an offline bounce is performed for instance, the musical timing
291 will be completely unrelated to the CPU execution time. Plus using
292 this variable may cause audio drop outs on some systems. In a musical
293 context you should use <code>$ENGINE_UPTIME</code> instead, which is
294 also safe for offline bounces.

297 On some systems <code>$NKSP_REAL_TIMER</code> and
298 <code>$NKSP_PERF_TIMER</code> will actually return the same value. So the

358 This array variable only contains IDs of notes which were launched due
359 to MIDI note-on events. This variable does not contain IDs of child notes
360 (i.e. notes which were launched programmatically by calling <code>play_note()</code>).
361 <note>
362 In contrast to KSP this variable is an integer array type, whereas KSP's
363 pendent of this built-in variable is an integer constant (scalar) called
364 <code>$ALL_EVENTS</code>. Using the latter with NKSP will cause a
365 parser warning, the behavior will be the same though.

452 based on the internal sample rate and thus it can safely be used to
453 perform musical timing related tasks in your scripts. Especially
454 your script will also continue to behave correctly when an offline bounce
