    <h2>Built-In Variables</h2>
    <p>
      These are the built-in variables and built-in constants available with the
      NKSP realt-time instrument script language.
    </p>

    <h3>Core Language Variables</h3>
    <p>
      Most fundamental NKSP built-in variables, independent from any purpose of
      being used in a sampler.
    </p>
    <table>
      <tr>
        <th>Variable</th> <th>Description</th>
      </tr>
      <tr>
        <td><code>$KSP_TIMER</code></td>
        <td>Preserved for compatiblity reasons with KSP, returns the same value
           as <code>$NKSP_REAL_TIMER</code> (refer to the latter for details).
           Note that KSP's <code>reset_ksp_timer()</code> function is not available with
           NKSP. However when calculating time differences between two time
           stamps taken with <code>$NKSP_REAL_TIMER</code>, calling such a reset
           function is not required, because the underlying clock does not stop
           when it reached its value limit (which happens every 71 minutes), instead the clock
           will automatically restart from zero and the calculated time difference
           even between such transitions will reflect correct durations.</td>
      </tr>
      <tr>
        <td><code>$NKSP_PERF_TIMER</code></td>
        <td>Returns the current performance time stamp (in microseconds) of the
            script running. You may read this variable from time to time to take
            time stamps which can be used to calculate the time difference
            (in microseconds) which elapsed between them. A performance time
            stamp is based on the script's actual CPU execution time. So the
            internal clock which is used for generating such time stamps is only
            running forward if the respective script is actually executed by the
            CPU. Whenever your script is not really executed by the CPU (i.e. because
            your script got suspended by a wait() call or got forcely suspended due to
            real-time constraints, or when the entire sampler application got suspended
            by the OS for other applications or OS tasks) then the underlying internal
            clock is paused as well.
            <note class="important">
              You should only use this built-in variable for script development
              purposes (i.e. for bench marking the performance of your script).
              You should <b>not</b> use it with your final production sounds!
              It is not appropriate for being used in a musical context, because
              when an offline bounce is performed for instance, the musical timing
              will be completely unrelated to the CPU execution time. Plus using
              this variable may cause audio drop outs on some systems. In a musical
              context you should use <code>$ENGINE_UPTIME</code> instead, which is
              also safe for offline bounces.
            </note>

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

            time stamps which can be used to calculate the time difference
            (in microseconds) which elapsed between them. A "real" time
            stamp is based on an internal clock which constantly proceeds, so this
            internal clock also continues counting while your script is either suspended
            (i.e. because your script got suspended by a wait() call or got forcely
            suspended due to real-time constraints) and it also continues counting
            even if the entire sampler application got suspended by the OS (i.e. to

          This array variable only contains IDs of notes which were launched due
          to MIDI note-on events. This variable does not contain IDs of child notes

            In contrast to KSP this variable is an integer array type, whereas KSP's
            pendent of this built-in variable is an integer constant (scalar) called
            <code>$ALL_EVENTS</code>. Using the latter with NKSP will cause a
