Although <span class="emphasis"><em>kinitndx</em></span> is listed as k-rate, it is in fact accessed only at init-time. So if you are using a k-rate argument, it must be assigned with <a class="link" href="init.html" title="init"><em class="citetitle">init</em></a>.

<p>
<span class="emphasis"><em>kfn_times</em></span> -- number of table containing a sequence of times
</p>
<p>
This opcode handles timed-sequences of groups of values stored into a table.
</p>
<p>
<span class="emphasis"><em>seqtime2</em></span> generates a trigger signal (a
sequence of impulses, see also <a class="link" href="trigger.html" title="trigger"><em class="citetitle">trigger</em></a> opcode),
according to the values stored in the
<span class="emphasis"><em>kfn_times</em></span> table. This table should contain a
series of delta-times (i.e. times beetween to adjacent
events). The time units stored into table are expressed in
seconds, but can be rescaled by means of <span class="emphasis"><em>ktime_unit</em></span> argument. The
table can be filled with <a class="link" href="GEN02.html" title="GEN02"><em class="citetitle">GEN02</em></a> or by means of
an external text-file containing numbers, with <a class="link" href="GEN23.html" title="GEN23"><em class="citetitle">GEN23</em></a>.
</p>
<p>
It is possible to start the sequence from a value different than
the first, by assigning to <span class="emphasis"><em>initndx</em></span> an index
different than zero (which corresponds to the first value of the
table). Normally the sequence is looped, and the start and end of
loop can be adjusted by modifying <span class="emphasis"><em>kstart</em></span> and
<span class="emphasis"><em>kloop</em></span> arguments. User must be sure that
values of these arguments (as well as
<span class="emphasis"><em>initndx</em></span>) correspond to valid table numbers,
otherwise Csound will crash (because no range-checking is
implementeted).
</p>
<p>
It is possible to disable loop (one-shot mode) by assigning the
same value both to <span class="emphasis"><em>kstart</em></span> and
<span class="emphasis"><em>kloop</em></span> arguments. In this case, the last read
element will be the one corresponding to the value of such
arguments. Table can be read backward by assigning a negative
<span class="emphasis"><em>kloop</em></span> value. It is possible to trigger two
events almost at the same time (actually separated by a k-cycle)
by giving a zero value to the corresponding delta-time. First
element contained in the table should be zero, if the user intends
to send a trigger impulse, it should come immediately after the
orchestra instrument containing <span class="emphasis"><em>seqtime2</em></span>
opcode.
</p>
<p>
<span class="emphasis"><em>seqtime2</em></span> is similar to
<a class="link" href="seqtime.html" title="seqtime"><em class="citetitle">seqtime</em></a>,
the difference is that when
<span class="emphasis"><em>ktrig_in</em></span> contains a non-zero value, current index is reset to
<span class="emphasis"><em>kinitndx</em></span> value. <span class="emphasis"><em>kinitndx</em></span> can be varied at performance time.
