<para>

</para>
<para>
<emphasis>lineto</emphasis> adds glissando (i.e. straight lines) to a stepped input signal (for example, produced by <link linkend="randh"><citetitle>randh</citetitle></link> or <link linkend="lpshold"><citetitle>lpshold</citetitle></link>). It generates a straight line starting from previous step value, reaching the new step value in <emphasis>ktime</emphasis> seconds. When the new step value is reached, such value is held until a new step occurs. Be sure that <emphasis>ktime</emphasis> argument value is smaller than the time elapsed between two consecutive steps of the original signal, otherwise discontinuities will occur in output signal.
</para>
<para>
When used together with the output of <link linkend="lpshold"><citetitle>lpshold</citetitle></link> it emulates the glissando effect of old analog sequencers.
</para>
<note><para>No new value for <emphasis>ksig</emphasis> or <emphasis>ktime</emphasis> will have effect until the previous <emphasis>ktime</emphasis> has elapsed.</para></note>
