      <emphasis>xfreq1, xfreq2</emphasis> -- the frequency (i.e. the inverse of delay time) Changed to x-rate in Csound version 3.59.

    <para>
      <emphasis>kcutoff1, kcutoff2</emphasis> -- the filter cutoff frequency in Hz.

      <emphasis>kfeedback1, kfeedback2</emphasis> -- the feedback factor
    </para>

    <para>
      <emphasis>wguide2</emphasis> is a model of beaten plate consisting of two parallel delay-lines and two first-order lowpass filters. The two feedback lines are mixed and sent to the delay again each cycle.
    </para>

    <para>
      Implementing waveguide algorithms as opcodes, instead of orc instruments, allows the  user to set <emphasis>kr</emphasis> different than <emphasis>sr</emphasis>, allowing better performance particulary when using real-time.
