      STK Fender Rhodes-like electric piano FM synthesis instrument.</para>
    <para>
      This opcode implements an instrument based on two simple FM Pairs
      summed together, also referred to as algorithm 5 of the Yamaha TX81Z.
      It simulates the sound of a Rhodes electric piano, and some related sounds.

      <para>
         The code for this opcode is taken directly from the Rhodey class in the Synthesis Toolkit in C++ by Perry R. Cook and Gary P. Scavone. More on the STK classes can be found here:  
<ulink url="https://ccrma.stanford.edu/software/stk/classes.html"><citetitle>https://ccrma.stanford.edu/software/stk/classes.html</citetitle></ulink>

        <emphasis>kc1, kv1, kc2, kv2, kc3, kv3, kc4, kv4, kc5, kv5, kc6, kv6, kc7, kv7, kc8, kv8</emphasis> -- Up to 8 optional k-rate controller pairs for the STK opcodes.
      Each controller pair consists of a controller number (kc) followed by a controller value (kv). Both the controller numbers and the controller values are krate variables. However, during a performance, normally the controller numbers stay fixed while the corresponding controller values may change at any time.
The order of the controller pair is arbitrary, as long as they are after <emphasis>iamplitude</emphasis>. Also, it is not needed that all controller pairs are used.
