+	      This opcode does not perform any interpolation.
+        This can lead to unexpected behaviour or unclean signals,
+        e.g. for small table sizes and low frequencies.
+        As standard oscillators the usage of <link linkend="oscili"><citetitle>oscili</citetitle></link>
+        or <link linkend="poscil"><citetitle>poscil</citetitle></link> is recommended.
