<title>Description</title>
<para>
Access values of the current buffer of an a-rate variable by indexing.
Useful for doing sample-by-sample manipulation at k-rate without using
setksmps 1.
<note>
<title>Note</title>
<para>Because this opcode does not do any bounds checking, the user
must be careful not to try to read values past ksmps (the
size of a buffer for an a-rate variable) by using index values greater
than ksmps.</para>
