This request is a little off-topic for musicians, and relates more to
the SE aspects of Csound.

I am looking for a set of simple tests to ensure that opcodes are
working correctly.  I realise that this is a major undertaking, but at
the very least I would like tests for the opcodes I did not originate,
and especially the filter opcodes (moogvcf, rezzy, biquad, lowpres,
resonx, ...).  I have tests for the physical model opcodes already,
and also some for fog and some others.  I am concerned that I might
(again) upset opcodes when attempting to optimise or entend.

So does anyone have any such test?  I am looking for single opcode
instruments, or conceptually single opcodes, possibly with the correct
output as well.  Ideally I would like to create a set of automated
tests I could run, and they would also act as trivial examples of use
in some cases.
