They are actually meant to be *replacements* for the current opcodes,
which are, to put it diplomatically, problematic. If we had wanted to
provide 'state of the art' opcodes or any new functionality they would
have looked rather different.

The decoders should be functionally compatible with the existing ones.

The only thing we did leave out are the per-order gain factors for the
encoding opcode, as this is definitely not the right place to apply
them. I you need a non-standard encoding (but we can't imagine why
you would) it is trivial to apply such gain factors in the orchestra
definition.

If you really want to keep the old ones, at least put a note in their
docs that they have been replaced by a more correct implementation.
