Depending on the software, it could even be higher quality when bouncing to
disk directly. However this is only the case if you are using control signals
that have to be sample accurate and your software would otherwise render them
based on audio blocks. This is what some people use CSound and SuperCollider
in NRT mode for. In that case, it may take longer than a realtime bounce
though.

In regular DAW software, I could also imagine that on certain parts where
there is a lot of DSP going on (lot of effects for example), directly
bouncing to disk may also be better, as the calculation does not *have* to be
realtime, so where maybe in realtime you'd get hickups, rendering to disk may
be safer.

It could be that some ProTools stuff needs to drag it through their hardware
DSP's that will only run in realtime mode. In that case I could imagine there
is a quality difference between letting the host PC do it, or the ProTools
hardware DSP's. And this is probably where the myth comes from.
