Yes.

This is how Vegas does a mix.

Basic rule:
Sample x is mixed with sample x from all sources fed to a common bus.
This meaning that all sources are mixed sample accurately.

A source can be the file/event on a track, the output of a filter, or
the output of a gain stage. Some sources are sequential and others
are parallel. Depends on the routing.

However, sample 1 from a source will never be mixed with sample 2 of
another source.

When a buffer of audio data is streamed into a filter, the filter
will produce output(even if the output is silence). (If it doesn't,
then by definition it is not a filter, but a renderer.) Sample 1
going into a filter eventually produces a sample 1 on the output. The
output Sample 1 is mixed with sample 1 from all other sources tied to
the main bus. If the filter requires samples 1 thru N to produce
sample 1 on the output, we wait for sample 1 on the output before
mixing with all other sources. We never mix late. We will gap
playback if we can't keep up with filters like this.

Phasing can occur in a mix scenario if the same sample is run through
different processing stages. You end up mixing the original sample
with processed versions of that sample. This can produce phasing
effects. It is dependent on the filter, the source, and the mix path.
It also depends on wet/dry mix on the output of the filter.

Using different filters on different sources that were phase locked
before processing could produce phasing effects. This would happen
with external output gear just like it will occur with plugins. It
also depends on how a filter mixes its processed data with the dry
signal. If the filter does not mix sample accurately, then you could
get a phasing (among other) effect.

Excellent! Thanks for the detailed response. Your reply [above]
raises an additional question however:

If I were to route "phase dependent" tracks through multiple and
separate output busses (i.e. 8 mono drum tracks to 8 mono output
busses) would these tracks still remain phase/sample accurate? Would
they remain such with differing DX Track processes? Would they
remain such with differing DX Buss processes?

Thanks in advance.
