At the risk of flogging a dead horse...RE: RTD W 2 BUS PROCESSING IN PT

[recall]

I am mixing a record at the moment. Tonight I was preparing to upload a few songs for the artist and label to listen to while I complete the rest of the mixes next week.

When I listened back to the Bounces I definitely felt they were different from what I was hearing.

Now I know the whole debate about BTD V. RTD so I don't wish to go over that again I just want to double check a few things.

Those of you who use RTD with mix bus processing, how do you set it up so that the mix bus processing records to track?

I can only think of one way involving two stereo auxes.

So here goes:

set up a pseudo 2BUS with usual 2bus processing such as AC1/CSPRO etc bus all my channels to this.

set the output of this bus to the input of bus 31/32

then set up a stereo audio track with input set as bus 31/32

Is this correct or am I missing something?

I know this is like PT 101 but I always figured I was missing something using two auxes for this method,

If I use just the one then the audio track will only record whats going TO the bus not what is coming OUT of it (processed mix)

Correct??

Yeah youzegotta set up a bunch of busses or use a master fader on the bus.

There is no difference in results RTD vs. BTD. They null.

I RTD because it offers an improved workflow.

I have tons of busses and master faders in practice.

I kind of agree having tested this months ago, but this time it really didn't sound the same. I'm gonna do some null tests tomorrow.

[peeder]

If you have modulations running, your takes might not null if the modulations go out of phase (e.g. LFOs, chorouses, etc.). And there may be random elements in some of your plugins etc. So make sure two takes of the same method null as well.

There may also be dither differences RTD vs. BTD you have to be aware of. To really stamp your test as definitive I'd have to see enough to replicate it (including the prefs panels, etc).

If you find a reproducible difference we can submit it as a bug report. I have never seen or heard of a reproducible difference; the one time someone uploaded files they swore were different they in fact nulled down to dither.

Nearly all of us would claim bit-identical files sound different in a blind test. It's OK. That's part of the challenge with audio. It's a moving target.
