Pro Tools 9 Hardware Insert Delay Compensation with Lynx AES16e and Aurora 16

[LittleJohn]

So what does automatic delay compensation mean ?
Pro Tools 9 claims to have it. i would have thought it meant the ability to figure all that out inside the app, and JUST DO IT>

what then , does it mean ?

When you go OTB Pro Tools does not know the latency of various 3rd Party AD/DA converters or effects devices, therefore it needs to be computed and entered into PT so it can play back with sample accuracy. If you use Avid hardware, this is apparently done for you, hence the ADC. I like my Lynx converters and wanted to ensure they were compensated for properly when going OTB to do external processing.

This seems like quite a PITA compared to other DAW software?

Am I missing something here?

With Cubase, Studio One, Reaper, Sonar X1 etc it all just "works" and there doesn't seem to be any upper limit to what it can handle.

Or,,,,,,

Are these other DAW not handling it correctly and PT9 is?

[SRS]

Logic has a ping feature in which you simply click a button and it tells you the round trip latency amount in samples, when using any hardware. It is more difficult in PT 9 for sure when using 3rd party hardware.

LE 9 still isn't pro tools.

There is no more LE. What are you getting at?

That's just marketing buzz. It's still LE by all accounts. It's not HD by a long shot, and HD is the only "real" Pro Tools.

Honestly, to have ADC for plugs, any interface, and the option to change the pan law helps a lot. IMO PT9 should not share the LE label because things have very much changed in some key areas.

Now back to your regularly scheduled program.

It does everything HD does, without shoehorning you into Digi/Avid hardware, with a few MINOR exceptions. I'd rather be able to use my choice of converters without jamming cards into my Mac and set a 1 time delay comp setting. Once determined, it's a super quick and easy entry.

No , in some cases , HD isn't as powerful as Pro tolls 9 with a good computer .

Like the last time I had to bounce down a load of plug ins on my mac 8 core with pro tools 9 to even get it to open in HD3 system .

It doesn't do what HD does. Does it have full delay compensation? No... Does it have full plugin link-ability? No... Can you use TDM plugins? No... Does it have as many no latency output monitoring channels as you have outputs? No... I can go on and on.

YOU are talking about and external unit hardware unit like a reverb W/ Avid HW interface Yes ?? I have an AVID OMNI and use those A/D D/A 's... When I use my hardware M7 reverb And display ADC in the session it reads 533 samples in that channel and has that amount of compensation showing on the rest of channels So it does appear to indeed be compensating for the external hardware insert. Do you know if this is stated somewhere in the manuals I've looked but haven't found it. Thanks Kev

We all know the two versions have differences in some features but by and large they are the same and the gap continues to close.

Am I reading this right? The lynx via it's aes card is at least the equal of avid hardware going through the hd native card or hd1 card, at least in terms of latency? That may have settled some things for me.

Did I miss something?

Actually, the delay compensation is exactly the same as HD. In HD you can't alter the delay compensation - the thing is, you don't generally need to because the program can see what conversion you're using (192s, HDI/O etc). Likewise with PT9 non-HD - providing your converter is connected directly to the computer (eg a Lynx Aurora with FW card) then there's no issue.

The problem comes when there's a standalone converter involved (or if the driver incorrectly reports the latency, which to be honest is a f-up on the driver manufacturer's part) - PT has no way of knowing the converter latency then, and really needs a box where you can manually offset, like Logic does.

So - PT9 is exactly the same as PT HD when it comes to delay compensation.

Plugin linking? no idea what specifically you're referring to, but PT RTAS plugins are functionally and sonically identical to the TDM equivalent, unless the manufacturer deliberately gives them different features.

monitoring latency and TDM plugins? well no, but by that argument every native DAW is an LE version, since PT TDM is the only one that has these features (ignoring Pyramix, Sadie etc for now).

you can only link plugins in HD or 9 with CPTK (ie. linking band in REQ6 on 4 track at a time, you change one, the other 3 change in real time)

Ah yes, I remember now - rarely use that sort of feature so it's not something I miss in straight 9.

There's other features of course - automation changes, VCA faders etc - most of which aren't present in Logic, Cubase etc so I guess the argument still works - if you consider PT9 "LE" software then so are these packages.

A more valid argument would be things like limited IO, track count etc.not that it's going to affect the vast majority of people.

Thanks SRS! Having recently aquired the same Lynx Aurora 16/AES16e setup to use with Pro Tools 9, your post saved me the effort of figuring out the Insert Delay settings. Much appreciated!
