HDX and HD 44.1 and 48k in and out latency?

[TNM]

Hi, all the figures on avid's site are for 96k. I don't know why they won't provide figures for lower sample rates.. Using a ton of outboard digital midi gear, there literally is zero point in me using 96k when composing.. 96 k is not going to do anything for an old 31k rompler for example.. yes i have a couple analogs where it would be beneficial but not worth the overall overhead until i get a more powerful mac.

I have been using an apollo system with PT vanilla so i can monitor everything of my outboard in realtime, avoiding the PT mixer and going through UAD fx.

I am now tired of the 32 input limit and the only way to move on from this is HD.

Either hd native with an avid or 3rd party (i.e antelope) hd compatible interface, or a HDX system.

Now, what i would like to know is the latencies of monitoring through pro tools for both these, at the lower sample rates. Let's just use avid interface figures as 3rd party i/o will have different but negligible converter latency. But for sake of uniformity and ease, let's use avid for this example.

The other thing is, someone told me that each plug in instance in HDX adds latency to the monitoring path. Is this true or not? They told me it's the case even with zero latency plugins. If so, the apollo is a superior system and a shame i can't use 64 ins. And if so, to get the HD software, i might get a hd thunderbolt native, and buy an antelope orion HD to connect to it, which like the apollo has it's own dsp mixer with fx, so even in PT hd i could totally avoid monitoring through pro tools. Antelope has a special pdc driver that lines up sample accurately when you record through it with PT HD... it's very impressive when watching the video.

Thanks in advance!!

Wow it seems there is no way to contact avid support to ask them this without an active service plan or paying for an incident? Isn't there a pre sale place for home users that have upgrade questions? Weird!

Here's the HDX specs: http://www.avid.com/products/pro-too...specifications

Now I really am convinced people don't even read topic headers...

Those specs only tell 96k, which was an entire point i made in my post, as well as topic header.

Is there a reason avid won't disclose the RTL at 44 and 48K? This is getting a bit suspect. I do NOT believe everyone with a HD native and upwards uses 96K.

Actually, it was that I didn't read the addendum at the end of the article I posted..

Sorry.

no need, i was just frustrated, i am actually the one who is sorry for snapping. Uncalled for. please accept my apology.

Not if they're AAX DSP.

interesting..

did aax dsp change from previous hd?

here the moderator says each dsp plugin adds it's own latency

Also, as you can see in that topic asking the same question 3 years back, no one answered..

Such a shame that no one with HD native or HDX will get the figures.

Low latency mode in HD native is of no use to me cause you can't use fx monitoring.. However with an antelope interface it might work out cause antelope have their own mixer with dsp effects.

If AAX dsp does NOT add latency into the monitoring path, that is a HUGE boon for me and HDX starts becoming more interesting.

Really, with HDX i could replace entire outboard mixers and use pro tools AS the mixer for everything.. integration would be great.. and personally, many of those aax native (and dsp plugins) are just as good as any uad plugin.. take plug in alliance bx room for example, it's an incredible reverb.

EDIT:
ok, it's unusable for me..

3x 3rd party dsp plugins in the monitoring chain would add 4ms latency! WOW!

The point of HDX to me is not having to bounce to audio! Well one of the points!
Does it at least do ADC on the live inputs that you monitor with DSP FX, so it plays back with rest of project in sync?

But even monitoring through an eq, comp and verb would cause monitoring latency issues at 44.1 and 48k

In fact, since there are many true 0 latency native plugins, i think a hd native at 32 samples would have less latency when monitoring with multiple plugins!

What plugs are you using that will have 175 samples of latency?

Latency needs to be managed regardless of what kind of system you're using, but an HDX rig is capable of very large high-sample rate sessions with minimal throughput latencies without having to crank buffers down to unstable levels, as long as you manage what kind of plugs you're using where. A native rig is capable of very low latencies as long as buffers can be kept very low. This topic has been discussed ad infinitum here, but maybe these posts might help you?
