Current System Limitations
Question for all you folks that have done the HD9 upgrade...
At present, my mix-room system is a Nahalem Dual Quad Xeon, HD|6 (PCI Core and 5 PCI Accell) by way of a Magma PE6R4i chassis, and 32-fader D-Control. The only outboard I'm using these days is the System 6000 (still can't be convinced that the plugin sounds anywhere near as good...) I work almost exclusively at 96kHz, and when I get stuff in to mix, I usually upsample to at least 88.2 or usually 96k because I much prefer the way the mix bus comes together in that environment. I quite often mix records in 5.1 but mostly monitor my stereo downmix for balances, and often times the label doesn't even know they have 5.1 mixes on their drive. I do this because I enjoy it, and when a surround release becomes viable for that artist, there's something in the can that was created when the song was fresh. Anyhow, I'm often frustrated with the 96-voice limitation at 96k, and often end up sharing voices around so that I can properly have things on their own rails. Problem is, of course, once you've assigned explicit voices for things, they can only have TDM plugins. Now, even with HD|6, I'm always hitting the wall with TDM horsepower, especially when I start sharing voices around. The CPU meter is hardly ever above 30%, even with tons of MDW eq's, AutoTune EVO on tons of BG vocals, Waves SSL stuff, etc., all running RTAS My question is this. If I do the HD|9 upgrade, and run my mix on the native mix engine, using core audio for I/O, will the CPU complain substantially about having to build a complex mixer with many 5.1 Busses (Drum Sub, Drum Backbus, Band Mix bus, Vocal Mix bus, Surround Reverbs...)? It seems that I can cap out the TDM cards VERY quickly with plugins, but I can toss RTAS stuff on for days, and barely even hit half way... Does the routing side of the ProTools mixer require a lot of CPU? Basically, I need to somehow overcome the bottlenecks that I have now, and I'm hoping that buying a 12-core beast and going with a Native mix engine, that I can go beyond the TDM maximum I'm currently stuck with... If I was to use the Native playback engine, can you still access the I/O for digital hardware inserts (my trusty System 6000)? While I don't particularly love the idea of having my TDM cards sitting idle, I just need to get work done, without wanting to stick a fork in my eye... Do I have to buy an HD Native card, or can I use my existing hardware? Aaaarrgggghhh... Too many questions... Thanks, in advance, to anyone who's knowledgeable on these things..!.. Cheers, eh? |

Re: Current System Limitations
Hate to burst your bubble, but all hi-end versions of PT9 (HD TDM, Native and CPTK) are still limited to 96 simultaneous voices at 96kHz. See pages 11&12 here:
http://akmedia.digidesign.com/suppor..._v90_69545.pdf So you'd get nothing out of it at all, except possibly maxing out your cpu. And using the core audio drivers for HD hardware is limited to 8 channels IO on HD interfaces, although I don't know how this affects D-control. |

Re: Current System Limitations
Avid should up the number of voices for HD systems.

Re: Current System Limitations
It's currently limited by the TDM hardware - that's the entire point. They've enforced the limitations on the native systems purely so that they don't suffer a TDM users revolt (although they kinda had that anyway with PT9 - you've gotta feel a little sorry for them).
Until we see new TDM hardware cards with massively increased voice counts we're stuck with it. |

Re: Current System Limitations
What are the voice limitations in Nuendo? is the limit determined by the CPU power? may be it is worth locking PT to a Nunedo rig to up the voice count. I am getting a new computer (whole new system) and I was thinking to go PTHD native (to lock to my HD2) but may be Nunedo is better for voices.

Re: Current System Limitations
I think I would give a try to 44 or 48khz sessions. You would have double of everything...

But at 48k, the air is gone. Melodyne and other plugs seem to breathe more at 88 and 96k. It's a more accurate capture.
That, and 96k is the major label standard for archival. And, to the OP, you won't be able to share voices Natively.

Re: Current System Limitations
Really? In that case 48khz and 96khz mixes should not null, can anyone prove that to be true? I only track and mix at 44.1 so I cannot easily do it my self but I would be interested to know if this is for real or if it is one of these things people tend to imagine.

Recording at a delivery sample rate is a personal choice. To me, 88 and 96 sound more open.
Anything with flange/chorus/time-based effect stuff will never null, and I don't care about nulling. I care about the track. And to answer my own sig - it does help the chorus. It's a game of inches, people.
