Does this mean that some plug-ins will be able to use two chips? Or they simply will not work on 96 and higher?
Thanks,

Yes, you can get 3 instantiations per Mix card as long as nothing else, such as another plugin or the Mix Engine, is using an SRAM chip.

Reverb One manages to get one instance per chip at 96k and 192k by downsampling signal to 48k and then upsampling again (the reverse of the upsampling/downsampling technique discussed on another thread). This is only done for the wet channel; the dry channel stays at the higher sample rate. I can't say I am terribly proud of having to do this, but otherwise there would be neither enough memory nor enough processing power for it to run at the higher sample rates. This technique actually works very well for this plugin.

DVerb is true 96k. I am not sure what 3rd parties have out.

[dstagl]

Would it even be possible to release a plugin that could span multiple chips? For example, Reverb One if you wanted it to run at 96k or 192k. Is that a whole other ballgame in terms of hardware?

So if the new chips are 20% more power. Does say reverb one at 48k use the whole chip or does it leave the other 20% to be used by say D2 or D3.

dstagl-

There is nothing in the hardware that prevents plugin from spanning multiple chips; it is a software problem. The software issues start getting pretty complex when you have to take into account dsp shuffling, but we will probably be looking into adding this soon because of the need to support surround reverbs at high sample rates. Several 3rd parties have been bugging us about this for a while.

davemc-

Reverb One uses the whole chip.

[Extreme Mixing]

Why not just use one chip per "side" of the reverb? I suppose one chip would have to run the control panel.

So then as of right now there is no true 96k reverb plugin for Protools?

Are all current 3rd party plugins available for MIX systems compatible with the HD systems? Do any plugins require a software update in order to function? This is assuming you still keep your session at 44.1k or 48k of course.

Not quite yet. The majority of them are, though. All of them do require a software update, thought the changes are minor. according to Digi.
