Network/Firewire Audio Linking
So one of my more utility-based ideas for a patch has been to give me the ability to use PC VST plugins via my Mac’s sequencer (Cubase 4 Studio).
I haven’t researched it too much, but I’m under the impression that the netsend objects probably only work with control data. If I’m wrong, what’s latency like? Is it possible to use firewire to network a mac and a PC, and get max to recognize that network?
I also need to look more into the VST object helpfile/spec – if it’s possible, I might make Max Patch replicas of the VSTs I want to use, so that I can get control over them without needing to hook up a keyboard or mouse to the PC.
Anyway, any thoughts on the idea would be much appreciated. I expect this is going to be a tough undertaking, and I honestly don’t expect it to particularly well even if I do get it working – but I’d like to try.

I know that sending audio over a network with netsend or udpsend or any other currently available max object is not possible.
Don’t know about drivers that allow for low-latency networked audio though (would surely be interesting). If such a thing exists I can imagine it should be possible to do something smart with an aggregate device and soundflower on mac.

Apple AUnetsend & AUnetreceive (AudioUnits, not VST’s though) do
So they’re usable for streaming a Logic Pro mix to the stereo in your

I don’t have personal experience with this, but can JACK not be used across a network connection?

On OS X, it *used* to support this – it broke in later versions
On Linux, it definitely is supported:

That’s too bad. I wonder if the latency would be less than with AUNetSend and AUNetReceive. I assume so…

I had toyed with the idea of using the AUNetXXXX units, but since I need it to be interacting with a PC, I doubt it would be very useful – I’d need to write PC interpreters for it (unless someone has already done it?), and as was mentioned, it seems latency is terrible.
It seems like the ‘best’ option, latency and ease-of-setup wise, is to do the audio connections via analog connections. There are issues with that, such as the fact that I’d need an input/output on each machine for each mono signal I needed – essentially only one VST plugin, unless I went out and bought another couple of ADA convertors. And, then there’s the fun of losing sound quality, and syncing everything.
Hmm… Though… I suppose it’d be possible to do it via one set of connections, and when I need to record each track, just solo the VST I’m recording.
While I don’t have an intel mac (yet), the other thing I’d like this patch to be able to do is communicate between Parallels Desktop and Cubase – Does anyone know how Soundflower/Audio Hijack Pro deals with Parallels? Specifically, the ‘transparent’ windows-application-launching, where parallels hides the windows desktop.

If the computers all have soundcards/interfaces with ADAT I/O, then that would be a good option–keep it digital. Or if you only need two channels both directions, you could use s/pdif connections between them. If you use the digital connections for computer to computer transfer, then the analog I/Os are available for getting signal in and out as needed.

Well, my G5 has the optical jack (And I do believe it’s a seperate jack, not built into the headphone port) – but the PC has a coaxial SP/DIF connection.
While outputting to the Optical port on the G5 would be pretty nice, since I don’t currently use it for anything, I’m not sure I like the cost of buying an optical->coaxial convertor. Are there any available for under 100 bucks, that do two way conversion?
Actually, never mind. My mBox has coaxial Spdif i/o – however the PC only has spdif output, not input.
