[quote]Ok!
Well I got the philosophy of the thing I think, but I believe am talking about quite a different thing here...
My basic Daw( where I write everything) is Logic Pro 8 in my Mac. In (!) Logic I use an Audio Unit which causes me a big Cpu overload. So, my question is: can I somehow using wormhole make this specific audio unit that I use in my Mac, run through let's say Live 6 and my, connected to the Mac, Pc, having as result that this Audio Unit makes use of the Cpu of my Pc? The thing is that this Audio Unit comes only for Mac (and there's not a Pc version). If there was a Pc version I would do the method described as above, and wouldn't be here writing for it..
So please, if you have any ideas about if this is possible to be done or not or if you have any advice, I'll be waiting...
By the way, the latency caused by wormhole depends basically on the way I have connected my Mac and Pc? If I connected them via 1000G Ethernet I would get the best possible results and the lowest latency?
Trully thank you for you time, and looking forward for your reply...[/quote]

Jokke	Hi Tony!! No prob, nice if I can offer at least a bit of support! What you try to do is quite advanced and I haven't done anything similar. Hopefully someone else who is reading this would have some more experience. But let's start with latency. Yes, total latency can be figured out when you calculate together both system latencies, plugin latencies, connection latencies and WH2 latency. I assume that you use Windows WDM driver in your PC? Pls, check out free ASIO4ALL driver (www.asio4all.com) if you could use it for lowering your PC latency without making any HW investment? I have used ASIO4ALL when using my recording laptop as a "effect unit via WH2" for my DAW during mixing. Works well even with laptop's integrated soundcard, so I doesn't need to bring in my Firewire interfaces from recording room for mixing. Your second question is challenging. WH2 doesn't transmit any MIDI information, so it cannot be used for syncronization of two systems. It doesn't transmit any clock and/or project location data, only audio streams. So for having two systems in MIDI synch you should have separate MIDI cables for synch or perhaps you could use some sort of "MIDI over ethernet" solution, since you already have working ethernet connection for Wormhole2. Br, Jokke
tony_dab	No worries..! Ok, quite bad to hear the news fot the audio unit that I mentioned, cause it's really amazing. Anyway, a have a couple of last(I hope..) questions. First of all, as long for the latency, it depends on the soundcards that I use on each system and their settings- did I got it right? On my mac I have a firewire soundcard (with low latency etc) but on the pc I run Live with the onboard motherboard soundcard. So I guess the latency that I see when I play is because of that..? Which also means that I have to get a low latency soundcard connected to my Pc too..? Secondly, I found another vst for my Pc that seems to do a similar job to the Audio Unit that I mentioned for my Mac (basically it's a rythmic gated vst). My problem is how do I sync its performance with Logic (running in my mac). I mean that, to run exactly on time with Logic (I thought to put the same tempo on Logic and Live, but I think there is a few difference, for example 124 tempo isn't exactly the same 124 for both progrmmas, and therefore using this vst runs out of time somehow... I dont know if I am clear Anyway hope you got what I mean... Huge thanks for once more!
Jokke	Hi Tony!! Ah, now I got your question! Sorry, I'm bit slow today (well, I guess not only "today"...) Unfortunately Wormhole2 cannot do what you describe. It routes audio streams between DAWs, but all the plugins you use in any of the computers needs to be supported by that system. So only solution to your problem would be the PC version of this problematic Mac AU... Then WH2 could be used. I think latency is not affected by speed of connection (strangely enough). Connection speed affects more to connection bandwith e.g. if you use 100MB ethernet (like I do) you can use about 30 mono channels between computers. If you would have 1GB ethernet you would have possibility to use more channels, but actual latencies would still be same. Latencies are affected by latency and buffer size settings in each system. Also "normal" plugin latencies play a big role. Luckily WH2 is quite smart - it pings latencies for completed insert loops automatically and informs host SW about needed latency compensation.

Jokke	Hi Tony!! I'm working with Cubase, but WH2 principles are similar, so I'll try to offer some support. First: Using WH2 as "two way teleport" between computers is always done in WH2 insert chain mode. This mode has the automatic latency calculation system. So in your main DAW (Mac) you need to insert WH2 to the insert slot of your sequencer, as you would put your normal effect plug-in. Select it to be "Insert" from WH2 Insert Chain box. Now this insert transmits (and receives) the audio stream of that channel to slave (PC) via ethernet. In your slave machine you need two WH2 instances. First receives audio stream sended by DAW's WH2 and second sends it back to DAW. These instances needs to be "connected" which is done from pull-down menu of WH2. Pls, check manual for details. Between these two WH2 instances in your PC you can put your needed plugins which now affect your audio stream like they would be in you host machine. BTW: You doesn't need to have any costly sequencer in your slave machine. E.g. free VSTHost program works well as a platform for WH2. BTW2: For avoiding your setup entering to the world of "snap, crackle and pop" you need to adjust WH2 buffer settings according to your DAW's latency settings. Pls, refer manual for details. It takes a bit trial and error to get them properly adjusted, but after that you doesn't need to touch them anymore. WH2 keeps buffer settings stored by itself. Hope this helps! Br, Jokke
tony_dab	Ok! I read the discussion about live 6 and logic pro, and this is very nice cause I was wondering about the same thing, and trully was reluctive to find the answer ready.. But I also want to make an AU running in Logic Pro on my Mac, run through the processor of my Pc (where I use Live 6). I am new using wormhole so please explain as simple as possible, and thanks for your understanding in advance... Thank you
