...My question for you is why do you use the Creative ASIO instead of the Virus USB ASIO driver? My understanding is that you cannot use two different ASIO drivers simultaneously--it's a limitation of ASIO implementation. I'm not implying that you are trying to use two drivers at the same time, I'm just noticing that because you have to choose a single driver, you chose to use the Creative ASIO driver. So if you are not using the Virus USB ASIO driver, then you are also not using the intended full feature set of the Virus TI. It's not really fair to say you have a 'golden setup' if you aren't utilizing the Virus USB ASIO driver.
It's great your setup works, though--thanks for sharing.
#1 You do not need to use the Virus ASIO driver to use the USB inputs from the Virus - the VST handles them.
#2 I use the Creative ASIO driver to get all the analogue inputs from that sound card,too.
#3 If you use ASIO4All you can, in effect, load multiple ASIO drivers held under one umbrella ASIO driver - But I wouldn't recommend it unless you have a very good reason to.
I am making full use of the Virus feature set whilst also using the Creative ASIO driver - I'm curious, who said you must use the Virus ASIO driver to do so?
Unless it's your only good sound card (e.g. laptop or something) I really wouldn't recommend using the Virus ASIO driver, as I hate to say it - it kind of sucks using the Virus whilst using it, use something else if you can.
Also, that is probably the first time I have seen Sonar (what a messy eye f@#k!)... Is Sonar a supported DAW?
