Latency issues with Access Virus synths in Cubase?

I had been planning to get either a Virus Desktop or a Virus Polar in the next few weeks, but I see a LOT of Virus owners say they routinely bounce or freeze their Virus tracks as a normal part of their workflow, whereas I consider those operations something you only do to free up CPU/improve performance.

I’ve also read that the Virus synths seem to work better with some DAWs than others (apparently there are/were some well-known issues with Ableton Live, for example).

So I’m curious- if you own a Virus synth, how well does it work with Cubase? Is there noticeable latency when tracking parts? This is my biggest concern; I generally don’t mouse parts in- I play them live. And I’m very sensitive to the latency between hitting the keys and hearing it in the headphones. On my current setup, I don’t feel any noticeable latency when playing VSTis with my keyboard controller, and there’s just a tiny but acceptable gap when playing external non-USB MIDI devices from the controller. I’ve never used a modern USB-based external synth.

I’m also curious whether there’s any sort of noticeable latency difference between controlling a TI Desktop from a MIDI controller versus playing the built-in keyboard of a Polar? I’m kind of leaning toward the Desktop since I only have room for one keyboard and I love my MPK49. But I’d get a Polar if I thought there would be a reasonable improvement in live performance.

I own a Virus Snow and Cubase 6.5. I can tell you that it was a nightmare to get them to work together. First of all get an account at http://virus.info/forum/, there you will get all the help you will need.

The big problem with Virus was “pops and crackles” during playback. The support recommended me to buy an external
USB - hub that was powered and supports USB 1.1 (http://salestores.com/belkin57.html). After that my Virus is stable.

The latency problems you talked about is not from Cubase, it comes down to which sound-card you have.
All DAWs have this problem, its NOT DAW related. I read threads from Logic, Cubase, Ableton that experienced this problems. I have an custombuild PC. I use a MIDI controller for the Virus because it doesn’t have a built-in keyboard.

Btw, there is a new operating system for the Virus (OS5) but i would not recommend you to install it since a lot of users experienced a lot of problem. Wait for the fix.
