If it possible, set in your DAW master sync clock as Virus MIDI device. It works on mine.

Oh, sorry Marc. I have read not enough carefully, so I missed it a little.

Now we got 3 topics about the same problem. Read other topics and you'll figure out that you are not alone. It seems there is a huge problem with Intel Sandy Bridge system - driver works not properly and there is no matter what buffer size You will set.

Guys, look at this threat:

http://virus.info/forum/index.php?page=Thread&threadID=3693

The main problem is: Virus MUST BE alone connected to the ONE USB controller. The front panel of PCs not always is connected to the SECOND USB controller ports on motherboard. You have to check it in device manager which controller Virus use.

I have checked configuration Virus -> Belkin hub -> PC. So, when Virus is connected via Belkin hub or not - it makes no odds. Sound isn't clear and I hear some "filtered" crackles. If I'm lucky, sometimes Virus start very well and sound is clear without crackles. A driver troubles?

Hello Flabberbob!

Thanks for replay.

My motherboard has only USB 2.0 and 3.0 ports. All external devices such keyboard, mouse, Bluetooth, etc are connected to external hub Belkin F5U237v1 7-port. If my memory is not wrong, I have tried to connect Virus into Belkin hub alone, but without any good results. I will try to do it again when I'll get back to home.

Virus -> Belkin -> computer first USB controller
Other USB devices -> computer second USB controller

Cheers!

Hi Andy-Robert79!

Thanks for your guide. I've got similar experience with Virus TI. First, I have to apologize you for my bad English. I'm here because of my problems with Virus TI and not good Access Staff Support at all. Maybe my English is so bad OR they are don't read carefully e-mails... Don't know. I have put below e-mail which sent to Access support with explanation how I managed my main Virus problems - Windows 7 64-bit couldn't detect device on Intel Sandy Bridge hardware system.

There are my two cents worth (copied from mailbox):

- Beginning of quote -

As I said before, there is a small guide how I have resolved my main problem with Virus TI - very bad sound on ASIO driver and device detection problems.

First time, I made some tests on old system LGA775 socket with Intel G41/ICH7 on board.

I had connected to computer devices: Virus, keyboard, mouse. Virus was detected properly without any problems, but played with occasional "spikes". I figured out that my mouse was "spikes" generator - when I touched it then "spikes" came up. "Hmmm... Weird." - I though. So, I disconnected Virus from the old computer and plugged it into my computer based on Intel i5 Sandy Bridge platform. Of course, Windows 7 (installed from scratch) noticed me that couldn't start device (yellow exclamation mark) - "Damn, not again..." Next, I disconnected all USB devices: keyboard, mouse and Virus and connected ONLY Virus - no exclamation mark!! The important thing is here that I not used any USB hub. I connected Vrius directly to the computer (USB on back panel). Afterwards, I put in the mouse and... wait! No mouse in device manager! What the... With the keyboard the same thing happened! No keyboard!!

Virus connected to Belkin external hub:

Conclusion:
- alone Virus connected to build-in hub controller - works!
- Virus with keyboard or mouse - not works!
- Virus with ONE low USB usage device - works!
- Virus with TWO low USB usage device - crap, Virus with exclamation mark!

In my case, my computer based on i5 SB have 12 USB ports and two USB controllers (6 USBs each). First four are located on back panel, next two have one USB connector located on the motherboard. I have discovered that the second USB controller (6 USBs) has 3 connectors located on the motherboard too. So, there are 4 connectors for additional USB ports: 3 linked to the second USB controller and 1 to the first USB controller. OK, the point here is connect all USB devices to the first controller and alone Virus to the second controller. This configuration makes Virus device detectable, but I don't know why it works in this way.

Virus connected to the second controller via port located on motherboard:

and generic USB hub properties:

Finally, Virus works very well, but NOT perfectly. What problems still are here? Although it works on USB controller alone, there are still exist glitches - sound it's not clear and I hear very quiet deformation (it's NOT distortion, it's similar to hard filtered "spikes"). I discovered that when I switch buffer size (no matters what size) in ASIO control panel few times (NOT sample rate - doesn't work this way), Virus will play clearly at least. Yes, i checked what Abelton Live runs now. On Renoise I have much better quality sound than on Ableton Live (the loud "spikes" still hear here), but I know issue. On Renoise I use MIDI Virus TI Synth as opposed to Ableton Live which use VST TI plugin. On Renoise TI system works badly too, so I gave up on it and use external MIDI Virus TI Synth (Virus works as external audio device). I HAVE NO CHOICE.

Yes, there are still many problems, but my main I solved in some way... Access Staff, has to check what is wrong with Virus USB interface, because I'm not alone with my problems - check your forum, because there are another people with the same mess.

Maybe OS5 will bring some breakthrough?

- End of quote -

I'm sure the problem with Virus TI has two faces (two sides of medal): first - new Sandy Bridge platform and new USB controllers' chipsets, second - hardware problems with USB interface implemented to Virus. I think there are some "unpredictable" glitches and unstable behavior witch appears randomly and because of it it's hard to trigger it if we don't know what the ground is...

I hope Access Staff will give us ultimate solution for our problems. So good device and so many troubles. It shouldn't never happen!


Best regards to all of you,
