Get the most from your TI

Here's a little tip for everyone out there,

The virus connects via USB as we all know,

But...... USB has a flaw.

Unlike Firewire, USB shares its bandwidth with all the other ports on the same card. (eg. PCI Card)

For a while when I first got my TI it was great, but when I had a good few parts playing together I was experiencing dropouts, I'm sure everyone has had this issue and its a pain in the arse.

The thing is that if you have, say, your TI, USB audio interface, Midi keyboard, and any other USB connectable devices hooked up to your computer together, they are all going to be sharing the same amount of bandwidth between them (if of course those ports all lead to the same card).

Something I did which really helped the performance of my TI, was to buy additional USB2 ports for my PC in the form of a PCI Card, just for my virus. Some might say that's a bit extreme, why should you have to do such a thing in the first place? Unfortunately, its the nature of USB.

USB devices cant take all the bandwidth for themselves unlike firewire, which is a real shame and hopefully will be sorted out when USB3 is available.

Anyway, I bought myself a USB2 x 5 and Firewire x 2 port PCI Card, and I can say that I am getting the utmost power from my TI beause it is the only thing I have connected to that card at the moment.

And for a measly price of about £6 for the extra ports I think that's quite good really. That money could of easily been spent on fags or booze.

If you have the extra PCI slots to play with that's always a good option to bear in mind if your virus is always kicking up a fuss when you load that 3rd, 4th or even 5th part into your tune.

Thanks for the tip! i experience a lot of drop outs that doesn't help me being as creative as i had hoped for.



If this cause less dropouts it is worth the few bucks indeed.

Yeah, I have a LOT of USB devices so it was a must for me - I didn't even have enough bandwidth, never mind dropouts.

Midi keyboards and virus on my PCI-E USB card.

Mouse / Keyboard / Webcam / Printer / Everything else on my motherboard USB connections.

USB isn't fit for purpose for an audio interface for many reasons - but these all pretty much go away when you get a dedicated device (apart from lack of DMA, which kinda destroys the taking the load off the CPU argument for using the virus...).

Well, tell this to RME who just released a USB version of the Fireface that has better latency than the Firewire FF400, according to them :)

I could believe that RME's new interface does have better latency than the FF400, and in reality USB2 technically can transfer at a higher bandwidth than firewire but like i stated earlier, if you have like that new RME interface and even just a virus runnung from the same USB PCI card then the bandwidth will be divided between them.

If you have a dedicated PCI for a virus and another for a soundcard your laughing!

Latency is a different kettle of fish to bandwidth and CPU load...

I don't actually know which of Firewire and USB have inherantly better latency, but i'm sure the quality of drivers have a lot to do with it, too...

USB no doubt. I bought the FW epansion for my Korg M3 and jeez what a crap add-on that is! just couldn't get rid of the latecy and i am not the only one. The entire karma forum is filled with unsatisfied people.

USB on the other hand always works perfectly as you can see with the Virus.

(to Prolodic) : have you ever load the same project ??? and was it different?
