I really do not like to be a pain in the ass...

Of course not...

Could you tell these people, that incase it does not happen when the synth is connected to a MAC - and every finnish trance producer I have shown the issue have agreed it is going offtune - it must be a fault in the synthesizer.

And you did this as a double blind test and not a 'can you pretend to have good ears competition'?

You also mention that it occurs with resetting the mixer... So let me get this straight - you reset the mixer and get a glitch... I wonder...

Also, you say it does it with other VSTs.... you mean ones that interface with a piece of hardware via and delivers audio via a USB driver? I have loads of VSTs like that...

So far I have heard nothing that persuades me of anything more damning than one or two samples dropped or a little variation in timing between cubase the outside world when you reset the mixer (which, incidentally i assume is supposed to flush buffers or reset starting points - the discontinuity from which is more or less guaranteed to generate artifacts in spectral analysers which in there nature operate over a series of samples to offer the kind of pitch resolution you are angling for (5Hz spectral resolution requires 8820 samples at 44.1kHz or 20ms, so you need longer than that to detect deviances of the orders suggested here, let's say at least 10,000 samples).

However, i'm sure the waves plugin works in a slightly more complex manner meaning it retains this deviation due to dropped samples or a slip in timing between cubase and the real world due to the mixer reset for longer than you might expect...

But, that's just a theory based on the very little evidence provided....

I always thought it was my fault, some kind of acoustic phenomena in my room... you shouldn't even need any analyzers, you can clearly hear that there is something going on, however even the vey basic Cubase Tuner plugin shows that it doesn't hold the frequency, sometimes A3 is locked at 440 Hz, and then again it's sliding between 435 and 444 Hz which is when you can hear that it's slowly going up and down and left and right... i can also actively trigger this behaviour too by doing the ASIO reset.

It doesn't sound like analog emulation or phase shifting, but even if it was, why would that only happen sometimes, ie it's holding the tune fine for 10 minutes, and then all of a sudden analog emulation and/or phase shifting kicks in? Doesn't make much sense to me

Ok, I have exactly the same problem, but on Mac. System : Mac pro, Snow leopard 10.6.3. Drifting of around 1/10th of a tone, enough to be noticeable by ear, and quite uncomfortable. BUT if I use the analog outs of the Virus ( Virus snow here), no more pitch drifting, it's super stable. I even did a fresh install of OSX, only installing logic and the virus software, same problem. Happens on Logic studio and Ableton Live, on every sound card I have ( Orpheus, internal mac sound card, Virus as sound card), and at every buffer size.
I tried on a Macbook pro, Leopard 10.5.8 : no problem at all, pitch is stable.
I did all these tests using the Init patch, with the balance to the left ( only OSC1 then).

I've also noticed some pitch anomalies with Logic 9.1 in OS X, usually the virus is one semitone off sometimes.

lol @ robg,



installing an OS has nothing to do with a virus shifting.



So thats why i always seem to have mixing problems using the TI virus!

My offer to buy all of your terribly flawed Virus TI for 30 bucks each is still valid. Of course, I'm not going to pay more than that, since the bug is terrible and prevents pro music making.

That has be the reason why so many professionals use the Virus with their Windows-based computers but they never release tracks with it on them.

Ive returned my ti2 back to dealer with a sync/detune problem. It will be interesting to see what they say with this in mind. Access have told me a ti2 and laptop running windows 7 is a no go, but on a mac everything is fine. We cant all have a mac and they should let people know if its not compatable, before they commit to purchase one.its disgusting!!!

I never said that it did? I was pointing out the fact that I'm on the Mac platform (OS X) which is relevant to this issue.
