Alles anzeigenDear A,
Against your statement here this is not a general problems with the Virus TI at all. Especially if the unit goes out of tune stand-alone and is not connected to any other equipment via the TIs Midi In (so that Midi clock could be send to the TI) or via the SPDIF in (so that any digital clock change could be send to the unit).
Does the unit do this also on your computer setup if you do not use the Virus Ti Control PlugIn?
And concerning your problems when the TI is connected to your Mac Pro setup:
- what is the audio buffer size currently set to in the Logic audio preferences panel?
- what is the "process buffer range" set to in the same preferences panel?
- is the TI used as the audio interface or which device is used for this?
- what other USB devices are connected to your Mac setup besides the TI and mouse/lkeyboard?
- to which USB port is the TI currently connected?
- and last but not least: have you exchanged the USB cable to exclude this possible source of error?
Best wishes,
Jörg Hüttner
I´m sorry to say that. But it is a general problem. I bought my 
virus 3 years ago and since access is releasing new drivers it´s getting really bad. Virus shuts down. Virus not detecting in the New Mac OS (10.5.8). During producing it looses the USB connection and so on. I´m really dissapointet too.
I mean a synth wich costs over 2.000 euros should work without any problems and should not be effected off any other usb devices.... I mean you guys are not the only one with usb synths and controler. And actually i have different software synths wich sounds even louder and better than the TI. sorry to say that. but it never worked clean. NEVER.
PS: And the on/off button for the TI is a pain in the ass too.
Any ideas for me. I tried all the things you wrote above.
