The new OS version includes a new control centre application for Apple Mac OS X and Microsoft Windows XP and Vista. Using the stand alone application users can overwrite the ROM patches of their Viruses with their own sounds and perform complete memory backups for safety reasons and archiving.
OS 2.7 furthermore increases the amount of audio streams from the TI into the Virus Control plug-in by 50% and adds input side chaining capabilities. This way, users can send audio from the host sequencer into the Virus' sound engine all digitally, process it with the TI's filters and FX and finally loop it back into the sequencer.
The new operating system also increases the amount of ROM sounds to 26 banks with 128 patches each (that's, including the RAM banks, a total of nearly 4000 onboard sound patches). Among the new patches are patches by Dean Coleman, Stuart Price (Madonna), Numb and many others.
Pricing & Availability OS 2.7 is available to every Virus TI user free of charge and can be downloaded in Spring 2008.
