For this software (2 things actually) to work, it seems (from successfully installing on Linux with Wine for the Virus software), you need to install the Virus software (anywhere) and then either install the OsTIrus vst or just put the vst in the right folder and find it inside BItwig (I already had it in that folder, so even though I did install it from anther deb, maybe I didn't need to).

Then you go into the Program Files/Access Music/Virus TI/Common folder and copy the firmware.bin file and paste it beside the OsTIrus vst you're finding in Bitwig. Then it will work (ie it worked before, the vst loaded before, but it didn't have any sounds, and now it should have all the TI sounds. I guess the firmware.bin directs it to find where all that is on your harddrive?

You can read the next post here to see how I got it to work on AVlinux.
