Loading downloaded patches into the Virus.

let me just copy the answer from the internal virus forum:
http://virus.info/forum/index.php?page=Thread&threadID=2590

You have to copy the files (.mid) to the install location of the factory presets.
On a mac this is in /Library/Application Support/Access Music/Virus TI/Patches (please note that this is in the ROOT folder/library/App... it is not in USERNAME/Library/... I searched for the folder, found the wrong one and aksed myself why it didn't work)
On Windows the location is "My Documents/Access Music/Virus TI/Patches"

Cheers,
Barely.
