Hi,
overhere [url="http://www.soundsderhelden.de/soundsderhelden.html#vb-99"]http://www.soundsderhelden.de/soundsderhelden.html#vb-99[/url] you can find (for both the V-bass AND the VB-99) files with some awesome sounds ... especialy for the V-bass you can find some great sounds including about 5 sounds created by (or for) Alain Caron.
You can find files for PC and for mac ... easy to install using sysex streaming.
Have fun!
Cheers,
Harry.
