Hello AdDeRoo,
unfortunately b3v1 presets can not be converted to b3v2 for now :With same drawbars/percussion settings, the sound is radically different, same goes for FX.
In the meantime, in analog lab 4, you can still use b3v1 user presets. you need to tick the option "include legacy products" in the main analog lab dropdown.
Hope this helps a bit
cheers,
