Hi, I use a copy of V3 on my PC too. Best you get all updates, install it from the CD if its not the last version you should do the following steps first (I highly recomment this, as you will get in functional troubles without V 3.0.5.4. installed on XP SP2) - install update to V 3.0.4 and than overwrite the prog../emagic/sounddiver directory with the last version V 3.0.5.4 files - than it should work with near every MIDI interface (except behringer BCA2000 stuff that would not work at all). I use it with my EDIROL UM-880, and it worked fine - till windows did not longer recognize its MIDI ports - typical MS shit. A list of supported synths is on the original CD - a PDF file with 8MB size, so I could not post it here. Good luck with your Diver, Markus. p.s.: another tip, never answer search for or something like this to a box opened by SoundDiver at startup, best you try skip or try later (dont know their names in english), in most cases the other way will take you to a "simulated HW" mode, and you get no working connection to your synths.
