Sav,

Did this enable you to edit the JV in realtime? Could you tweak the sounds using SoundDiver while the JV was playing a midi sequence initiated by Cubase?
I've got a soundblaster S/C and I couldn't get it to work. I was using hubu's loopback to get the programs to share the serial port (I've got the cable) rather than the S/C's midi port. Maybe this is why I couldn't get it working?
To be honest I was fumbling around a bit and found it all a tad confusing. I could have set it up wrong.
In theory, is it possible to have Cubase and SoundDiver runing together, and be able to edit the JV in realtime?
