As stated above, I purchased a new soundcard with my new DAW - a Creative XF1 Titaium which I had preinstalled to eliminate future problems. Everthing is working well - still a lot of Creative Bloat Ware, some of which I will probably delete. I loaded the exras and ticked the list to download and included the Sountfont Manager program. Typical Creative - it didn't download and I had fiddle about in their Website to find the program to download and install.

I have a number of DX Plugins which have been set up, but cannot be read by RealBand. The VSTi version are however working OK.
