Got to share my excitement!
Bought the EW04 Expansion Card and was a little disappointed with the sounds as there is a lot that I would not use.
HOWEVER I recently discovered a transcription of the Aria from Villa-Lobos' Bachianas Brasileiaris No.5 for cello and and soprano voice. Set up the KN7000 with Cello soloist Left voice, FemaleAh Soloist Right1 voice (EW04)and Concert Strings for Right2 voice. With a little volume tweaking it sounds absolutly brilliant. Well to my ears anyway!
