Hello! I'd like to understand why I can't change the Buffer Size - which is on 256 - in my card interface. There is some arrows to change it but nothing happens when I touch them. Not possible in cubase too... to field for doing this is gray, can't touch it. I have a Celeron 2.4 GHz et 512 Mb of memory (Windows). I use cubase sx 2.0. Thanks for you help!
