Seems it happens very little here. I think Oxe is worthy of more attention than this, althogh I've just begun to look at it myself. It's possible to download a modified bass guitar above. To get rid of that click sound - as I remember it - I just increased the attack time. But I'm not 100 % sure I remember right. I didn't succed very well in getting the Oxe-filter or -resonance to work very well, but as far as I know it isn't forbiden to use external stuff.
