Well it is not really a problem but...I would like to solve it anyway!:-) Everything seems to run fine, but I can't set input channels level at 0.0 but only stepping from -0.1 to +0.1: I do not manage to hear the difference between -0.1 to 0.0 but I would really like to have a perfectly tuned system! :-P Can anyone help? I tried moving slides by mouse and no way to get 0.0 setting. Bye! Michele
