frank, i was about to buy the uc-33 !!! i didnt have too much money so i went for the xsession, but i guess those extra sliders are very useful!!! to treat it more like a real mixer... anyway thank you very much for the info, im on my way to install the usbaudio, im on vacation so im setting up everything (all the computers and midi stuff) the thing that i wanted to do is to connect the creative sb extigy (usb soundcard) too, but maybe ill mess with having multiple midi interfaces (recent topic) ... thanx! ivan. _________________________________________________________ Do You Yahoo!?
