Just purchased one of these from zzsounds. Right now, I can only play through the usb from my computer and am unsure if my mixer is broken or it's a software issue. Trying to put on the filters onto channel 1 (the only channel with usb input) and both Filter 1 and Filter 2 don't affect channel 1 at all. Can't find anything that would hint the usb input can't be used with the filters, and I don't have a way of testing if the filters work at all at the moment. Anyone with insight?
