I have a problem...I went a little crazy and got way too many things daisy-chained via USB (midi controlers, interfaces, hard drives) in my studio, including four focusrite 18i20s hoping to be able to get all 32 channels out of them. but I know it was wishful thinking since my 13-inch MacBook running logic won't be able to handle all the data, at least without massacring the sample rate.
