Hi Mindenblues. Some of this I understand, but most of it is over my head. :? Do you mean that you use a regular notebook computer and plug in extra microphones to it? And does any notebook-type computer work? As per past discussions, I want to buy an Edirol someday, but I also need a notebook. I fear my clunky old desktop computer will give up in the near future. So if I buy a notebook, I can use it to record my piano playing? Then I don't need an Edirol, right?
