Forgive me if I'm posting this in the wrong section. I'm new here. I would like to upgrade from my cassette based Tascam 488. I need more tracks and editing capabilities. I'm guessing digital is the way to go but should I go stand alone unit such as the Roland 1680 or since I don't own a computer yet, buy a computer and kill two birds with one stone? I can buy the 1680 and effects cards for around $2500. What will everything I need cost me going the computer route? Any difference in the sound quality between the two different ways? Which will have the steeper learning curve. Which way will be more easily updated? Any and all opinions welcomed! Thanks
