masterlink and mastering
I LOVE this unit, and feel that it can be used very well as a mastering unit, if you know what you're doing. For the record, I think it's easier to play a basic bass part then master this device.
I've had it nearly a year now, and through much trial and error, have learned to "play" this thing, like a musical instrument, to get a sound that sounds like a commercial CD release. Be warned, the owner's manual tells you as much about mastering as a guitar's owner's manual tells about playing the guirtar.
With patience, this thing IS unbelievable.
