After many years of digital, I am dragging out my old tape gear just because I want to have something new (old?) to mess around with. I have an Audio Technica RMX64 portastudio and an Otari 2 track reel to reel. I was given the Otari 8 or 10 years ago and haven't ever used it with the portastudio for bouncing before. I will be recording tracks on the portastudio and bouncing to/from the Otari. The RMX64 has Dolby B and C, the Otari has none and I don't have any outboard noise reduction gear. Can anyone offer advise as to whether I should use noise reduction and when I should have that on or off?
