There've been a lot of complaints over the years about midi timing and that it's not as accurate as, for instance, control voltage. Many musicians who've used Atari in the past with applications such as Notator swear that the timing is tighter on the older Atari than the modern day interfaces. Probably because the midi connections are an integral part of the hardware. Norman probably uses older 12 bit samplers as they give a much nicer effect than the modern bit crushers and a lot of the editing software is Atari based.
