Well; I took it to mean non-mechanical - or at least non-manual - control of the transport. The RT-707 Pioneer reel to reel sports 'logic control' from 1978, and they define that in the manual as meaning you can go from forward to play without pressing stop... the implication and actuality was that on pre-logic control kit it was easy to get the buttons jammed by pressing them too quickly one after the other, or to cause belts or gears to jump because the transition between the two mechanical states was too sharp. On most earlier reel machines for example you had to go to stop before play when forwarding and rewinding. Having 'logic' control the transition - with solenoids operating the mechanics based on electronic feedback from the electronic switches, rather than manual paddles and levers - meant it could be controlled more precisely than would be the case with a typical overenthusiastic hi-fi buff at the controls
