I actually kind of like this idea for not only the Prime 4 but the SC Prime players. He’s right that it does take quite a bit of extra time to load, play, stop, load again just to hear tracks. And every time you’re doing this it starts to analyze if they’re not already analyzed (mine aren’t).
The other related thing I’ve asked for is that touch or (holding the record significantly on the M) counts as the track being paused or stopped per the loading lockout, that way you can just put your hand on the platter to stop the music and load faster without bothering with so many button presses all the time. If your hand is on there, it’s not like it’s going to accidentally load a track, anyway. Loading becomes a pretty intentional and foolproof act without the need to outright turn load lockout off that we do need particularly because of the layers. Hand on the platter stopping the music should also allow you to set the main cue zero without having to press shift, too.
