I suggested this user option as a means of dealing with a number of current issues like the cogging wobble at the end on the Ms, that wobble preventing the recently implemented mitigation against accidentally setting the main cue zero to the very end if you hit Cue after it stops from working properly, and the weird hot cue behaviors, not to mention it’d better resemble vinyl, but this was shot down by InMusic as being too inconsistent with the non-Ms if it was allowed, since it would not give a visual indication in the Play/Pause & Cue LEDs that the track had stopped. It seems to me that if the remaining time reads zero and there’s no audio on that layer, that should be enough indication of the music’s end on an M.
I suppose possible current solutions for you might be setting a loop, turning slicer mode on, or going into an audio editor and appending a bunch of silence to your samples.
