How do you make it stop?

[XORadmin]

Shift+Stop will stop the whole sequencer (i.e. all active patterns). Is that what you are trying to accomplish?

No, I want to have the sequence stop on its own, and be ready to start again as if I did press Stop or Shift+Stop.

I've seen comments about setting bpm to 0, and that works, but then the clock is stopped 
and the sequence is hung in that pattern with the BPM command.

Is there a simple, more usual method that I haven't found out about yet?

They are multiple possibilities for it:

1- you choose a 'stop track' in the sequencer screen  ( it is ** you get when pressing SHIFT+DELETE on an empty spot) -> stops the track
2- SPFX FX command 002 Stop Track, 003 Stop Song
3- STSP FX Command and point to where a ** is on the sequencer screen to stop the track
