This file is one of my compositions. There are some pedal commands, so some notes can be stuck after stop playing(F6 key).
So we can press 'Stop' key once again to shut off these notes.

9th staff(Staff-8) includes pedals. If this staff gets played, and stopped, the pedal sound still remains.
I think this is on a sound card by sound card basis. For example, it doesn't happen with my sound card.
Hitting F6 when music is playing is a stop command. Hitting F6 a second time is a reset command.
What it does is to reset some controllers and sends a note-off midi command to every channel.
It also clears pitch bends and volume and such things.
In other words - if you have changed these sort of items in your music, it resets so thatyou can start again from new as if nothing had been played.
I'm not sure if there was a question in your post - or if it was for information or if you were asking if you were correct. But I hope the above helps.
