Midi track continues playing when I pause playback

Has anyone had a problem with the midi tracks continuing to play a tone after you pause playback? I don’t have this issue when I am recording the track, just when I am playing it back. The only way I can get it to stop is to mute that track and then unmute it. I am using Ubuntu Studio with Ardour 7.5 on an older laptop. Thanks!

See the MIDI Panic button…

Essentially the synth/sampler/etc. don’t see the command to stop playback, and instead just sustain the playing notes, the Midi Panic button will send a note off on all keys on all channels IIRC (But not really certain on the technicalities, so someone else may give a better answer).
