As the title says, if dmidiplayer is closed using the close window button on the window while a MIDI file is playing the last note will be left hanging/playing indefinitely or until playback is restarted and stopped manually. If the player is closed through File->Quit then the playback is stopped automatically before the application closes.
Reproducible with version 1.7.3 on ArchLinux running KDE Plasma.
