I don't remember, if this will work in GB '09, but in GB '11 you will get a longer sound, when you press down the "Sustain" key (the "tab" in Musical typing). Place a little weight (a coin or something) onto the sustain key, if you do not want to hold it down yourself.
or increase the Release value.
Yes, this will work, but is not rather iconvenient to have to go to the Track Info Edit pane of the sound effect instrument and the instrument settings, if you want to stop a note? If you increase the release value, this will apply to all notes alike.
