NO--NO--the MIDIPort>>primitivePutMIDIOn primitive takes an arbitrary message
packet, which is typically a note-on or note-off message alone. The low-level
driver has no automatic-note-off scheduler, so Squeak-level processes are
*required* to do this. The MIDIPort class has interfaces for note-oriented or
packet-oriented output. Take a look at the on-line doc. at
