The last line shows the track chink is 35 bytes long. Did you play it
to the end? The third outlet of [midifile] emits a bang when it gets
to the end.
If you waited a while after starting to record there may be a long
pause before something happens.
The [dump 0( message should output the entire track to the Pd window.
