[PD] Recording MIDI results in notes of infinite duration

[Luke Iannini (pd)]

Hi David,

Thanks for the reply.  I used the Helpfile abstraction as an example
as I figured it would mean I couldn't have screwed anything up
Pd-wise.  I'm aware of the note-on/noteoff necessity; both messages
(with velocity and with 0, and the 0 velocity notes come after the
non-zero-valued-velocity notes as one would expect) print quite
happily in the Pd console when using both my patch and the the
helpfile's simple version.  But even without the noteoffs, does this
explain the notes all beginning at the same point?  I find that
particularly strange.

Thanks!
