Thanks, John! I erred. John is correct. At 250 quarter notes per second, the notes are spaced at 240 msec. �With 360 ticks per quarter note, a duration of 17 ticks is equivalent to 14.0 milliseconds.
I believe it is safe to say that intended notes of that short duration and low velocity that are recorded by a performer on a DKV( and that actually sounded when recorded) are unlikely. Nevertheless, a Mark II C Series will play them. �

Actually, it looks like each (white) note lasts 14.0 milliseconds, and they\u2019re 240.0 milliseconds apart.� And, all the NoteOff values are 0.

For those interested, I'm attaching a short midi file (type 0). �The duration of each note is 31 msec, approximately, and all notes are of velocity 10. �When this file is played on my Mark II DC3, all notes sound.
