yes, that snippet I gave you plays channel 0 program 0, I suspect there
is also some command for playing what is at the cursor in
channel/program that belongs to the staff the cursor is in.

So in addition to the play command my snippet has introduced, there is a
play according to the staff settings for what is at the cursor.

Not sure what that is about ...

I guess you refer to playing using the staff settings for
channel/program (ie MIDI instrument chosen for staff) here?

Well, the duration for the snippet is also prescribed in the
d-PlayMidiNote (as 1000 ms for a duration of 1 second)
if the note is played by the insertion command for the duration that the
written note prescribes then the MIDI note off message will cut off the
note being played by d-PlayMidiNote if it is in the same channel...
