Engraving for harp as a member of an ensemble, to play midi, use piano as midi instrument?

[Kenneth Wolcott]

Hi;

  SInce a harp is not a recognized midi instrument, when using midi to
verify that the rhythm and pitches are correct, should one designate
the midi instrument as an "acoustic grand" or will it automatically
resolve to that instrument?

  I'm looking to engrave (possibly) the full orchestral version of
Swan Lake (ambitious, eh?), and, of course, the harp is an essential
instrument.  I'd like it to sound as authentic as possible under midi
(obviously not going to have a full string section, etc).

Thanks,
Ken Wolcott
