MessageThanks, Peter.  I do have an option labeled "20 dB boost" on the =
mic volume control, specific to my sound card.  It seems they use the =
same logic as for inharmonicity measurement; I was really surprised when =
hitting the spacebar didn't force the same action of sampling the note.

  Cy,
      I've never used the '97 version, but here's a possible solution:
  Try pausing before you strike the next ascending note.  The computer =
is looking for  a sudden jump in volume.  Your computer / mic may have =
an automatic gain control and when the volume of the sound begins to =
drop it "listens harder" or amplifies the decreasing amplitude (?).  =
This means even though you hear a sudden peak in the volume, the =
software doesn't.  Thus the computer tells you "waiting for trigger."  =
You can watch the spectrum display and see when the peak drops, then =
strike the note.  You may want to experiment some with the mic placement =
and volume (located under volume/recording control). =20

  Good luck,
  Peter Lamos
