Howdy Don,

The name of it is Harmonica.sf2. It came as a zip file (a bit unusual), and is just under 2 Mb in size.

I also didn't find it at HammerSound - that's a bummer. If you want that one, I can email it to you (it says it's free for distribution and editing). There is also another one available at http://www.sf2midi.com/index.php?page=sdet&id=8262, but it's much larger (~8 Mb). It has the same filename, but it's definitely a different soundfont - more on the attack, but "breathier". Very good, just different than the other one.

I also have one called "Monsoon's Hohner C harmonica" that I picked up at http://www.sf2midi.com/index.php?page=sdet&id=6178 It's around 3 Mb, and is also good, just different than the other two.

If you'd like the first one that seems to be no longer available, let me know and I'll email it to you. The other two are available at sf2midi.com, but their server seems to be really slow right now, so it might take a few minutes to download the fonts.

And be sure to post your harmonica song when you're done, in the "Share your music" section - we want to hear

ttfn,
Sherry
