Casio DH-100

This 'horn' is in good working condition.

This is more than a toy, but comes up short of being a fully-fledged musical instrument.
You can play it independently, walking around outside, since it has battery power and an internal speaker.
Or, you can hook it up with an AC transformer for power and run a midi cable out to play a variety of sounds.

Sold - Dec. '06

You can probably find these a little cheaper on eBay, if you want to go that route.

I ran a MIDI cable from this horn to a MIDI port on a Yamaha keyboard and was able to make the keyboard play using the Casio DH100. I know very little about MIDI, so I didn't get much further than that.
I think that with the proper synth one could play virtually any sound sample you chose.

It can be played either in 'Breath' mode wherein you blow into the mouthpiece and the harder you blow, the louder the note. You can control attack, etc. Or you can play in "Non-breath" mode where pressing the keys makes the notes, without blowing into the sax.

It can be played in either 'Recorder' fingering mode which gives you two octaves range. Or it can be played in a special Casio fingering mode which gives you five (I think, I'd have to look at the manual) octaves range.

That reminds me, I downloaded the manual in PDF format and printed out a copy which you are welcome to have.

Here's a Cybersax article on EWI's.
Repairing the squeal problem is pretty easy. I did it. I also bought some spare capacitors so I can do it again..

At the bottom of this WebPage there is some interesting information on hooking the DH100 up to a sound module. And of course Patchman Music is maybe the best source.

From Matt at Patchman Music I learned:
You hook the DH100 to a "Sound Module" using a MIDI cable. The Sound Module is a piece of hardware that may or may not have a keyboard on it. With the correct sound module, you can somehow download software (or is it firmware?) called a Sound Bank into the Sound Module. There are special Sound Banks optimized for EWI's. Patchman refers to the SoundBanks by the name of the Sound Module into which it loads. I found that confusing.
Certain Sound Modules work better with DH100's
The Patchman website says:
Casio DH-100 / DH-200 OWNERS TAKE NOTE: Since our Korg 05R/W, M1, M3R, T1, T2, T3, and X5DR sounds are set up to respond fully to aftertouch data, they work GREAT with the Casio DH Series horns such as the DH-100 and DH-200. If you wish to use the Casio Horn with our other banks that are set up to respond to breath controller data (MIDI Continuous Controller #2), you will need a mapper to map the Casio's Aftertouch data into Breath Controller data.

Another website says:
The Casio Horn does not actually produce breath control - but the MIDI signal for afterpressure - the trick then is to convince the afterpressure to become a breath control signal. This is achieved by use of MIDI-ox.The software on the PC can be configured to turn one MIDI message into another,once this is done,the remaining problem is that the NOTE ON and OFF from the Horn still produces a note on the DX - luckily MIDIox can get rid of the NOTE ON and OFF information too.The result when the output of the PC is fed to the DX is a MIDI signal producing breath control which alters the timbre of the DX.

The mouthpiece is a little chewed on looking, but I washed it and it works fine.

Sanborn on DH100.
