The harp on the right is a 36 string electric acoustic "Northern Lights" harp with RMC individual string transducers, and eight halogen spot lights with colored gels in the pillar, and fiber optic lighting that lights up crystal stars embedded in the sound board.
Here is one of the recordings Christina made with this harp: Christina Tourin Plays her Electric Light Harp on

Three or Four Transducer Array, Sound System ( For acoustic, or hollow-body electric harps only)
I can build all my many different harp sizes and styles to be electric acoustic harps, by using a multi transducer array, that is attached to the inside of the harp soundboard.
Using three or four carefully placed piezo pickup elements, this system achieves a clean, focused, natural, and lush sound. The rich, full bass notes balance and blend with the clear, musical MIDI and high notes. It’s simply the sound of the harp, only bigger. This system works at any volume level, without feedback, which can be a concern with microphones alone, when playing at extreme high volumes or with other instruments.
The four (or three in the smaller array ), transducer elements are discreetly mounted inside the sound box of the harp. All wiring is neatly bundled and run through a cable conduit that terminates at a single 1/4-inch jack that’s flush-mounted in the back of the harp, making for true “plug and play” ease of use. A single guitar cable allows you to plug your harp straight into any amplifier and many PA systems with no preamp boxes or complicated connections.
If you are playing in situations requiring very high volumes, you’ll want to add a preamplifier to the system. In addition to boosting your signal, it will give you direct control over your volume and tone. With some amplifiers it will also sweeten and smooth out your sound.I can install this transducer system for you in any of my Mountain Glen Harps

The Harp Mike
To add additional depth to your performance or recordings I am pleased to offer the Dusty Strings Harp Mike as a versatile, effective tool for amplifying your Mountain Glen Harp.
Many harpists like the idea of an actual microphone because of the warm, natural, open, and spacious sound that only mikes will give, until now there has not been one with a mounting system that worked well on the harp, or with electronics tailored to the harp’s unique sound. So this mike was developed with specialty microphone manufacturer Applied Microphone Technologies who designed one specifically for the harp.
The Harp Mike attach s to the back of the sound box by gently gripping the edges of one of the sound holes. This unique clamping design allows for mounting on nearly all the lever and pedal harps being made today. Unlike a microphone on a stand, the Harp Mike moves with your harp as you reposition it or tilt it back to play, keeping your sound consistent. It’s also discreet, out of your way and out of the audience’s view. It mounts quickly, with a few turns of a single knob, and uses no sticky tape or putty that can mar your harp’s finish. The microphone element extends out from the clamp on an extra-supple goose neck, making it easy to position in that "perfect" spot.
Since the Harp Mike is not permanently attached to your harp, you can easily switch it to other instruments. It can also come in handy for making voice announcements through your sound system. A 10-foot cord attaches to an included preamplifier, which can be powered by either a nine-volt battery or phantom power.The Harp Mike sells for $599

Mountain Glen MIDI Harps, can be built as solid body, or acoustic electric harps, with mixed mono audio out put, with any number of strings, from 25 up to 45.
MIDI is the digital language that electronic musical instruments communicate with. The important point to remember is that any brand or design of gear will work together, if it says MIDI on it.Here is how my midi-Electric harps work:
MIDI is a digital language that electronic musical instruments use to
communicate with each other and with other types of electronic gear.
(The acronym stands for Musical Instrument Digital Interface.) It is a
worldwide standard, so all MIDI gear is compatible.
An electronic message travels out through the cable to the synthesizer that you have connected the harp to. If you plucked middle C, the message will say "note 60- ON." When the vibration of the string stops, the harp will sense this and send out the message "note 60- OFF." As a bonus, additional information is sent at the same time telling the synthesizer how loud to play the note.
We are most familiar with keyboard synthesizers. By definition, the
keyboard itself is a MIDI controller. Usually, there is also a
synthesizer (sound producing module) built into these instruments. The
keyboard controls the internal synthesizer using MIDI commands. My MIDI
system enables a harpist to control any MIDI synthesizer using a harp
instead of a keyboard (including the one that is in your keyboard
The nature of the sound you actually hear is dependent on your synthesizer or sampling device, and your amplifier and speaker setup. If you plug the harp into the back of an inexpensive keyboard synthesizer, you will hear the usual keyboard synthesized sounds when you play the harp. If you plug the harp into a newer rack mounted synthesizer, some very convincing sounds will be produced.
Exciting possibilities result from plugging the harp into a computer that is running audio production software. It is possible to trigger high quality snippets of recorded sound in response to your string plucks. Of course, your computer must be connected to high quality sound equipment (amplifier and speakers) in order to realize the maximum effect.
By using DK harp pickups on each string of a harp, the activity
of each of those strings is kept separate. In this way, I do not have to
employ any complicated pitch recognition system. For example, when you
pluck the middle C string, the pickup that is in contact with that
string generates an electrical signal. That signal goes directly to the
microprocessor embedded in the harp, which responds by triggering the
MIDI message "note 60-on." In addition, the velocity (how quickly the
current rises) is measured, so the message sent to the synthesizer is
truly representative of the manner in which you pulled the string. All
information is updated every 8 milliseconds, so what you hear coming
from the synthesizer is truly representative of what the harp string is
doing. When the string vibration decays below a certain threshold, the
MIDI message "note 60-off" is sent to the synthesizer.
The microprocessor circuit board that I use has 48 inputs, so I can build any size harp up to 45 strings, with this system. The board senses electrical activity and intensity coming from each plucked string. No pitch recognition is involved, so there are no time delays.
There is a connection point for a sustain pedal, so these messages can also be sent from the harp. In addition to sustaining sounds, this tool is very useful in entering music directly into your computer, for publishing.
I am currently producing MIDI acoustic-electric harps with nylon or gut strings, that have all three options- acoustic, electric, and midi controller. I can also build solid body harps that are both midi controllers and analog electric harps, but have no acoustic sound, except the sound that the strings will produce with no acoustic sound board. This system can be installed into any of my single string band custom harps, from 25 to 45 strings.
I have also create one harp with acoustic-electric-midi, with Lasers Beams
as well, for a midi triggering highly visual performance style, using a
state of the art software that can trigger any sound or visual still or
video imagery, up to 60 times per second.
This system uses the DK individual string transducers, which produce a mixed mono audio signal, in addition to the MIDI signal. At this time, stereo audio output is not available with this MIDI system.
The controlling circuit board which contains the embedded microprocessor
also acts as a preamplifier and summing amplifier for the analog
electrical signals that the pickups are producing.
By mixing the sound of the electric harp with the sound being produced
by a synthesizer a whole pallet of sound colors are at your fingertips.
I can build this system into any of my custom single string band, nylon or gut strung harps. The individual string transducers are too wide to fit into normal wire string spacing, though with wider finger-tip wire spacing, they will work.
