	Electronic musical instrument Summary
		But beyond the voice, other musical instruments have been developed over the millennia because of a desire to extend the range of sounds that are possible for the listener to hear.
		Simple electronic musical instruments are sometimes called sound effects; the border between sound effects and actual musical instruments is often hazy.
		The most commonly used electronic instruments are synthesizers, so-called because they artificially generate sound using techniques such as additive, subtractive, FM and physical modelling synthesis to create sounds.

	Musical Instrument Digital Interface - Wikipedia, the free encyclopedia
		Musical Instrument Digital Interface, or MIDI, is an industry-standard electronic communications protocol that defines each musical note in an electronic musical instrument such as a synthesizer, precisely and concisely, allowing electronic musical instruments and computers to exchange data, or "talk", with each other.
		Electronic musical instruments, including synthesizers, samplers, drum machines, and electronic drums, which are used to perform music in real time and are inherently able to transmit a MIDI data stream of the performance.
		Traditional instruments such as drums, pianos, and accordions which are outfitted with sensors and a computer which accepts input from the sensors and transmits real-time performance information as MIDI data.

	Sampler (musical instrument) - Wikipedia, the free encyclopedia
		A sampler is an electronic musical instrument that can record and store audio signal samples, generally recordings of existing sounds, and play them back at a range of pitches.
		An early form of sampler was an instrument called the 'Mellotron' (later Novatron due to licensing issues) which used individual pre-recorded tape loops, one under each key on the keyboard.
		Akai entered the electronic musical instrument world in 1984 with the first in a series of affordable samplers the S612, an 8bit digital sampler module.

	History of Electronic Instruments and Film
		Yet his concept of a multi-timbral and highly flexible electronic musical instrument (the first to employ additive synthesis) controlled by a traditional musical keyboard had established, if unsuccessfully for the moment, a vision that would not again be fully realized until the invention of the synthesizer half a century later.
		In 1917, he designed the prototype of the theremin (or thereminvox), an instrument that allowed the musician to modulate an electronic tone (fixed to resemble a violin) by moving her hands in proximity to two antennae (one for pitch, one for volume).
		In fact, despite its significant contribution to film and popular understanding of electronic music, the theremin was something of a commercial failure in comparison to one of the instruments it inspired.

		If you ask just about anyone who owns an electronic musical instrument that was made since 1984 or so, the answer you'll get is likely to be, "It's those plugs on the back." And that answer is right, as far as it goes.
		It was developed jointly by the major manufacturers of electronic musical instruments, and as such, represents a cooperative effort of impressive proportions.
		A typical MIDI instrument will have some kind of audio output, whether it consists of built-in speakers or jacks for connection to external amplification; this audio output is necessary for you to hear the sound that the instrument produces.

	Electronic musical instrument - Patent 4483229
		The present invention relates to an electronic musical instrument and, more particularly, to a digital tone generating system suitable for the large scale integrated circuit (hereinafter referred to as an LSI circuit).
		17 is a block diagram of an electronic musical instrument in the third embodiment of the present invention.
		The major portions of the electronic musical instrument, even if the microcomputer is contained, can be constructed on one printed circuit base plate, thus resulting in a remarkable progress as compared with the conventional construction using the ten-odd or several tens of printed circuit base plates.

		Most early instruments were designed to be played in ways analogous to traditional acoustic instruments, while a few enabled musicians to create music offline by mechanical programming.
		As the technical base of electronic musical instruments has shifted from vacuum tubes to transistors, to integrated circuits, to very-large-scale digital chips and complex software, the factors governing the instruments' 'playability' have also shifted.
		Considerations regarding the timbral and response characteristics of electronic musical instruments will be discussed, and directions for future development will be identified.

	Take an Electronic Odyssey with inventor Theremin (Site not responding. Last check: 2007-10-08)
		The eponymous electronic musical instrument of the late Lev Sergeivich Termen represented a turning point in the nascent phase of electronic technology.
		The futuristic Theremin was the first musical instrument to employ electricity and amplification (it has the capacity to out-blast an orchestra of 200 people).
		It is also the first musical instrument (other than the human voice) that is aurally transmutative, yet, paradoxically, was and is the only "non-contact" musical instrument.

	Casio v. U.S.
		(c) the term "electronic musical instruments" embraces all musical instruments in which the sound is generated electrically, and conventional- type instruments not suitable for playing without electrical amplification, but the term does not include conventional- type instruments, fitted with electrical pickup and amplifying devices, when the instrument is suitable for playing without such amplification.
		We deem it essential to its classification as a "musical instrument" -- in the absence of some indication of legislative intent to the contrary -- that there be a capability in an organ of producing sound when played upon.
		The court further emphasized its position that audible sound was required for proper classification of an article as an electronic musical instrument in a later section of the opinion discussing the adequacy of the assignment of error.

	Artifact: Full Record for 120 years of electronic music : electronic musical instrument 1870-1990
		Description: Created in 1998, this is version 3 of a web site, which documents the development of electronic musical instruments from 1870 to 1990 - although the main focus is on instruments being developed from the beginning of the twentieth century to 1960.
		Electronic musical instruments are defined here as "instruments that synthesise sounds from an electronic source".
		Hybrid electronic instruments from the end of the nineteenth century are left out of this definition and some non-electronic instruments (for example, the Futurists' 'Intonarumori') have been included, since it was thought that they were important in the historical development of modern music.

	Moog Patents
		Possibly the most famous electronic music patent ever, this is the guts of the circuitry for the Moog 904A voltage-controlled low-pass filter, the Moog 904B voltage-controlled high-pass filter and the Moog 904C filter coupler.
		Bob Moog probably noted that a filter for musical applications should have a steep slope (24 dB/oct in this case), should have the resonance adjustable without affecting the tuned frequency (and vice-versa), and that the resonance should be adjustable to oscillation.
		In the early days of hobbyist electronic music a VCA or VCF was often implemented on the cheap, avoiding transconductance amps and matched transistors, by pulse-width-modulating a CMOS gate at a high frequency to simulate a voltage controlled resistor.
