General MIDI 2 is a group of extensions made to General MIDI 1 in 1999, which increases both the number of available sounds and the amount of control available for sound editing and musical performance.
MIDI is almost directly responsible for bringing an end to the "wall of synthesizers" phenomenon in 1970s-80s rock music concerts, when musical keyboard performers were sometimes hidden behind banks of various instruments.
General MIDI (GM) was an attempt by the MIDI Manufacturer's Association (MMA) to resolve this problem by standardizing an instrument program number map, so that for example Program Change 1 always results in a piano sound on all GM-compliant players.

General MIDI is a specification for synthesizer ((music) an electronic instrument (usually played with a keyboard) that generates and modifies sounds electronically and can imitate a variety of other musical instruments) s which imposes several requirements beyond the more abstract MIDI (The south of France) standard.
While MIDI itself does provide a protocol ((computer science) rules determining the format and transmission of data) which ensures that different instruments can interoperate at a fundamental level (e.g.
General MIDI was first standardised in 1991, by the MIDI Manufacturers Association (MMA) and the Japan MIDI Standards Committee (JMSC), and has since been adopted as an addendum to the main MIDI standard.

 General MIDI (GM)
In September of 1991 the MIDI Manufacturers Association (MMA) and the Japan MIDI Standards Committee (JMSC) created the beginning of a new era in MIDI technology, by adopting the "General MIDI System Level 1" specification (later renamed General MIDI Level 1), also known as "GM" (or now "GM1").
General MIDI 1 was designed to provide a minimum level of performance compatibility among MIDI instruments, and has helped pave the way for MIDI in the growing consumer and multimedia markets.
The General MIDI Lite device specification, released in 2001, is intended for equipment that does not have the capability to support the full feature set defined in General MIDI 1, on the assumption that the reduced performance may be acceptable (and even required) in some mobile applications.

A problem which has arisen as a result of the serial nature of the MIDI standard occurs when a user desires to edit a MIDI file by removing sections from one area of the file for utilisation in a second or subsequent file or by deleting and/or altering sections of an existing file.
Due to the serial nature of a MIDI file, the removal of a section of that file in a traditional "cut and paste" type operation may cause serious problems due to the removal of information which is necessary for the source file to continue to function.

MIDI - the Musical Instrument Digital Interface - is a protocol specifying how electronic musical instruments may be controlled remotely.
By August 1983 when the MIDI 1.0 Standard was formally published, two industry organizations: the MIDI Manufacturer's Association (MMA), and the Japan MIDI Standards Committee were now governing the development of MIDI.
However, shortly after the 1.0 standard was published, an additional document was published to solidify some vague areas like specifying which instruments should be on a given channel.

In a preferred embodiment of the present invention a filter control circuit is also utilized to limit the output of the filter to a maximum level so that output stability is always maintained, independent of the initial conditions and filter coefficients of the filter.
The MIDI standard permits the transmittal of a serial listing of program status messages and channel messages, such as "note on" and "note off" and as consequence require substantially less digital data to encode than the straightforward digitization of an analog music signal.
However, the relationship between MIDI note numbers and W.sub.c may be expressed as shown below: ##EQU4## Since we are interested in relative performance, the cosine argument of equation (6) may be represented by the following: ##EQU5## Where C is a constant.

 History of Midi
MIDI commands consist of one or more bytes of data, and include such things as note on and off commands, clock synchronization, etc. These commands are transmitted serially, at a specified rate of 31250 bits/sec, but most MIDI messages have a slot for a channel number.
Even with these additions to the MMA's standard, the MIDI format is not sufficient, by itself, to produce a full musical score, nor as a storage mechanism for such a score which has been parsed electronically.
MIDI is not without its limitations, made all the more problematic in that they are not just accidents of implementation - they are inherent in the underlying models that MIDI builds upon.

 MIDI BASICS
Messages received at the MIDI In jack are split: one copy of the message stream enters the slave, which responds in the normal manner, while the other copy is diverted to the MIDI Thru jack, which sends it on to the next connected slave.
MIDI includes code numbers for 128 chromatic notes (numbered from 0 to 127), which exceeds the range of a piano and was deemed sufficient for most musical situations.
Although MIDI is designed to be a common language that all electronic musical instruments can understand regardless of their manufacturer, the designers of MIDI decided it was important to be able to encode information that is unique to each instrument, such as exactly how the instrument generates its sound.

 WHC Report of the Bureau, 24-29 June 1996
IV.2 As to the Eleventh General Assembly, it was noted that the Committee at its nineteenth session prepared already a draft resolution and that it requested the Bureau to prepare a report for examination by the World Heritage Committee at its twentieth session and for subsequent submission to the General Assembly.
As to the draft resolution prepared by the Committee, the Bureau was of the opinion that it was the result of long and substantive consultations among the Committee members and a great number of observer delegations, and that, therefore, no substantial changes in its text should be considered.
The Committee, therefore, decided to retain the site on the List of World Heritage in Danger and requested the Bulgarian authorities to prepare a status report on their efforts to restore the site, to be presented in three year's time.
