9.1 EXPLANATION OF TERMS
Term Definition
MIDI
Musical Instrument Digital Interface is a data transfer protocol. With this,
musical control information is transferred between electronic instruments
such as digital pianos, keyboards, synthesizers, drum computers or even
PCs or laptops. To exchange this control information, the instruments/
computers require MIDI connections and a link must be established
between them. There are different MIDI connections with various functions:
MIDI-IN (input), MIDI-OUT(output) and MIDI-THRU. The last one routes
received data untouched from MIDI to be used for other MIDI device.
Here‘s an example:
If a key on the digital piano is pressed, digital data packets are sent from
MIDI In to MIDI out (MIDI-OUT). The data packets contain information
on pitch, keyboard dynamic and the duration of the keystroke. The
data packets output can be e.g. recorded, stored, played back on the
computer and also displayed as notation on the screen if the application
is able to do this.
Recorded MIDI data can then be sent to a MIDI instrument, e.g. a digital
piano, to make it audible again.
GM
General MIDI defines a lot more than what is defined in the basic
MIDI protocol. It combines hardware and protocol specifications.
General MIDI also specifies content. For this, GM sets a minimum
standard for the assignment of the instruments to 128 program places.
According to GM, a compatible GM MIDI instrument must be able to
generate 24 sounds simultaneously. Furthermore, according to GM,
additional control parameters are defined, such as e.g. effect control.
General MIDI
standard sounds
Sounds or instruments in compliance with the specifications of the General
MIDI standard protocol
Reverb This simulates a room environment. It is preconfigured for some sounds to
give them a more lively and realistic appeal.
Chorus
The chorus effect adds another slightly detuned note to every note that is
played. This produces a fuller ensemble like impression.
Samples
Samples are audio clip recordings from natural instruments. All sounds
of sampled instruments are recorded and saved to logically defined
locations. This then leads to an organized sum of sampled single notes,
which, when played back, sound like the originally sampled natural
instrument.
Polyphony
Maximum number of simultaneously playable notes. A high number of
simultaneously playable notes ensure a highly natural sound impression.
