Introduction What is MIDI
MIDI is know as Musical Instrument Digital Interface. MIDI is one of the few ways thattechnology and music has developed together. Through the use of USB cables and dedicated MIDI
cables the MIDI is capable of bringing the ability to compose music perform music live and edit
music much much more easier than the traditional analogue methods.
Origins of MIDI
MIDI came about in the year of !"#$ where MIDI started with the
idea that a musician could control several synthesi%ers and drum
pads with one controller. This was first introduced via a &'(pin DI)*
cable which allowed MIDI keyboards to connect to each other and
transmit data. This was essentially adding oscillators onto each otheror running synthesi%ers through each other which is now commonly
done on Digital +udio ,orkstations -D+,s/. Through physical
MIDI instrumentals it is completely possible to use the older method
via a D+,. MIDI cables are now also in USB form allowing MIDI
Instruments to connect to computers.
Why use MIDI
MIDI allows people who are not able to play the instruments that they re0uire for their
composition to place MIDI data in a D+, that behaved in a similar style to a piano roll. )owadays
the form of this is called the &1iano 2oll* where MIDI data can be changed in almost any aspect
such as velocity panning pitch M3D 456 release etc... This allows a huge variety of ways to
develop the composition and feel of
the composition. If a producer knows
what they are doing with MIDI they
are fully capable to create music thatsound more &human* than &machine*.
This is needed when creating
orchestral pieces of music or when
using samples instead of synths so
they dont sound rigid and blocky
within the composition. MIDI with
its huge versatility and capabilities of
manipulating almost any variable
makes it essential for composers and
producers alike.

MIDI Types of MIDI Instrument
There are a huge amount of MIDI Instruments that are being producedby various manufacturers. Since MIDI is so simple yet effective it has
been integrated in various devices. Some are instruments such as
7eyboards ,ind Instruments Drums and 8uitars. Due to sheer
capabilities of MIDI it has even been integrated and become a key
integral part of stage lighting where MIDI controllers are able to
manipulate multiple lights on stage through mechanised motors and
saved programs9settings. Since not all MIDI instruments are going to be the same by each
manufacturer there are variations that tend to be present for each individual manufacturer. Such as
placement9layout of buttons on a MIDI keyboard casings for the instruments si%e and 0uality.
There are differences in si%e and preference with MIDI
keyboards as they can come in si%es ranging from $(: octavesand even a choice of whether the keys are weighted keys or
not to recreate the feel of an actual piano. Though this mainly
down to choice. The variety of MIDI instruments allows even
those who play instruments use MIDI in a way that is more
familiar to them that ;ust a standard MIDI keyboard.
How does MIDI work?
Using the Diagram below the MIDI data is sent in the form of Binary information -So in
modifiers on the MIDI instrument that have uni0ue identities and values on the machine the data is
being sent to -such as a low pass filter controller on an ambiguous dial on the MIDI Instrument/.
Since MIDI is raw data is does not have any sound to it therefore there needs to be a medium that
can translate the binary into sound. There are physical synthesi%ers that can process the data and
then there are D+,s. D+,s can
contain samples of instruments that
assign certain values to certain samples
and software synthesi%ers that areessentially the physical synthesi%ers in a
software format that do the same ;ob.
Through MIDI Interface ?ontrollers
Multiple MIDI signals from many
different MIDI instruments can be sent
to one machine and also be controlled
by that one machine. Since MIDI data
can also be edited post recording of the
data it means that if mistakes are made
or there are issues with the sound they
can remedied very easily.

Digita% &udio Workstations
What is a D&W?
+ Digital +udio ,orkstation is a piece of
software that runs on a computer and acts
as a controller device piano roll and in
general organises and allows fleJibility with the creation of music. +
D+, is capable of receiving MIDI signals interpretation them and
editing them using software synthesi%ers and audio samples to create
and produce music. Through the development of MIDI D+,s have
developed alongside them allowing all kinds of D+,s to be created each with their own style and
platforms they work on. D+,s such as Eogic and ruity Eoops can only work on their respective
platforms due to software limitations but programs such as +bleton Eive and Maschine work on
both platforms due to the way that they are programmed and designed.,ith the wide variety of D+,s available the 0uestion is what one
should you use. +nswer@ +ny. +s long as the D+, that you use
works for you then its absolutely fine though one must keep in mind
that the D+, they use will be limited in one way or another. or
eJample Eogic and E Studio are both locked to their respective
platforms of Mac 3S and ,indows 3S. Both will do the same
functions but they do not have the same type of support. or eJample
E Studio has native support for C$bit GST9GSTi plugins in Fbit
mode with a first party(support plugin to host +U plugins that are
native to M+? 3S in C$bit9Fbit mode. Aowever Eogic has to rely
on a third party plugin to be able to run GSTs while having native
support for +udio Units. 3n the flip(side Eogic has a huge
community basing allowing any issues that arise to answered 0uickly
and promptly by the community this can include even sharing music production methods and ideas
across the community. This is very similar to the ,indows ?ommunity vs Macintosh ?ommunity
Macintoshs lack the community aspect but are virtually issue free while windows has 0uite the
handful of problems but has a huge community that work together to fiJ the problem.
If you wish to use MIDI you will need a D+, also since MIDI nowadays relies on D+,s to do
the processing of data. Aowever there are some MIDI instruments out there that do not have to rely
on D+,S for processing and sound output.
