NM1600 - Test One Revision Notes

MIDI is a Musical Instrument Digital Interface - a widely used standard for interconnecting electronic musical instruments and computers.

MIDI was primarily developed to eliminate autonomous electronic instruments.

MIDI has been developed for a number of reasons firstly enabling the connecting of one instrument to another, connecting multiple instruments for different sounds through a 'split' setup.

MIDI was primarily developed originally for connecting one instrument to another. Today it is possible to connect a MIDI device to a USB interface to interact with MIDI software on a computer. Now it is possible to buy a USB/MIDI controller keyboard directly to a computer eliminating the need for a usb-to-midi interface.(Computer based midi setup)

Is MIDI Audio?

MIDI is not audio it is 'data' that represents musical elements such as notes. A Midi note is an instruction for an electronic instrument. The instruction does not enter the digital realm until it passes through a Digital to Analogue Converter (DAC)

What is the MIDI Data?

MIDI DATA is composed of three numbers. Say the numbers are

144      69       64 

Status Byte - 144 - Represents the note being plays on MIDI Channel 1.
Data Byte - 69 - Represents the note A above Middle C. The possible values of MIDI notes range from 0 to 127.
Data Byte - 64 - Represents the volume of the MIDI note / sound.The possible values range from 0 - 127.


With the REASON software used in this subject we work with a Subtractor Synthesizer
 that creates a complex sound (rich in harmonic content).

The Sound source can have oscillators which is a sound based upon a mathematical equation. The key ones are, square, sawtooth /| and triangle /\

Bits 'n' Bytes 

Midi Protocol uses Binary data to communicate it's messages. A above Middle C = Decimal 69. Which becomes the BYTE 01000101.

Techno - Techno is a style of music that has a fast style, heavy electronic dance music with few or no vocals

Steve's Definition: A technically Based form of dance music influenced by origins in (and rhythmic layers of) mechanical/industrial environments of 1980s Detroit.

Prior to MIDI a form of music was developed known as Electro an instrument used during this period was the Kraftwerk.

So what's Techno in the end??? The Dance Music Manual, Focal Press from Oxford puts it this way... Techno defines itself "on a collection of carefully programmed and manipulated textures rather than melodic elements" (Snoman 2005)

Techno consists of a minimum of 3 different loops, a tempo of 130 - 150 beats per minute (bpm), the time base signature is always 4/4 (with a solid kick pattern on each beat of the bar, A basic drum loop used as the core rhythm and additional loops and similar sounds (heard separately to the original sounds)

House - No note your House! - House Music

House music is a genre of electronic dance music that has fragmented into a wide range of subgenres. It draws inspiration from its origins in disco and from jazz, soul and techno. (Steve)

House consists of a 4/4 beat with a tempo ranging from 110bpm to 140bpm.

Bass lines are generally the driving force, pushing the beat and setting up a rhythmic pattern or grove with the drums.
